FA: “Sir, do you have a ticket?” Passenger: “Oh! Sorry, I must have dropped it somewhere around here…” FA: opens bomb bay doors. FA to the other passengers: “No ticket” *POV: you don’t have a ticket*
One huge factor: even if you ignore the huge load-bearing ribs when placing seats, the rear of the B-52 is not pressurized, nor designed to be…so you’d arrive with lot of suffocated and frozen cargo 😅
The first thing that came to my mind was those 8 engines - I mean the main reason airlines recently retired 747s was due to modern 2 engined airliners now being able to do what once needed 4 engines. I imagine most airline execs would laugh at anyone who pitched the idea of an 8 engined airliner.
the eight engines were actually a design choice at the time, and the aerodynamics of the wings & tail are designed around eight different thrust vectors: as the aircraft is re-engined, it gets new engines that produce an equivalent amount of thrust for smaller size/better fuel economy, but there has to be eight of them to fit the aerodynamics.
@@theodorbutters141 Actually, that wouldn't be possible. Newer engines have a much larger fan section and bypass ratio giving the engine cowling a much larger physical size. That would clearly cause a problem, especially for the outboard engines
@@sterlingstroebel Four engines would also require a larger vertical stabilizer and rudder. Possibly the entire empennage needs redesigning as well as the wing.
The advantage the Tu-114 had was mainly due to the fact the Tu-95's fuselage was removed from the equation and a totally new, larger fuselage was put in its place. The same was done by Convair with their experimental XC-99 cargo and troop transport, built out of the B-36B, Consolidated turning the B-24 Liberator into the Model 39/R2Y LIberator Liner and by Boeing itself funny enough, with the B-17 Flying Fortress into 307 Stratoliner and the B-29/B-50 Superfortress into the C-97/377 transports, tankers and airliners. Likely, the same would need to be done with the B-52. Same control surfaces and landing gear, but the fuselage is a totally new design that has very little in common with the original airframe. In terms of jet bombers, the Avro Vulcan and Convair B-58 both had planned airliner/transport versions, which never got off the drawing board.
I was going to add a note about the B-29/Boeing 377 Stratocruiser conversion but I see you covered it, demonstrating the bomber to airliner makeover has been done before.
Speaking of the XC-99, they actually planned an airliner variant of their YB-60 prototype, borrowing the wings, tail & engines from it, using the XC99 fuselage (2 decks) & B36 cockpit window configuration, planned and cancelled in the 1950’s, this would have been the 1st jumbo jet 2 decades earlier than the Boeing 747!
As I was a crew chief on the B52 H. One flaw is your upper seating deck is all fuel tanks and if you take them out then your range is cut drastically. Sure during Vietnam on the D models they did do the big belly mod of taking out the mid body tanks to put more bombs in the bays. Also I doubt you get 4 seats and a center isle in that fuselage. The landing gears takes up a huge area and goes pretty much to the bottom of the fuel tanks. In the end you would never get a B52 to use in the civilian aviation as the H model are nuclear capable. No way they will give anyone access to that. It to mention current engines on the bomber can use 3 to 4 quarts of oil in a 8 hour flight. Also the ride isn’t that great. Tastier to take the tankers which are basically commercial airframes and convert those. Even cargo planes would be better suited.
You're responding with facts and logic to something that is complete nonsense and should embarrass the hell out of the perpetrator and the fools he think his idea is not only possible, but good.
Having flown on B-52s during my years in the USAF, I was curious to see how you were going to modify the interior of this plane to address passenger comfort. I know how confining it was with just six or seven airmen aboard, so the idea of hundreds of passengers was unthinkable to me. We had a “relief can” that served as our comfort station. It was located just behind the navigators' position in the lower deck, and it was NOT private-this was the military after all. The truly massive structure of the bomber was its wings, which in large part helped carry the quarter-million-plus pounds of fuel that give the plane its extended range. Military gear in general is not designed for human comfort, but for utility, so form must follow function. Ergo they are designed from the ground up. Ditto with airliners. Interesting video nonetheless.
As another B-52 guy, pilot, I was curious where the fuel, to get the amazing range, was going to go when the fuselage was filled with passengers. We carried a LOT of fuel in fuselage tanks, we wouldn't het anywhere near the quoted max range without the fuselage tanks. And then you have the issue that, with max fuel on board, the payload was only about 10,000 lbs. To get that 60,000 lb bomb load, you. would need to reduce fuel load by 50,000 lbs, but you wouldn't have room for that fuel anyway.
Where is the wing box area ? The wing box attaches each wing and the fuselage all together, every other plane that I have seen has a wing box. On a low wing aircraft, people are sitting on top of the wing box. On a high wing aircraft like the C5, C141, C17, C130 they a along the top of the fuselage. The B52 wing box is where the passenger would be sitting, the airplane has to have a wing box where else can you attach each wing to each other and to the fuselage ? The picture in the video seems to missing this critical part of the aircraft structure all plane have a wing box.
As some who serviced civilian comercial airliners, beyond just luggage space & safety, the video neglected the need for water/lavatory services which would've likely reduce pax capacity even more.
A similar question I always had was what if the A350 was turned into a bomber. Considering neither France nor Germany have a dedicated bomber aircraft currently.
Who needs it when a fighter can deliver the same payload? edit 1: i was supposed to say that a fighter like the f-35 could carry a nuclear payload (b63) but never the full conventional payload of a strategic bomber
Fun to think about! Keep in mind the high wings require a wing box structure to connect to the fuselage and each other, so no passengers in that area either.
I've never been inside a B-52. But I've flown airliners with a similar wing configuration, F-50 being among them. There's a reduction in cabin ceiling height under the spars, but that's all. Due to this, the airline I was with had a maximum height of F-50 crew at 179 centimetres.
@@LordSandwichII Worth noting these are planes designed from the get-go to hold passengers, with design considerations and sacrifices made to not interrupt the passenger cabin. The BUFF was designed with none of this in mind, and modifying the wing box is probably simply infeasible, it's a structurally integral part, it's not like some solution can just be slapped on the thing. Yeah, other high-wing planes have wing boxes that don't interrupt the cabin, because this was a primary design consideration, and it's easier to build a plane up around those than come through 70 years later with a hacksaw, a dream, and a shitton of FEA.
Many problems with this presentation. Not only will the wing box affect the passenger count, but also system (electrical, a/c, waste and water), there's also need for baggage, lav and galley and door egress. Also complete structural redesign for a pressurized cabin. Some commenters mention the F-50 and BAE-146, both are single deckers, this is proposed as a double decker. And because of the payload capacity the wing box is probably much larger than those smaller aircraft.
Even when I was little and first getting into planes, I’ve always wondered why the B-52 was never made into an airliner. I love these sorts of presentations.
Military planes have wildly different needs. The Tupolev tu-95 was turned into one for the Soviet premier and it was godawful. The BUFF is not efficient at all. It doesn't need to be. It wasn't made to meet profitability standards, just carry an absolutely colossal payload in a very small fuselage. It also doesn't have the same maintenance intervals There were also plans to make a mach 3 business jet from a mig21 and it just would have never worked.
There have been a few large Military planes that were looked at for passenger service. Due to all of the specialization after the "piston era", it just doesn't work out. For example, they don't need the heavy duty (and thus heavier) landing gear.
@@rex8255 Yes, it worked after WW 2 as you could get the plane for scrap value and you could manage without a pressurized cabin for one thing. The cabin on the B-52 is large as its the only part who is pressurized I assume? Know the B-29 and 36 had an center crew quarter but that was for guners. Also the engines on a B-52 is very old and inefficient, does not matter as they don't fly much compared to commercial planes
@@magnemoe1engines have been replaced with newer, more efficient engines several times over the years. It’s currently being retrofit with high bypass engines used on several more modern airplanes. Most notably the B717, the upcoming Dassault Falcon 10x and the Gulfstream G500/600/700 series.
@@colinmartin9797 yeah, thats why military to commercial is dumb. But the opposite makes sense. They could make the 747 into a bomber. Or, use commercial cargo planes instead of the c-130, 17. They are meant to land on austere runways but mostly do not.
The AA livery looks great on the B-52! This just goes to show how quickly airplane design advanced in the mid 20th century, and of course, how planes are purpose-built.
The Dash 80, which eventually grew into what was the 707, was originally conceived as a Aerial Fuel Tanker for the B-47 and B-52. Some competition from Douglas, and the proposed Passenger version of the Dash-80, was widened, and became the 707
I have collection of many 1:200 model planes and including the B52, it looks even smaller than a 757 and most of it's size is actually come from it's wing rather than fuselage, so no chance.
In present day clearly not. Interesting to ponder if they'd built such instead of the 367-80 and 707 though, surely (like all other airliners based on bombers) they would have made the fuselage much larger to carry more people, at the expense of range. Bombs are very dense and need to be carried very long distances, while passengers weigh less, need more space, but don't need to go as far without refueling stops.
They are really small compared to what we see in videos. Stationed on minot afb and seeing them up close, the wingspan makes up the majority of the plane. Doubt there could be anymore than 50 people in it if it were a commercial liner.
A few other issues with converting a BUFF into a pax plane: the loss of a significant amount of range because you'd have to remove the three fuselage tanks to accomadate passengers. And there's that pesky center wing box (that also serves as a fuel tank). I imagine you'd make up some of that range lost with the BR700 engines that's replacing the current TF33's though
How much of that fuel storage could be made up if you had large fuel tanks on the external pylons? Either that or mount pods for luggage/cargo? Would the drag penalty be worth it?
@@johngalt2506 it's been a really long time since I worked on a B-52 so I don't remember how much fuel those tanks hold but I know it's a pretty significant percentage of the jet's total capacity. I am leaning towards the idea of external tanks being unfeasible though. I think the drag penalty would just be too high.
@@clangston3 The C and D models carried 300 gallon external tanks on every flight. Certainly they weren't unfeasible. They were very streamlined as you should recall and with modern engines efficiency they might be done away with but maybe not for the longer range versions. edit: correction 3,000 gallons each. See my other post replies for documentation.
@@johngalt2506 considering that it has a range of nearly 9000 miles im guessing if you cut that down to 1/3rd without a heavy load (passengers are relatively light) losing 2 out of 3 tanks wouldnt be that big of an issue. and plus... its narrow so everyone gets a window row!
@@chrisbaker2903 the external tanks carry around 375 pounds of fuel max in each. unfortunately they largely contribute to the jets weight and balance so you can't just get rid of them. the fuselage tanks carry a large portion of fuel as well, albeit the majority is in the 4 wing tanks. you could potentially compensate for the weight and balance the fuselage tanks provide with the passengers instead, but with that you shorten the range greatly.
When you calculate the weight of a typical passenger, you forgot to include the weight of the seat and cabin floor beneath that he/she will sit on :) Also, the bunk cargo shelves and windows alongside the fuselage will weight the whole aircraft down quite some.
The figure was just about right for the "per passanger weight including carryons", which is 85kg for males and 66 kg for females (on average). Of course, you have to add 16kg for an economy seat, the extra weight from pressurizing the cabin etc etc.
Generally, bombers are optimized to carry weight; airliners are optimized for volume. This will be a limiting factor whenever you try to do a conversion like this one way or the other. When you factor in things like legroom, headroom, luggage space, and being able to exit in an emergency people are orders of magnitude less dense than bombs. You can see this when you look inside tanker aircraft originally designed to carry passengers, they have mostly empty space.
I have a buddy who was a member of a B-52 crew -- he told me the very first thing the plane has to do when reaching 30-32k altitude is hook up with a tanker because at that point they are flying on fumes. Sounds a bit dangerous to have a plane packed with people.
@@michaeloconnor6683 B-52 has a combat range of almost 9000 miles unrefueled. Maybe they burn a lot of gas on takeoff and it makes sense to refuel after the climb since they are close to base with a tanker to increase that even further, but they are not "running on fumes".
@@chrischeezy7316 Absolutely - a total obscenity of a set of institutions bent on destroying European nations - although 1d10ts think it is something to do with European culture.
The B-52 has an incredibly small fuselage. When my family visited the Boeing plant in 1994, there was one sitting on delivery parking area adjacent to 767 and 747 it looked tiny like a 737 with big wings
Folks complain about traveling in Greyhound busses. They'd really ask for their money back, if they had to ride in a B52. Its a working plane, not a riding plane.
Oddly enough even though it's smaller than a 747, when you see one coming for a low slow pass over the runway during an airshow at Edwards AFB they come in straight from a LONG way out. You can see them easily at 20 miles and then it just keeps getting bigger and bigger and bigger till it seems like a real leviathan sized plane is going past. I haven't seen a 747 do the same thing, not sure they can fly slow enough, need to compare stall speeds when lightly loaded. The biggest airplane I ever saw was an F-4 Phantom II, at Point Mugu during their "Space Fair", that got a bit off course and flew straight over my head in the grandstands, with the flaps down and the hood down and I would swear that it was only about 200 feet up. That viewpoint made it the biggest plane ever built! LOL I'd love to have heard the debriefing he had to undergo after the show.
It is not an anorexic 777 it is just into lean fliying... First class (officers?) Would be the one with working radar and elint screens, and of course the movie should be something like dr. Strangelove, war games, damnation alley or hunt for the red october...
The landing gear are attached to very sturdy bulkheads that extend to the top of the fuselage. So, remove the landing gear and put them in "pods" like the C5.
I was waiting for you talk about how thirsty those 8 engines are and the cost per passenger kilometer to fuel and maintain those guzzlers as compared to say a 787 or A350.
Not to mention the cost to maintain eight engines. This is the reason why many major airlines are moving away from four-engined jets including the relatively newer A380 to two-engined ones.
Saw this concept described in an aviation "series" book on the B-52 many years ago. The book had to be from the mid-late 60's since i saw/read it around 1971. The proposed model was Boeing 464, I think. It addressed the gear problem regarding seating you described. The BUFF was a great plane, I flew the G and H models both during the waning days of SAC, some planes were actually older than I was. Quite a plane, still amazed they'll be flying til' 2050...
I had a LIFE book from the 60s as a kid my parents bought used from the library (I’m in my 20s) and the 747 was used as a concept for a military transport aircraft with no mention of it as a passenger jet where it found it’s eventual success.
I worked on G models 87-91. I think the noise would be an issue. They made the ground shake. The narrator didn't mention losing the tail gunner. That would make it interesting. Always be given priority at the airports.
The Air Force right now is flying everything they have until they break. That 2050 limit is actually the point at which engineers have stated that the majority of airframes will need significant structural repairs due to the stress of flying. The B1 is being flown under similar conditions, though they're only expected to last until 2040. A contributing factor is that the Air Force only has around 70 long range strategic bombers mission capable at any time (a rough estimate from public releases) and they need them all for deterrence, routine missions like Freedom of Navigation, or urgent missions like air support. That's 70 aircraft including the entire fleets of B52H, B1B and B2. The Air Force wants a fleet of B21 Raiders to take over that entire role, but it's a stealth bomber like the B2. Only 60% of B2s are mission capable at any given time, so is the B21 is just as reliable they'd need 120 or so aircraft. That doesn't sound like a huge deal when Boeing is pumping out 787s at 2 per month (120 in 5 years), but the Northrop Grumman factory struggled to produce 2 B2 bombers per year. That means that they need to keep their old planes around as long as they can for the B21 factory to pump out enough planes to replace the old planes. Otherwise there would be a gap of a few years where they'd have to curtail missions due to insufficient planes.
Cool video, but: - seats weight should be counted, as well as the weight of other systems dedicated to passengers, like sound insulation or oxygen tanks. - a passenger plane needs a lot of cargo room inside the cabin, as well as in the belly of the plane. - wing spars penetrate into the fuselage, vastly decreasing space and usability. - seems like fuselage tapering wasn't considered. All in all, it might be able to carry some 100 passengers. As much as the Boeing 737-100, which however has an empty weight of 28 tons, against the 83 tons of the B52. Zero chances that it could become a commercial plane. Even as a recycled plane, its fuel consumption would be unacceptable.
To add: 80kg is too low a number per passenger, unless they're happy to fly with no baggage. 100kg per passenger plus baggage is a normal rule of thumb figure to use.
If the B-52 was converted into a passenger plane, its transformation would be similar to the Tu-95 when it was converted into the Tu-114, where the aircraft's body was widened, and the wings were lowered from an anhedral configuration into a dihedral configuration like other passenger airliners.
If you watch one fly observe the wings any time they have a decent load those wingtips go up about 18 feet and it has dihedral just from that. When the wing tanks are empty and the plane is at rest on the flight line, the wing tip landing gear is about 5 to 6 feet off the ground. If they did what you say, they wouldn't be even similar to the B-52 as the look is so very distinctive. There's nothing else in the air anything like it.
@@shaider1982 I learned it first from watching heavily loaded B-52s take off from March AFB before it was demoted to an ANG base. Another fun watch was watching a heavily loaded group take off one after the other in a MITO (forgotten what it stands for) takeoff where one starts to roll as one is halfway down the runway and one is climbing over the end of the runway at a thousand feet or so. The last ones tend to wobble a lot due to the turbulence from the planes in front of them. Then another interesting sight was watching them lift off of Guam's runway and then drop down out of sight below the cliffs off the end of the Anderson AFB Runway only to see them struggling for airspeed and altitude as they come back above the horizon of the cliffs, maybe 10 miles out.
There were plans for a passenger version of the Handley Page Victor. And the Lockheed Galaxy originally started out as a rival to the Jumbo Jet. And there a number of others. The Avro York was a civilian version of the famous Lancaster.
@@sundhaug92Sorry your right. For some reason I was thinking the two were rivals for passenger transport rather than military transport. I think it is probably because the 747 was such a success in the passenger role that in my own mind I was thinking that is what it was designed for. It's somewhat ironic that the 747 is now being contracted to transport military supplies.
@@bigblue6917 Even funnier when you consider that the passenger-version of the 747 was supposed to be a temporary solution - it was meant to be replaced by the SST 2707 in that role and then rebuilt to carry cargo
The same for the Avro Vulcan and the Vickers Valiant. Of the two, the Avro proposal went furthest as the Atlantic - a delta-winged 120 seat transatlantic airliner. The government decided to go instead with the Vickers VC-7/V-1000 which would have been a four engine turbofan that outperformed the then far-off Boeing 707. The prototype was 90% complete when the entire project was cancelled in 1955.
Curious what you could do with a C-5 Galaxy. It almost looks like you could make a triple decker, and its weight capacity is around double the B-52. Granted, it doesn't have great range, but it might be nice for a JFK-LHR flight.
@@sunshine135 My thought too :D I know that concept and i really think they should have gone forward with it. I don´t think it would have been so successfull as a passenger-only aircraft, but as a combi aircraft or civilian freighter? Yes, there would have been a market. I think it would have been perfect to fit in the same market that´s held by the Ukrainian AN 124´s. That probably would have been an option for Lockheed to get them out of the shitty situation they were in the 80´s and 90´s.
@@joesheridan95 Antonov design team had a project of converting An-124 into An-418, a mid-range carrier of up to 800 passengers. The project got cancelled in early 90s due to lack of funding, when the Soviet Union dissolved.
@@alexandersulpovar8595 Yeah i heard about that.... i am glad for that end of the cold war, but i feel bad about all the good aerospace tech that humanity has lost due to lack of funding. Newer versions of the Antonovs, Energia, Buran.... it´s a shame that all of that got lost for good when you don´t look at it from an american, european or russian perspective, but from a human perspective.
On the bright side, the B-52 is getting new engines and a technology update of some sort, so more environmentally favorable and remember, the B-52 came off the drawing boards in 1952. So, it’s 71 years old already (give or take) and an amazing, iconic airframe already. Would love to see it in American Airlines livery anyway. Thanks for the great video.
The B-52 has 8 low bypass turbofans. They built it with 8 engines for redundancy, but it's incredibly inefficient. If the USAF is paying, it's not a huge issue, but commercial airlines wouldn't want that.
The only plausible way they could have made a B-52 based airliner would have been to use a different fuselage design. There were a lot of airliners based on bombers, not just the Tu-114, but they all had wider fuselages. But Boeing decided to make a passenger/tanker design from scratch instead.
Boeing developed the 307 Stratoliner alongside the B-17, but it had a larger fuselage in order to accommodate passengers. I believe that it was the first aircraft with a pressurized cabin, before the B-29. Igor Sikorsky, on the other hand, intended for his 4-engine bomber to be a passenger plane, however some jerk shot some Archduke in 1914 and it was quickly re-designed as a bomber. I guess it made sense in the early days of aviation, not so much now.
Loved the imagery, nice job making the civilian Buff. Lot's of commenters have mentioned the placement of passenger seats where fuel tanks are located as being a showstopper. I haven't seen any comments on the landing gear. The outrigger wheels on the wings are nearly 150' apart. The Buff requires a 200' or wider runway AND TAXIWAYS. The tandem lading gear design places a lot of weight on a relatively small footprint... Buff runways needed to be built to handle the more concentrated loads, especially in the touchdown zones. Many commercial airports do not have the runway width or strength to support routine Buff operations. In my days as a Buff pilot, I got to squeeze a Buff onto some runways for airshows for a "one time only" visit. We had to transfer fuel so one wing would be heavy and we could taxi with one outrigger wheel about 6 feet off the ground.
You forgot to mention that a big part at play for the long range are the huge fuel tanks in the fuselage. Add this, and you might have enough room for maybe 50 passengers ^^
Considering that most of that B-52 upper "passenger" deck is fuel tanks you might be able to move some of those tanks to the lower deck. Your 50 passenger estimate could even be optimistic, since that upper deck might still need to be 50% tanks to get the range with the seating being a combination of 1x1 seating in First and tight 2x2 seating for Coach. The passenger experience would be like spending 10 hours in a CRJ. This proposal shows strong indications of cranial:rectal inversion...But look at the views.
As someone who works in the airport. You would need the whole bottom part of the plane for cargo (luggage or actual cargo) and you can convert part of that for fuel as well like what the A321 do for longer flights. So maybe you can get 1 row for passengers and bottom for cargo. It would be a narrow body (1 aisle) so the cargo would be lose. Unless you build in a moving system to have cargo containers to be used
Loading cargo as usual, open bay doors to drop it... Extra points for doing it before arriving in airport... "Passengers of strangelove airways... Please pick up your luggage on interstate b53"
Don't forget the wingspan is far too large for most airports. it also needs little wheels on the edge of the wings to stop them from scraping the ground.
As for your double deck idea, that wouldn’t work either. You might as well just leave it for baggage and cargo. Otherwise, you’d likely get a lot of angry passengers at their destinations.
@@jebeda Not going to ever fly again unless i win a couple of billion in the lottery. The indignities they inflict on passengers is so bad I wonder why ANYONE would fly commercial ever again.
@@jebeda Believe it or not, that would actually deter airlines from buying. You make a valid point but, Airlines aren't expressly going out of their way to piss you off.
keep in mind that the B 52 has just received a new lease on life with the new Rolls Royce power plants that are in approval and production. Adding creature comforts to this very capable air frame would not be a big deal for Boeing as they have been the premier passenger airliner manufacturer for many decades. Using more modern materials and techniques, this transition to civil service is not that big a stretch.
The hangups would be how space is used inside the B-52. Such as landing gear and fuel storage. Those are part of the design of the plane and maybe can't be changed very easily. Also pressurizing, heating/cooling, and insulating the entire plane. Basically you'd end up designing a new aircraft.
Yes, but as there are no props, no need to extend the landing gear. Just put the fuselage above the wings. But let's forget it. If 4 engine planes are out of equation now, it goes double for 8 engines...
A few issues: 1. The weight-calculation you did ignores the weight of seats etc 2. Boeing already made the 377 Stratocruiser, based on the superfortress 3. The B-52 uses low-bypass engines, which have terrible fuel-efficiency compared to modern high-bypass engines
@@j.michaelpriester8973 I rode a few cross country flights in KD-97s that were fitted for VIP travel. I was going TDY and was very definitely not a VIP but it was going where my orders said and it was pretty empty so away I went. We left Ellsworth AFB in South Dakota one day and flew straight back to March AFB (at the time, 22nd bomb wing headquarters) and about 10 minutes after we left a KC-135 also left but was headed to Maelstrom AFB in Montana where it made a stop to offload and onload something I never found out about, but it then took off and headed for March AFB and got there 2 hours before we landed in that KC-97. But it was a pretty comfy ride.
The B-52 is actually not as large as some think it is. But I was amused, one day many years ago while waiting to catch a Delta flight, by a somewhat inebriated individual who had just stepped out of an airport bar who insisted that the 747 is the civilian version of the B-52. He was one of those know-it-all drunks who got smarter with every drink! They say you can't argue with a drunk, so I didn't try.
Not a good idea cause besides to its small size compared to other commercial passenger aircrafts, the landing gear takes up a lot of space inside the fuselage.
Another precedent was the first Soviet passenger jet, TU-104. "The design request was filled by the Tupolev OKB, which based their new airliner on its Tu-16 "Badger" strategic bomber. The wings, engines, and tail surfaces of the Tu-16 were retained with the airliner, but the new design adopted a wider, pressurised fuselage designed to accommodate 50 passengers."
I have always wanted a C5 Galaxy half buried in a field of grass in a clearing in woods, an aircraft as house. I worked on C5's and they are BIG inside. It would be like the old New England house with several attached barns and outbuildings. And....the tail would make a really cool deck, high over the field by 60 feet. Four Sikorski helicopters in harness to deliver it. Nice
I worked on the C-5 from 1978 until 1981 at Dover AFB in Delaware, and at the Rhein-Main AB in Germany. You speak of a deck on the top of the tail. One of my regular duties, as a radio specialist, was to maintain and repair the flight recorder, which was located on top the tail, on the outside. Can you spell "acrophobia?"
Wings would have to be lowered to somewhere around the red line or lower for the design to work. The fuel consumption would be amazingly horrid, would be a good cargo craft for FEDEX lol
The other one to look at was the Convair B36 "Peacemaker" and it's orphaned derivative the XC-99.... which was planned as an early twin-deck passenger aircraft, if not for the delay in suitable turbo-prop engines, and use of Pratt & Whitney R-4360-41 Wasp Major 28-cylinder radial engines, in pusher configuration.
The center line fuel tanks would take up most of the upper deck seating area along with the wheel wells. Take the fuselage fuel tanks away and you lost your range.
Passenger aircraft don't need such huge range to be useful, as they can stop and refuel. It costs time, but if the benefit is lower operating costs or more passengers its worth it. Bombers don't have that option, they have to be able to get to the target deep into enemy territory. A bomber can't just stop in Murmansk and say "Fill 'er up please, 300,000 pounds jet fuel on pump two, we're on our way to bomb Moscow!"
When you look back at aviation history's , nearly all the manufacturer have converted bombers into commercial use. I believe the Avro company had considered turning the Vulcan B.1 bomber into a passenger carrying plane, there would have been some major changes to the airframe, the idea was drop due to cost.
It's a nice idea to think about, but when looking at passenger comfort the first thing that came to my mind was the fact that the wings would shadow most of the windows. Technically you would be flying in a tin can. Plus, the fact that the airframe is built for de pressured flight, would mean conversion to a pressurised version to be costly. It would also be uneconomical considering the fact that the wingspan is too high. Like other people said, the bottom deck would just be a waste due to the gear well. Might as well use it for fuel and luggage?
Even though there are some high wing airliners, the problem is that in a ditching at sea, the wing is the part that floats and tends to put the fuselage underwater. The "Miracle on the Hudson" for example would have a different and far worse ending with a high wing.
Don’t forget bathrooms and galley at the front, middle, and back. Also, those seats at the outside edge would have no headroom. You’d likely need to lower the seat deck down to also allow for overhead bins making it only one deck of seats.
The 787 dreamliner is about the same size and only uses 2 engines. Which is a lot more efficient. You couldn't put two big engines on the B52 without redesigning most of the plane to deal with the asymmetric thrust should an engine fail leaving only a single engine left.
Unlike other bombers, the B-52 is very available to loose civilians at typical air shows! I've walked inside the bomb bay at the Goldsboro NC air show two times! It is remarkable how thin the fuselage is! And at the same show they had a KC-10 refueler, which is similar in dimentions to a modern wide-body passenger airplane. Wow it is much higher off the ground, much wider, more intimidating in fact! Of course it was designed like 30 years later, and that's still like 40 years ago.
The KC-10 wasn't just "similar in dimensions" to a wide-body airliner, it was literally built on the airframe of an existing wide-body airliner, the DC-10.
Well, tu-114 had entirely new fuselage 4.2m wide, 50% greater in diameter than tu-95 and being the widest single aisle airliner ever))) and it was like 7m longer than tu-95. And wing area was enlarged . And it was double decker, with a bar and kitchen on the lower deck behind a centerplane) and during design, 4.8 and 5.6m fuselages were conscidered) Btw, you forgot that centerplane would take like 20-30 more seats on b52s upper deck
An interesting thought experiment for sure. Certainly wouldn't make any sense in present day, but is interesting to consider if Boeing had made a passenger version of it way back in the '50s, before they began development of dedicated passenger jets as the Dash 80 and subsequent 707 (which incorporated a lot of knowledge they gained from the B-47 and B-52 projects). The Tu-114 wasn't the only example, around that time there were tons of bomber-to-airliner developments, such as the Boeing 307 based on the B-17, Boeing 377 based on the B-29, Avro Lancastrian based on the Lancaster, and many others. All of these had different fuselages from the bomber versions, basically used the systems, engines, wings, tail, but with a wider fuselage. A B-52 derived airliner would probably have the same wings, tail, engines, maybe cockpit, but a different (wider) fuselage and likely more conventional landing gear. Though the 367-80 flew only two years after the B-52, was clearly already in development, so it seemed Boeing already had in mind to go that path rather than a bomber-based design. The 707 wasn't as large or heavy as the B-52 (using half as many of the same engines), somewhat lower weight, much less range, but surely far more economical to operate.
It was also very troublesome for maintenance crews and suffered some serious accidents. It seems that the engines were too powerful for the propellers.
Many airliners were based on bomber designs including the successful double deck Boeing Strato cruiser based on the B-29 it flew a decade before the Russian airliner. There was even an airliner version of the B-36 the Convair XC--99 that flew for the Air Force during the Korean war the 400 passenger plane was ordered by Pan am and TWA but orders were canceled because the market of the late 1940s could not support such a large plane.
This thought exercise makes some sense and I am sure Boeing did examine it. There were airline versions of the B-17, B-29 and conversely a bomber design proposed from a 707.
And the 707 was developed in the E-3, E-6, and E-8 communications and surveillance planes. The 707's predecessor, the 367-80, was also developed into the KC-135 planes.
When I first saw your subject. I was totally in the WTF mode. LOL. You nailed it perfectly! I pushed that beast around the skies for decades. The fact that you got the wheel wells and gear stowage nailed was fantastic! Very well done Sir! Oh yeah..... Comment.. Big crew cabin?!?!?! Uh, you cant stand up in that thing. the only place to stretch is the ladder between decks. Your channel is awesome, keep it up!!!
I would go the opposite route and make it an all luxury liner with private lounges, have a bar up front just behind the entrance with stairs to get to the upper deck, have an elevator to access a kitchen in the upper deck ahead of the bar. That way your weight distribution stays more even.
It wouldn’t work because of the high wing. There are internal structural components connecting the two huge wings; they’re not just tacked on to the side of fuselage. So no passenger seats where wings contact body, at least on upper deck. And as you said, the bottom deck would be interrupted by the huge landing gear that retracts into main body, unlike low-wing designs that can use wing for some of space needed to stow landing gear. All modern airliners have a low wing. I noticed that actual Soviet plane was redesigned from high wing bomber into low wing airliner.
@@EkimDyslexia There is redundancy from having more engines in a long-range military aircraft. I wonder if replacing each PAIR of engines with one larger engine was considered for the refit. Probably not viable because it would change dynamics too much; might as well design new plane.
@@ken1w haha..from REGULATIONS OF 4 engines to cross an ocean to three to two now..think you are living in the past? ..GEE f16 IS STILL USING one ENGINE IS IT 50 YEARS LATER?
@@EkimDyslexia You’re comparing fighter to bomber? Gee, more recent bombers (the other ones in current service), B-1 and B-2 still have four engines. B-52 is an OLD aircraft with capabilities U.S. Air Force wants to keep in service. Hilarious that you believe B-52 can be retrofitted to use ONE huge engine. Four maybe, with one engine replacing the pair on each existing pylon. And FYI, a key reason the next replacement Air Force One planes are still Boeing 747 (no longer produced as commercial planes) have four engines is for redundancy, so it can keep flying reliably if an engine or even two fails during flight.
Many surplus WW II Lancaster bombers were converted to passenger planes! A great video based on an interesting idea! I would like to fly on passenger version of F-16 (or a military one)...
The B-29 Superfortress was converted into a cargo plane called the C-97 Stratofreighter which was then converted into a passenger plane too, aka the 377 Stratocruiser.
I think your estimate is still too high. You're probably lose *more* than 100 seats between the wheel bays and the cargo hold. But more importantly, there are structural elements that run between the wings at the top of the fuselage that would most likely be too low to comfortably fit seats under. Then add to that the space taken up by the stairs needed to navigate the now multiple points where you'd have breaks in each passenger deck, plus rest areas for the crew (this is supposed to be a very long range airliner, after all), and you *might* get 200 people on board if you cram them in.
Much more loss of seats - the tops of the seats on the top level are outside the fuselage - it shows that clearly in the animation. And can't just copy the same width and aisle to the bottom level because the floor is much much narrower.
Sounds like instead of two passenger decks, there should be a single passenger deck that can squeeze in between the top of the wheel wells and the fuel tank. The space under the passenger deck that's not taken up by the wheel wells would of course carry cargo and luggage. Not sure what you'd do with the available space above the passenger deck though. Of if there's not enough vertical space between the fuel tank and the wheel wells, have the single passenger deck snake up and down around them, which will of course cut into seating area since the level change areas are likely to use stairs, NOT completely vertical ladders. And that's going to make serving meals and refreshments to passengers a challenge since I doubt a food cart could navigate stairs.
Not to mention needing R Med doors if you are going to be flying over 189 your gonna need those which takes up more room and considering the lack of over wing exits would be an engineering nightmare
Fun fact: The Boeing 747 was originally designed compete against the C-5 to replace the C-141. Boeing was still able to convert the 747 to passenger use when Pan-Am said they wanted a larger passenger plane.
2:09 killed me lol such much truth in that... makes you worry about the up coming war when half are population cant even set idle without breathing heavy lol to they are the ones always acting tough.. like what ya gonna do boy? set on me? got to catch me first... take 3 steps back and they pass out trying to get at ya. Wasted all the energy trying to pry themselves out of the lazy boy lol
Convair had some passenger designs for the C99, the cargo version of the B36. They designed both land and seaplane variants. Also a nitpick: I think you would also lose passenger space at the wing root. All that inconvenient structure for the wings.
We are now in the age of twin engines for airliners. While you could design and build an 8 engine B-52 like airliner, good luck getting any airline anywhere in the world to buy one! Passenger variant versions of most all larger bombers and transports are proposed, they seldom get passed the paper drawing phase.
they could place only 176 passengers on upper deck, while 6 seats on any part of the plane were removed for the stairs to be placed and there would be 170 people on board, and the deck down the stairs would have entertainment, food, drinks and all that stuff. Oh and also put pressuried walls behind the predetermined walls! What do you think?
