    They had one of those at farnborough this year-bloody noisy:)

    Yep and is there any point to them?

    Maybe someone could invent something like a helicoptor with a jet engine…

    Bring back AirWolf.

    You can see the point of them. A fast, heavy lifter. Ideal for inserting SF teams behind the lines. Able to be kitted out with defensive weapons. VTOL, STOL while carrying these heavy loads.

    Pity that the complicated gearing necessary makes them less than reliable.

    Bring on anti gravity.

    I wouldn’t want to be anywhere near the first one which suffers a failure of the tilting mechanism when in conventional flight. In that mode the propeller tips extend well below the undercarriage. If the crew were unable to tilt the rotors upwards (at least partially), I can’t see any outcome but hideous damage, and bits flying everywhere in the subsequent attempts to land it…

    We’ve just been discussing this. My mate is of the opinion that the rotor problem can be overcome and is no more hair-raising than the Harrier. Hmmmm – I’m not so sure.

    I suggest you look at some pictures or video of it in conventional flight. Try this:http://military.discovery.com/tv/osprey/about/images/osprey.jpg
    It would need humongously long Lockeed Constellation style undercarriage legs to keep those blade tips clear of the ground. As it stands the bits would probably end up going through the fuselage and killing anyone unfortunate enough to be inside.

    I note from the Wiki page that is FBW, and this takes care of the different control inputs and functions depending on what mode it is operating in. So even if there was some basic hand-cranked mechanism to wind the engine/rotor assemblies part way up from the horizontal, the computers would need to know what was happening.

    I also see that it has no auto-rotation capabilities, and a double engine failure below 1600ft is not considered survivable. This is contradicted by one pilot who says they can convert it into a plane and glide it down. That might be feasible if it was travelling fairly fast and could transition to conventional flight before the rotors stopped, but it would still have to make a “run on” landing with the rotors partly tilted.

    Sorry, but I am deeply suspicious of this machine…

    Yes, I am too.
