V-22 OSPRAY Formidable Aircraft

VIDEO -Tiltrotor in action.
Bell Helicopter V-22 Ospray VTOL aircraft. The V-22 is a fixed wing, tilt rotor, aircraft which takes off, lands, and hovers like a helicopter and rotates its' propulsion system 90 degrees to achieve horizontal flight like a fixed wing aircraft.

Tilt rotor prior art aircraft have five distinctive disadvantages. One is that the aircraft cannot land or take off horizontally like a conventional airplane if for some reason there was a failure of its' apparatus that rotates its' propulsion system while in the vertical flight mode. Another is due to their rotor diameters being so large that the rotors would strike the ground in a horizontal landing or take off scenario. Such a large rotor diameter is necessary however, in order for these aircraft to take off and land vertically.

The second disadvantage is that tilt rotor aircraft must overcome negative angular moments created by their spinning rotors when tilting their rotors 90 degrees during VTOL transitions. These forces act against the aircraft's fuselage creating a difficult control and stability phase for the pilot as the aircraft is transitioning in VTOL flight.

A third disadvantage of a tilt rotor aircraft is that they cannot fly at all if one engine should fail. The fourth disadvantage is one that is shared with helicopters in that tilt rotor aircraft, that do not employ jets or ducted fans, take a sizeable area to land in because of rotor diameter. A fifth disadvantage of tilt rotor aircraft, not employing jets or ducted fans, is also shared by helicopters which is exposed rotor blades that can strike nearby objects or people while landing and taking off.

Similar aircraft to the aforementioned are the U.S. ARMYS'/NASA Doak 16, the French NORD 500 and the Bell X-22; all are classed as tilt rotor aircraft in that the aircraft's propulsion systems are similarly rotated 90 degrees to achieve VTOL transitions. However, the X-22, the French NORD 500 and the Doak 16 employ ducted fans instead of rotors. This configuration allows the respective aircraft to land, take off, and hover like a helicopter and yet land and take off horizontally like a conventional fixed wing aircraft; they require less space in which to land and do not have exposed rotors.

The aforementioned tilt rotor ducted fan aircraft have two distinctive disadvantages. One is they likewise have negative angular moments acting against their fuselages to overcome when their respective propulsion systems are rotated 90 degrees during VTOL transitions. The second disadvantage is that they use ducted fans which, when employed in horizontal flight, limits their forward speed. The forward speed limitation of ducted fans is due to the fact that they build up a boundary layer of air immediately in front of the ducts at higher forward air speeds. This limits their forward airspeed to that of helicopters thus limiting their application on VTOL fixed wing aircraft.

Glad you know how to spell Osprey

[salakast]

@TheLigitGamerrrrr GTFO ITS ALL ABOUT SUPER MARIO *sarcasm*

[Sonofsweetness]

Halo reach got their design for the falcon from the osprey, didn't they? Oh well back to MW3

[TheLigitGamerrrrr]

@MrEpicChancho GTFO its all about BF3!!

Ospray=Marine killer!!!  Gearbox failure and it drops like a rock.

@aeropolicialmexico the V-22 Osprey isnt a hellicopter, its a tilt wing/rotor VTOL/STOVL aircraft.

also in regards to the end of the video, the ospray isnt likely to be used in actual operations any time soon due to problems and contreversy.

just thought you should know! :)

Looks a bit cumbersome to me.

@MrEpicChancho the virginity is strong on your comment.
