The first XV-15 prototype aircraft, N702NA, was transferred back to Bell for company development and demonstration use. On 20 August 1992, the aircraft crashed while being flown by a guest test pilot. He was lifting off for a final hover when a bolt slipped out of the collective control system on one pylon, causing that rotor to go to full pitch.
Original Patent filed May 28,1929 Transcendental Model 1-G hovering Bell X-22 A Bell XV-15 prepares to land. The first work in the direction of a tilt-rotor (French "Convertible") seems to have originated ca. 1902 by the French-Swiss brothers Henri and Armand Dufaux, for which they got a patent in February 1904, and made their work public in April 1905.
Bell created the V-247 to meet emerging U.S. military needs for a runway-independent Group 4 or 5 UAV to provide persistent support to ground forces while requiring less space to store and transport; Group 4 UAVs weigh more than 1,320 lb (600 kg) and fly below 18,000 ft (5,500 m), while Group 5 UAVs weigh the same but fly above 18,000 ft, such as the MQ-9 Reaper, RQ-4 Global Hawk, and MQ-4C ...
The squadron is a Marine Corps test and development unit. Its mission is to conduct operational testing and evaluation of Marine Corps fixed, tiltrotor, and rotary-wing aircraft. The unit was re-designated to VMX-1 (from VMX-22) on 13 May 2016. [88]
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.
The Bell X-22 is an American V/STOL X-plane with four tilting ducted fans.Takeoff was to selectively occur either with the propellers tilted vertically upwards, or on a short runway with the nacelles tilted forward at approximately 45°.
The distributors allegedly targeted pill-mill pharmacies in the Houston area, according to the complaint, because Houston is “a nationally recognized ‘hot zone’ for diversion of ...
In 2016, it was noted that the active blade control system developed for Project Zero, which removes the need for a swash plate and a separate vibration-damping system, was to undergo flight testing on an AgustaWestland AW139; separately, the flight control laws used by Project Zero shall be used for a future tiltrotor project by AgustaWestland.
