In reply to jsquared:
Yea, he said it was too much multitasking. Then again, he flew Huey's for a long time before being behind a command desk.
FWIW, the osprey was here for a special demonstration for some Rolls Royce employees to see what they had been building engines for. I may or may not have had some turbine blade parts for one come across my desk over the last few years.

Came here to say this. I remember hearing one take off for the first time and thinking "What the hell is that?"
The V22 makes a very unique sound. I live near and work at the Sikorsky factory and hear the various variants of the Blackhawks and other birds all the time, but when V22 made a low pass over my house it had me looking up going "WTF is THAT!"

That might explain it, the pilot has to know fluid dynamics for both fixed and rotary flight, on top of the weirdness they encounter during the nacelle rotation... which could cause some added stress while operating
Transformers deal with that all the time. What's the problem?
Saw one these flying along the beach a year ago and this year during a family vacation. It was pretty wild. At first you're like "Oh look. A twin engine turbo prop." and then you realize "No wait...that's an Osprey..."
Not being smart here, legitimate question: Do they always take that long to transition from forward flight to landing? I'm thinking in anything approaching a "hot" landing zone, they would be dead meat. Or are they intended more for rapid resupply in "uncontested" areas?
Still awesome either way, just wondering.
In the "Tom Clancy" book I'm reading, they specifically mention this as a drawback to the Osprey. In the book it's a reason that Ospreys don't go into the hot zone without Blackhawks. Obviously this may not be true at all.

I suspect gyroscopic (those rotors have a LOT of energy in them) forces and aerodynamic forces (despite acting like a helicopter, I am pretty sure the blades are basically very large props, no cyclic etc.) would make for some bad news if you tried to transition quickly. Trying to run a turbine at full power with the airflow hitting the inlet at an extreme angle may not be too easy either.
Read "Dream Machine" by Richard Whittle. Tells you everything you'd like to know about the development of the V-22. That machine was almost dead 3-4-5 times. We're lucky to even see one.

They fly over us every 3-4 weeks when the president needs to do some fundraising.
Seen it up close at Oshkosh a few times.

No, they can take off from short rolls as well to quicken that transition.

Also, considering the angle this one took off from in Indianapolis, they had to gain the altitude to clear the buildings.
Yes.... to clear my building, specifically.

The last few times he's come there have been a few of them in the area shortly before his three helicopters.
