The US Air Force temporarily banned the use of CV-22 Osprey tiltrotor aircraft due to technical problems

The CV-22 Osprey tiltrotor aircraft are actively used by the special forces of the US armed forces to solve assigned tasks. But recently, the US Air Force Special Operations Command decided to ban their use. This was announced by the commander of the AFSOC (CSO Air Force), Lieutenant General Jim Slife.

The reason for the decision to temporarily ban the operation of the tiltrotor was the increasing number of incidents. Over the past six weeks, there have been 2 incidents with a tiltrotor, and since 2017 there have been four accidents. Now in service with the US Air Force Special Operations Command are 52 tiltrotor CV-22 Osprey. Their operation was suspended indefinitely due to the increasing incidence of incidents. The cause of emergencies is a technical problem, according to Breaking Defense.

The US military describes the problem as "clutch hard engagement." Essentially, the clutch inside the gearbox that connects one of the two Rolls-Royce Liberty AE1107C CV-22 engines to the propeller rotor is slipping for some unknown reason.

Due to the rapid power switching between engines, a situation arises in which the crew is forced to immediately land the CV-22. Accordingly, the use of a tiltrotor in such a situation becomes problematic. The command of the special operations forces reminds that injuries or deaths were avoided only thanks to the high professionalism of the tiltrotor pilots. But the Command cannot risk the lives of pilots and special forces more.

As stated in a statement by the US Air Force Special Operations Command, not a single tiltrotor will take off again until the cause of technical problems is clarified and appropriate measures are taken to eliminate them. In many cases, both gearboxes and engines require replacement after incidents, making them Class A accidents with damage in excess of $2,5 million.

Recall that the CV-22 Osprey has been operated by the US Air Force Special Operations Command for more than twelve years. It is a subspecies of the V-22 Osprey, a tiltrotor capable of taking off vertically and hovering in the sky. It is not yet known whether the problem faced by the US Air Force affects convertoplanes used in the special forces of the Navy and the Marine Corps, where their V-22 Osprey subtypes are also in service.

These V-22s are somewhat reminiscent of the F-35 to me, they have spawned, but along with old chronic diseases, new jambs appear. And the cabbages swelled hoo, but the business is American.

It's a pity ... An hour of flight of this pepelats is more expensive than that of a "penguin" ..
Want to save money?

[hell machine]

They’ll print more, what’s the problem? 800 billion or 900 billion are spent on the defense industry, grandmas are not a problem, so to speak

[Boratsagdiev]

With these devices, everything was known from the very beginning (pluses and minuses).
Given their narrow focus in use, they coped quite well and not bad.
They just need to be serviced more often, which was foreseen.

The text was written by a robot or Google translator, very interesting, but nothing is clear.

I'll even tell you where they got it from - this is the marinecorpstimes website

If one country spanks a child prodigy, while others do not even try to repeat it, this means that the child prodigy is either for a very specific theater of operations, or she is not a child prodigy, but a waffle, like Osprey

[mojohed2012]

The Osprey problem is that, if 1 motor and propeller fail, the second one will not pull out and the death is 100%, while helicopters have 1 propeller, but the engine is duplicated, the ability to survive is greater.
The Americans have seen enough of Avatar, made a child prodigy in the image and likeness - they suffer! And let them suffer!

the helicopter has the opportunity to land on autorotation.

the helicopter has the opportunity to land on autorotation.

this is only in theory, in practice this requires a high altitude and minimum horizontal speed, in a real war this is unlikely.

And speaking directly, a helicopter is also not the most "ideal aircraft", because the higher the flight speed, the greater the percentage of fuel burned is spent on braking.

Do not bullshit.

Familiarize yourself with the mechanics of the main rotor, and, resistance (braking) during the movement of the blade forward in the direction of the aircraft, and only then write such statements ...

[vovochkarzhevsky]

I got acquainted, and not with mechanics, but with aerodynamics, even before your birth.

[uav80]

Avatar came out 20 years after the first flight of Osprey, so Kemer "drawn" his technique from a real device ..

[ProkletyiPirat]

yeah, and the first envelopes (osprey, the first serial, and not flying) were generally 50 years before the avatar

[tralflot1832]

I wonder if more than 50 pieces were produced, how many widows did they make, not only with the pilots, but also with their passengers?

[sifgame]

Not that there are too many, but I would not sit in this pepelats

[uav80]

According to the media count, there are 47 dead, both pilots and passengers, but this is without data on the extreme incident in Glamis, while the information is classified there, and for some incidents that were earlier, there is evidence that there were wounded but what happened to them further the military does not give information.

[tralflot1832]

Can the American wiki be trusted?

[uav80]

Not necessarily a wiki, there are other sources like lostarmour or various aviation forums. On the same lostarmour, information only from 2010 about 13 incidents in which 21 Osprey people died, in Glamis 5 out of 5 are confirmed ..

[tralflot1832]

The American wiki already gives 51. Plus a strange jump without a parachute of the crew commander in Afghanistan.

[iouris]

In addition to flights caused by operational necessity (!)
So if the American Airborne Forces receives an order to fly from Romania to Zaporozhye, then it will fly.

[Crimean partisan 1974]

So if the American Airborne Forces receives an order to fly from Romania to Zaporozhye, then it will fly.

.... this is doubtful .... an easy target

[Ros 56]

Let's clarify the definition, try to fly,

[uav80]

there have been four accidents since 2017

Why the authors of the article have been counting disasters since 2017 if the device has been in operation since 1990 and during this time there have been more than 17 incidents with it ...

[Ros 56]

Someone here praised them very much and reproached us why we do not have them.

[ProkletyiPirat]

here you don’t need to distort, with us, and not only with us, praise convertiplanes, not ospreys. I am also a supporter

An aircraft-like military transport aircraft with vertical takeoff, landing and hovering (VVPZ), designed to transport one piece of equipment and capable of unloading and loading it onto water and wooded surfaces by a non-stop method (i.e. through a cable special lift)

and if you look at the description of Osprey, he doesn’t transport equipment at all.

[aszzz888]

According to a statement by the US Air Force Special Operations Command, not a single tiltrotor will take off again.

Come on, Hollywood people!

[House 25 Sq. 380]

For that kind of money, each unit can hire a personal fedex mail board ...

[Svetlana]

The problem with the clutch inside the gearbox, which connects one of the two Rolls-Royce Liberty AE1107C engines to the propeller rotors of the CV-22 Osprey tiltrotors, can be solved by switching to the tiltrotor propeller drive from electric motors.

[ProkletyiPirat]

there the problem is not with the clutch itself, but in the entire transmission, due to which either the transmission units or the engine itself break, plus all this is fucking as multiplied by a shitty air intake and purification system. There are other schools of analysts and design engineers.
