It actually astounds me that this thing exists AND flies. Its just something youd expect to see in some dystopian 70s scifi movie but nah, it exists and WORKS in todays reality. What a magnificent piece of engineering and what it must take to build these things. One of the coolest things to exist in aviation probably ever.
@@endsdio4834 it was 20 years ago, not today. Unfortunately many had to lose their lives along the way for us to learn those lessons, but we have learned them and it is a very effective machine
When Typhoon Haiyan wreck havoc in our Country (Philippines) which almost brought Us to our knees the US immediately dispatched its Fleet along with these Angels of Mercy....these Ospreys along with Blackhawks delivered the much needed help to the most affected area...it has transported thousands of people especially those who needed medical attention....words aren't enough to Thank those Pilots and Air crews who partake in those daunting task but God will surely bless them all....
It is hard to describe how it feels to stand close to this aircraft when it is running. You literally feel the vibration and air pressure through your entire body. I can also tell you that this is a very complicated machine that requires a lot of maintenance. It must cost a fortune to keep these things flying.
Civilian here, and I'm amazed by the Osprey. It's a mix of old rotors and new VTOL capabilities. Some people may like the angles and curves of the F-22, but I find the Osprey sexy. Of course, I find the A-10 Thunderbolt sexy too and a lot of people thing Hogs are hideous. All I can say about that is that function has its own beauty.
SpazzyMcGee1337 • A10's are my favorite planes; have been ever since I first saw one. They are so unlike other planes; so ugly they are cute. One life-saving machine! For a fighter I still love a F-15. My husband loves the old F-14 Tomcats despite being a US Airman for 20 years. He likes Ospreys too. Maybe he should have been a Navy aviator instead? .
Stephen Ward that's nothing. I've seen about twelve, each in three aircraft formations. One of the formations was the missing man formation. I've also seen a few chinooks, Blackhawks, two Sea Stallions, and a ton of C-130s.
Was able to ride in one of these before my military career was over.Pretty scary, I felt much more secure flying with a Blackhawk and a Chinook. Never got to fly in a huey though.
Stephen Ward Hu your english is not perfect unfortunately. Well.... happy new year everybody! This is a HELIPLANE, WHICH MEANS THAT IT'S A MIXTURE OF A HELICOPTER AND AIRCRAFT.
I have these flying over my house often. The whole house shakes much more than a helicopter would do. I can tell when they approach by their incredible thumping sound.
Either engine powers both rotors. Engines originally designed for horizontal operation so some oil bypasses the labyrinth seals when static and vertical. The growing pains have been resolved except for making fixed wing pilots into V-22 pilots that don't understand helicopter aerodynamics as settling with power. This aircraft has recently been integrated into the presidential fleet an that is a vote of confidence. A truly fine aircraft that has set a new standard.
***** Below is link to V-22 in the presidential fleet and colors. The president does not yet fly in it but two are in the fleet. I have been an aviation mechanic, inspector, instructor, factory tech rep, State Dept. Aviation Advisor and safety consultant and I would fly in this machine anytime. www.dvice.com/2013-8-11/image-day-mv-22-ospreys-join-presidential-fleet.
I live out in the middle of nowhere in Texas, and one of these flew over my house about two weeks ago. It was strange, but also really cool to see one flying in person.
I helped build the first 250 fuselages, structurally, including the developmental aircraft. All the holes are class one. All the hardware is Titanium. Built to last at least 50 years. Some of what it is capable of I wasn’t even allowed to know about. There are antennas that no one was allowed to even look at and they had trashcan liners on them.
I remember being young, at an air show. They had the propellers going and my family were inside. I thought it was going to take off but I was not one bit afraid, I just sat there and waited. It was the worst moment of my life when they asked us to get out so they could do their part in the show
The connection shaft is a security feature of the v22 in case of one engine failure . Due to the high torque needed for this propellers (for the VTOL feature) it's more reliable to have a very strong gearbox to de-multiply jet engine speed to prop speed that to have shafts and gearboxes under high loads . Also, in the VTOL it's better to have weight in the extremities of the "wings" , that act as counter weights directly under the vector of propulsion , plus the heat signature it's reduced.
Never ceases to amaze me the technology engineered into these machines, that they can even fly!!! God knows that cost has been high, both in dollars & human lives!!! God bless them!!!
V-22's osprey transmission are huge compare to its rolls-royce ae1107c liberty engines. In fact most of the nacelle is transmission and generator. Center top of the wings holds a lot crucial components including the mid wing gearbox, APU, and 2 generators.
Kind of cool how it shows the two engine transmissions are interconnected. He starts the right engine first, but both rotors begin turning. Then he lights the left engine after signaled by the ground crew.
Very impressive aircraft. I see them fly into Burbank , California airport about 1-3 times a month. I see them flying with the two Marine One helicopters fly into Burbank every now and then as well whenever the President comes to town. Very cool sight to see the Presidential detail. There is usually two Ospreys in front then the two Marine One helicopters and two more ospreys flying in the back.
They are connected by an interconnecting driveshaft system so that one proprotor isn't spinning faster than the other. They're mirrored because of an extra idler gear in the proprotor gearbox.
Well, I wouldn't be surprised. Know a couple flight engineers that went on rescue missions in Yemen. This platform was top choice for the SF teams doing the extract6.
@Cinderblock1775 No, it was a little chilly that morning and they do typically have a fair amount of exhaust when they start. The 2nd engine has just as much smoke, but it's more dissipated by the rotors
The engines, Rolls-Royce AE 1107C have separate turbines for driving the compressor respectively generating output power. The power turbine can spin freely without the rest of the engine (compressor and first turbine) turning.
Please, can we use footage from your RU-vid channel for our videos about military cars, trucks a other machines? We tag your channel as a source ,... thank you. :)
i wish all people were like you on this thing.... it was a god question and now i know somthing i never knew, and that really cool. thanks for your answere and thanks to the otherguy asking the question. This truly is a fastinating piece of enginuity :)
From what I've read about these planes when they were first introduced there were quite a few flaws that resulted in accidents & deaths... & many within the military chain of command tried a few times to have this particular plane scrapped from service due to it's questionable service performance...
The smoke you see is oil that has leaked from the engines because the aircraft was left in flight ready too long. Osprey's engine were not made to stay vertical too long so they leak a lot. As for its heat signature, its pretty low because its IR suppressor takes in air and mixes it with exhaust.
As others have said, these things are loud. I live in Milwaukee and I was at the Layton Ave observation lot one Saturday or Sunday with the scanner as I have been doing now for decades now. There were 4 of these loading up so I waited and finally they fired up the engines. I had the car windows closed and the engine off and yet my car was shaking like crazy. That was neat. This was a few years before I had a smart phone so I didn’t have a video. Oh well I still got to see it.
V22 Osprey is the coolest looking plane I've ever seen - it's a damn shame they're so crash prone. Hopefully in the future those issues will be resolved.
It's from sitting in a vertical postion. APU just gives ground power as normal to provide hydraulic pressure for the starters. Hope that helps without too much detail.
The major who "cooked the books" on the maintenance intervals for the whole fleet of Ospreys has been making smaller rocks out of really big rocks in FT. Leavenworth, KS. He was also dis-honorably Discharged from the USMC. Due to his ignorance the "derogatory nickname" for the Osprey became the "Carolina Lawn Dart", as they were and still are based in North Carolina.
The ospreys or v-22 is both a helicopter and a plane, however the blades on the nacelles or not configured for vertical takeoffs but are still capable of hovering for a short period of time but it still needs the runway for takeoffs only but can still land vertically?...
People are arguing wether its a helicopter or a plane. The proper term for it is a Tilt Rotor Convertiplane, airplanes that uses vertical thrust for takeoff and landing then transitions to horizontal flight.
Wonder what would happen if the props got stuck in the horizontal postion and you had to land it like a conventional plane, would they clear the ground?
They will hit the ground but the props are designed to shred or "broomstick" and are supposed to not break apart in to shrapnel. The aircraft has several redundancies to prevent the engines getting stuck but in worse case scenario there is supposed to be safety features in the wing, nose, fuselage, gear and seats that will allow the crew to walk away from a normal runway landing.
Amazing invention....see few of them in Mach loop North Wales...awesome best of both worlds...fixed wing and rotors.. 2:49 aha BP sign powered by BP British Petroleum lol
The engines are started via hydraulics. With these older videos you will see them smoke because the engine drains oil in the vertical position. With new engine crank procedures and modification they don't smoke as bad anymore. Its perfectly normal.
I'm pretty sure both engines need to be cranked to start even if one engine is already running. This is because these gas turbine engines are dual shaft "gas producer" turbines. This means the compressor section is coupled to a high pressure turbine on a single shaft while the rotors are coupled to a low pressure turbine section on a separate shaft (hence dual shaft engine). This is to allow the compressor and high pressure turbine to operate at a different speed than the low pressure turbine. The advantage of this is less need for reduction gearing to achieve desired rotor speed while also allowing the compressor to operate at a much higher speed (axial flow dynamic compressors operate better at higher speeds while the rotors need to be kept at a much lower speed). This also allows for better handing of load fluctuations (compressor and high pressure turbine are free to spool as needed while keeping the rotors and low pressure turbine at the same speed). Most helicopters and turbo-prop aircraft run off this design of engine. If engine 2 is running but engine 1 is not both rotors will turn since they are coupled by a shaft that runs through the length of the wings, but engine 1 still needs to have its compressor and high pressure turbine section cranked over before lighting off. The low pressure turbine on engine 1 may be turning but that is not enough to get the high pressure turbine turning.
i'll take a stab at the smoke and try explaining it (could be right, most likely wrong as am not an expert...) i've read that these have a common gearbox in the centre of the wing, so in the event of an engine failure both props keep spinning. the exhaust plume of the right engine 0:41 is that engine starting up, the exhaust of the left engine at 1:45 is it starting up.
The engines may be connected to the common driveshavt by a freewheel. This keeps the Osprey in the air with only one turbine, but does not waste energy to keep the other engine turning.
I'm pretty sure they start one at a time. The rotors are locked together via a gearbox. You can see the first engine (Stbd) side start first, then the Port engine starts later on. You can see the guy at the front signal for an engine start at 1:24, followed by the smoke as the second engine lights off. Maybe I'm wrong though xD
I believe you are correct. I had forgotten that the engines are linked, but start separately Someone had corrected me earlier....Still this is an impressive aircraft..
ttcummins99 Nasty secret this has actually never been tested (never with a hard shut down). It can't hover with one engine and has never been tested dead-stick landing and yet it was certified? If you lose an engine you have to limp home in plane mode and hope the one engine stays lit. If not the engineers say your dead-stick attempt will be fatal (this is why it was never tested).
It is a marvel just seeing thing in motion... What skill it must take handle a bird like that, I don't know but it is impressive. (Along with engineering, test work, model, sketches, even blue print designers were probably scratching their heads saying "you want the engines where? with this size propeller blades, and pivot... WHY? go back home and have another one on me!!" LOL .... But two manufactures made it happed I guess Bell and Boeing...
Really up to the pilot and cargo. The plane could take off with a heavy load vertically but it puts a hard load on the gearboxes. For the sake of the gearboxes lifespan its easier to drop the nacelles a bit and do a very short rolling take off.
