How does the V-22 Osprey share engine power between its rotors?

It is possible to drive the two rotors of the V-22 Osprey from a single engine using a segmented driveshaft connecting both engine shafts via gearboxes: The drive shaft is depicted in blue in the ...

How does a tiltrotor yaw while in vertical flight?

The V22 Osprey yaws by tilting one rotor backwards from the vertical and one forward by moving the swashplate up on one side and down on the other causing a cyclic change to the rotor blade angles of ...

How does the V-22 Osprey share engine power between its rotors?

Tilt rotors and virtually every other VTOL aircraft with more than one lift rotor (Chinook, K-Max) or proprotor (AW609) must employ a shaft between these lift units, so when one engine is out the ...

Could the V-22 Osprey be used as a close air support platform?

Can it be? Sure. Let's take a look at what it would be replacing. The A-10 was designed from the ground up to be a platform for moving the GAU-8 into range of the target. It has good low speed ...

Is the CV-22 / MV-22 Osprey classified as a helicopter, plane or both?

They are classified as Tiltrotors, which is its own category for all the obvious reasons. If the President were flying in a Marine Osprey, the callsign would be Marine One. If he were in an Air Force ...

Could the V-22 Osprey be used as a close air support platform?

The V-22 is not without its strong points as a support aircraft. However, CAS is a specialized role for which it will never truly be ideal. That's not to say it wouldn't be feasible to deliver ...

Is the CV-22 / MV-22 Osprey classified as a helicopter, plane or both?

Under the FAA, a CV/MV-22 Osprey is considered to be a powered lift aircraft. Under 14 CFR ยง1.1: Powered-lift means a heavier-than-air aircraft capable of vertical takeoff, vertical landing, and low ...

Why does this V-22's rotors rotate clockwise and anti-clockwise (the right and the left rotor respectively)?

A couple of things. One, I suspect the reason is similar to why the arrangement is also used on the P-38 Lightning airplane from World War II. The counterrotating engines on that airplane originally ...

How is it safe for helicopters and Ospreys to refuel in mid-air?

When fully extended the probe does extend past the rotor of the HH-60G; however, there is a potential for the probe not to extend. And in that case, the probe is well inside the rotor disc. Still, ...

What are these diagonal devices above the leading edge of the V-22 Osprey's wing?

The protrusions you're asking about are vortex generators. As to how they work, there is a separate Stack Exchange article on that: How do vortex generators work? (Please note, the linked question/...

If an Osprey found itself unable to rotate its engines to vertical, what would be the emergency procedure for landing?

A fixed nacelle landing is an emergency procedure practised routinely in a flight simulator, however actually getting this condition is very rare to date. In short, we reduce gross weight if able, ...

How does the V22 Osprey manage such high rotor speeds without shock waves?

The Osprey's engines drive the rotors at 412 RPM in heli mode or 333 RPM in forward-flight mode, according to this article. With a rotor radius of 5.8m, that puts the tip velocity at 250m/s, or about ...

Does the Osprey have a "worse" downwash than a helicopter of equal weight?

higher disk loading... means a more concentrated downwash Correct and this can be demonstrated even using a very simplified approach like the momentum theory by which the airspeed $w$ under a rotor ...

Why can Boeing V-22 Osprey carry more cargo internally than externally?

The difference is because when the cargo is inside the aircraft the weight is spread across the cargo compartment floor, whereas when it is carried externally, the weight is concentrated entirely on ...

Why does this V-22's rotors rotate clockwise and anti-clockwise (the right and the left rotor respectively)?

I can't really comment on Carlo's answer about interference with the empennage, but one result of the wingtip propellers turning against the tip vortex is that it effectively increases the length of ...

How does the V-22 Osprey share engine power between its rotors?

The cross shaft of the V-22 is normally unloaded. It only takes up the load if an engine fails, at which point everything continues as normal albeit with reduced power. Alternatively, if the shaft ...

From which rating would it be easier to transition to an Osprey? Fixed-wing or rotary-wing?

The Osprey is closer to a helicopter and if I was going to chose from a fixed wing pilot or rotary pilot to train on it I'd choose the rotary pilot. The rotary wing physical skill set is so much more ...

What is lifting force of V-22 Osprey? Is any other than the two rotors?

The lift is provided by the rotors only. The rotors are powered by Rolls-Royce T406 engines, which are turboshafts: all useful generated turbine power is converted into shaft power for the rotors. ...
