Civilian Boeing V-22 Osprey

[jcf]

I don't understand where this "small payload"
stuff is coming from, the MV-22 can carry up
to 20,000 lbs, far more than the CH-46 the V-22
replaced in the USMC, and only 4,000 lbs less
than what a CH-47F can carry.

The CH-53E comparison is ludicrous as the
V-22 was never designed as a "heavy-lift
helicopter".

Payload vs power. From below tables, you can see that the MV-22B in comparison to the CH-47F has about 25% more power to move only about 45% of the load. But at more than twice the speed.

Power:
MV-22B: Powerplant: 2 × Rolls-Royce T406-AD-400 turboprop/turboshaft engines, 6,150 hp (4,590 kW) each
CH-47F: Powerplant: 2 × Lycoming T55-GA-714A turboshaft engines, 4,733 shp (3,529 kW) each

Weights:
MV-22B:
Empty weight: 31,818 lb (14,432 kg)
Combat weight: 42,712 lb (19,374 kg)
Max payload (incl fuel): 10,894 lb (4,942 kg)

CH-47F:
Empty weight: 24,578 lb (11,148 kg)
Max takeoff weight: 50,000 lb (22,680 kg)
Max payload (incl fuel): 25,472 lb (11,712 kg)

Speed:
MV-22B: Maximum speed: 275 kn (316 mph, 509 km/h)
CH-47F: Maximum speed: 170 kn (200 mph, 310 km/h)

Please note that I'm not questioning the machine as such. It an awesome aircraft, and there's no rival able to insert assault forces quite like the Osprey. It's fast, which can be very, very important in an airborne assault operation, BUT - it is a lot of power and money to move a relatively small weight, compared to a helicopter. You have to have a good reason to get it, and the US and Japan does, apparently. Possibly as both navies have flattops.

Now - I'd like a few to get stuff over to Gotland in an emergency, but then again - a C-130 or a A400M will move more stuff faster, and there are at least four possible landing strips on the island, the airport unaccounted for. However, if you can't take off with a C-130, say from a carrier, then rotary is the only way to go.

C 130 on or off a carrier.................oh yes you can!!    https://theaviationgeekclub.com/the-story-of-how-the-c-130-hercules-became-the-biggest-aircraft-to-land-on-an-aircraft-carrier/  Not the usual procedure, but it can be done.

IIRC the rotors on the V-22 were made smaller then what would have been most efficient to make it easier to store onboard ships. So that's one of those trade offs you have to make when designing aircraft, especially military aircraft. Every aircraft is full of trade offs determined by the mission. Everything I've seen says the V-22 is really good at its mission. It flys so much faster than it's escort helicopters that they have to launch well beforehand to arrive at the LZ at the same time.

Fine Pellson, believe whatever you want, and I notice that you skipped including the Osprey's
STO numbers, most likely because they don't fit your predetermined narrative.

How is yaw adjusted when an Osprey is hovering?
A helicopter has a tail rotor to do this.

You'd be better off asking Evan (elmayerle) over on BtS but Google came up with this:

Answer. 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 attack. This is accomplished using the pedals in just the same way as a helicopter.

I don't know where the answer came from, though, nor how accurate it is, but it makes sense.

It doesn't have to move very much either, at the Yuma show this V-22 was doing pirouettes in front of the crowd line, you can just make out the direction the nacelles are pointing.

Thanks folks.
