This Engine Will Change Aviation Forever 

Yessir. glad you pointed that little fun fact out. I flew G's and H's. F & Ds? Wow, Old School for sure. Nice.

@@davidschiffer4448 Old school for sure. Flew Fs at Castle in 72, D's in Thailand and Guam in 74, and G's at Castle, Beale, Seymour Johnson, and Guam (Combat) from 72-78. A/C from 76-78. They did correct it later in the video. Kenneth P. Johnson, Lt Col, USAF (Ret)

I understand the new engines will reduce cruise speed significantly.

@u2mister17 To my knowledge no. The new engines might change some aerodynamic characteristics and the maximum Mach but cruise Mach should remain the same.

@@kennethjohnson6619 Thanks for getting back to me. It is not a well talked about detail. But you know the older turbo jet engines are much faster than newer design turbo fans.

Actually, the change first occurred in 1961 with the rollout of the H and the TF33.

Turbofans are much more efficient. If you ever watch early 60's era movies where they show a commercial jet you'll notice the jet engines are very long and thin. These are turbojets. The turbofan adds a big fan at the front that increases efficiency bigly. Those engines are not long pencils but more like stubby Coke cans.

@@protorhinocerator142 True. Like the cigar shaped engines that lasted so long on the 737 - really made them stand out for a time in the 70s. Also why large, slow aircraft all moved away from internal engines to wing mounted.

@@smgdfcmfah I never thought of that but yeah it makes sense.

Everything Changes EVERYTHING. so much noise . . . . . .

Yeah. I was waiting to hear just how such a niche application of an already-widely-used engine is going to change aviation forever. Such a title detracts what is otherwise informative and interesting video. They shoot themselves in the foot when they do that.

the engine has evolved over the years, it's not a 30 yr old engine. but if I change the subject to Boeing 737 it has not evolved well and is a baby killer which the B52 was accused of being a number of years ago.

Thank you, sir. Much appreciated...

@@paulmorgan8254 , based on just one article that I’ve read (online), after the second B 737 Max crash and subsequent grounding, the reason that Boeing in general, and the 737 in particular, has gone downhill is directly related to them buying McDonnell Douglas a number of years ago. McDonnell was going downhill because of bad management so when Boeing bought them, that action put them inside of Boeing, so that they could do for Boeing what they had done for McDonnell Douglas. Specifically, Boeing had always promoted aeronautical engineers into management, so that whenever engineers had questions, they could simply ask people who had good answers. After the McDonnell Douglas people got promoted/ moved into those senior positions, the engineers kept asking them questions. The difference being that the McDonnell Douglas people were NOT any type of engineer. They were accountants and such. So, with so many of upper management now being other-than-engineers, and tired of being embarrassed with not knowing the answers, they moved corporate far away, to the Morton Salt building in Chicago, the article said. So now upper management can hide from the engineers, but their lack of expertise now shows up In defective products. Actually, it seems that I heard that now, upper management is looking to move to some third location. Probably somewhere where they won’t get shot at during their commute.

“Every airline doesn’t own their Rolls Royce engine”? Are you sure about that, because I’m pretty sure that’s not true in every case!

And rr remotely monitors the engines, which lead to them telling a quantas a380 flight to land ASAP as they detected potential failure warnings. Of course that monitoring would not exist in military engines, at least not remotely whilst operating.

@@bash102 im fairly certain that was not his point

I read vertical stab was originally supposed to prove trim, that’s why the rudder is so small and the need to keep the 8 engines.

The B-52 wing is rather flexible and four larger single engines would have reduced ground clearance greatly; that's my understanding of why they went with these

I remember a discussion during B-52 initial training at Castle AFB, about a 1970s attempt at updating the B-52 engines. The issue with going to 4 engines was that the systems on the B-52 include 4 generators bleed air to/from all 8 engines and hydraulic pumps on 6 engines. The hydraulic systems were not exactly fully redundant, more like losing one pump wouldn't lose all spoiler control, just some of them, so with 4 engines, you could lose 2 hydralic systems with the loss of a single engine, which might be extremely dangerous. Of course,, this discussion was back in the 1980s, when I did my initial B-52 training, and nobody imagined that the planes would still be flying in 2023. Heck, in 1983 the Gs and Hs that were the only ones still flying, already looked like they were one foot in the grave. So the re-engine program was dropped, for 40 years. We would have saved a bunch of gas and maintenance had the pentagon paid for the upgrade back the instead of today but, gas was cheap and there were piles of J-57/TF-33 engines and parts sitting in retired 707s and DC-8s.

Was thinking the same earlier😮Makes sense, obviously weight distribution should help the climb.

I was going to say the same thing. Having a 10,000 lb weight shift in 20 minutes at the tail of the plane would have caused an unacceptable CG test during take off and early climb out.

How is it a spaceship?! That’s an odd description as it is dependent upon aero foils and atmospheric jet engines and has no ability to achieve escape velocity.

@@rcpmac You are being too literal is all.

@@rcpmac takes up a lot of space

I lived in Redlands with my family from ‘56 to ‘59, then occasionally we went back and forth to there from our new home in San Diego county. For one period I remember seeing March just packed with parked B-52s, but I can’t remember exactly when. Do you remember the time frame?

You're our enemy today, how about that then, Yank? Be gone.

Yes the Saturn V was really an incredible achievement, back in the day when the US was such a great country. I was just a 4 year old kid then but I saw the Saturn V launch on Apollo 10. I remember the feeling of pounding on my chest as it rose into the sky. I also get a bit misty eyed thinking about those days... :)

@@fishbike9103 My ex BIL was in the Air Force, stationed at Austin, TX. My then wife and I drove from CA to visit her sister and our new BIL. He was kind of a rebel, never paid much attention to any rules......we went to his base on a Sunday afternoon when it was lightly staffed. A B-52 was parked next to some office buildings....noone around, so he and I went exploring...up to and inside of this B-52...I even sat in the pilot's seat. Also, don't recall just how we got on top of the craft itself, but walked along the main fuselage all the way back to the tail...that tail fin looked like it was 50' tall when standing right beside it. He also 'borrowed" a really nice pair of four legged jack stands, returned to the base about midnight......the guy 'on duty' was asleep at his desk, my BIL went over to a set of jack stands on the floor, picked them up, loudly clanged them back down onto the concrete, saying to the guy on duty, "I brought those jack stands back"....to which he replied, "Yeah, OK!" For years I ran an auto repair 'on the side' and those stands have had a lot of use...much more heavy duty than the standaed three legged ones.....and, over 60 years later, still have them. For 35 years I ran huge rotary kilns which ran 24/7, and would often go 18 months without shutting down.....I had one week end off/month. Anyone who thinks the graveyard shift is just another eight hour period of time needs to work it for a few decades....like I did. BHE

Sorry to spoil your eardrums, but in the RB211 development I supplied the real time data acquisition computers to RR Derby. The accustic chamber was unnerving to work in (you could hear your own heartbeat) in complete contrast to the bearing testing labs.

Airframe age is one thing but how many total hours/cycles on the average? I’m sure Boeing has published an aging aircraft inspection program that should keep the B52 airworthy for a long time.

The saying is that when the last B1 goes to Davis-Monthan, its crew will be picked up in a B-52. Same for the B-2.

We have had a wing failure previously i.e. the fatal crash killing three on the BUF from Seymour Johnson over South Carolina in September 75 but that is the only one I know of. I later flew with the IP who ejected from the CP seat and he told me much of the details. That was not wing spar but a wing separation during a fuel leak between pod 3 and 4 flying back and shearing the horizontal stabilizer.

Refit to 4 engines is a bad idea. Loosing two engines on the same pylon is a serious situation on the B52. If the aircraft is fitted with 4 large engines, loosing one engine would also pose a threat. The pylons are old and can not take a lot of extra thrust.

@oldmech619 Darn right stupid for a lot of reasons. They looked at it and it was not feasible.

I think so far its "only" 3 generations. But if the B-52 is as long lived as its planned, a 4th generation and maybe 5th should be possible.

@@Coyote27981 If a Major or Col was in their 30 or 40s when they flew the first 52s or 130s they could have a son in flight training, giving another generation.

Be patient.

The Merlins helped win the war!

Made by Americans under licence (Packard I think) and improved by using modern technology. A Brit.

@@eddyd8745 yes it was made under license by Packard motor cars .......just ask a man who drives one ....lol

Rather the merlin was suggested for the p51 to fix its poor performance with the original Allison engine. The merlin had been in use and development in Britain since the mid 1930s by then and was rather well developed. Of course without the merlin there would not have been a Britain for allied forces to launch from later in the war as it was crucial for the battle of Britain.

@@bionicgeekgrrl... the Hawker Hurricane had more 'kills' than the Spitfire, but you might well be right.

Best comment!

A good one!

Considering the total diameter of a GE90 turbofan engine, that's not really that impressive. One couldn't simply use it on a bomber such as the B52, considering the distance between ground and wing's surface

The GE90 is a giant too big for this plane. So you could say it's 8 in 1

@@nunomc2815 I wasn't suggesting that it could be used on the B-52, I was just marveling at the thrust today's turbofan engines can produce when compared to early turbojet engines.

@@FunnyVideoCollector Ya the TF-30 along with many others would say other wise...

​@@FunnyVideoCollectoryou should specify high bypass, plenty of fighters fly at supersonic speeds using low bypass turbofans. F15,16 Typhoon, F22.

The depot level service programs for most USAF aircraft of the era were designed to keep them flying forever if needed. They can remanufacture and replace any part of the structure, wiring harnesses, etc. that they need to. I'd wager that the B-52s flying today have very few original parts still on them, for critical structural parts like wing/fuselage joining areas it's a safe bet that none of that factory original. It'd be really cool to see their maintenance and repair history made public record if they're ever retired. Physical copies of all the mx logs for a single in service B-52 would probably take up a few bookshelves at least, that'd be an awesome addition a collector's library!!

​@@DHEFDAWG'Trigger's broom' basically.

The Airship of Theseus.

Im sure it’s still safer than a new 737 max

They did. B-58, B-1, B-2, B-21. But they haven't come up with anything better or more capable or more versatile that can fill its unique capability suite.

However it left huge BUFF's in the ground when the bombs went off!

@@kenhurley4441 So?🤷‍♂️

Crewmembers like me (A/C) refer to it as the BUF or Big Ugly Fu__er, although it is hardly ugly.

Nah, it’s Fugly compared to a Vulcan. 🇬🇧

@@Bob10009 They are both good looking aircraft, but as bombers practicality is what counts. That's why the B52 still flies. The Vulcans range was limited (look at the silly, imprecise raids in The Falklands!), it couldn't carry anywhere near what a B52 can, the crew conditions were cramped and cockpit visibility was woeful!

Still quite a bit of use for b52s once airspace is uncontested, especially looking to the pacific. A bomb/missile truck capable of crossing the pacific at a relatively low cost would still be extremely valuable.

In the Gulf War in 1991 the B-52s were launching long range bombs from thousands of miles away. They'll do the same thing in any upcoming war. There's no need to put them in danger.

@@jimdigitalvideo They were cruise missiles to have that range, but agreed!

@@ColinDyckes I was wondering what they were called when I was making the above post. I know most bombs are glide bombs, which means short range, but not all. I also know most missiles are air-to-air. I knew B-52s were bombing targets, so I went with bombs. I was half-right. 😁
