The Bell Boeing V-22 Osprey is an American multi-use, tiltrotor military transport and cargo aircraft with both vertical takeoff and landing and short takeoff and landing capabilities. It is designed to combine the functionality of a conventional helicopter with the long-range, high-speed cruise performance of a turboprop aircraft.
The Lockheed Martin FB-22 was a proposed supersonic stealth bomber aircraft for the United States Air Force, derived from the F-22 Raptor air superiority fighter. Lockheed Martin proposed its design in the early 2000s with support from certain Air Force leaders as an interim "regional bomber" to complement the aging U.S. strategic bomber fleet, whose replacement was planned to enter service ...
The Vertical Take-Off and Landing Experimental Aircraft (VTOL X-Plane) program was an American research project sponsored by the Defense Advanced Research Projects Agency (DARPA). The goal of the program was to demonstrate a VTOL aircraft design that can take off vertically and efficiently hover, while flying faster than conventional rotorcraft ...

Bell-Boeing V-22 Osprey, the only crewed tiltrotor in production to date. A tiltrotor is a type of vertical takeoff and landing (VTOL) aircraft that convert from vertical to horizontal flight by rotating propellers or ducted fans from horizontal positions like conventional aircraft propellers to vertical like a helicopter's rotors.
A closeup of one of the V-22 Osprey's dual proprotors. A proprotor is a spinning airfoil that function as both an airplane-style propeller and a helicopter-style rotor . Several proprotor-equipped convertiplanes , such as the Bell Boeing V-22 Osprey tiltrotor , are capable of switching back and forth between flying akin to both helicopters and ...
Bell Boeing V-22 Osprey The Bell Boeing Quad TiltRotor (QTR) is a proposed four-rotor derivative of the Bell Boeing V-22 Osprey developed jointly by Bell Helicopter and Boeing . The concept is a contender in the U.S. Army's Joint Heavy Lift program (a part of Future Vertical Lift program).
