The Bell V-280 Valor is a tiltrotor aircraft being developed by Bell Helicopter for the United States Army's Future Vertical Lift (FVL) program. [2] The aircraft was officially unveiled at the 2013 Army Aviation Association of America's (AAAA) Annual Professional Forum and Exposition in Fort Worth, Texas.
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.
This is a list of fixed-wing aircraft capable of vertical take-off and landing arranged under manufacturer. The list excludes helicopters, including compound helicopters and gyrocopters, because they are assumed to have this capability. For more detail on subtypes of VTOL, see List of tiltrotor aircraft
The drone's full appearance has led to comparisons on Chinese social media to the designs of the Osprey and Bell's V280 Valor, a newer VTOL aircraft that completed its first flight in December 2017.
The Model 1-G flew until a crash in Chesapeake Bay on 20 July 1955, destroying the prototype aircraft but not seriously injuring the pilot. The Transcendental 1-G was the first tiltrotor aircraft to have flown, and it accomplished most of a helicopter-to-aircraft transition in flight to within ten degrees of true horizontal aircraft flight.
The Leonardo AW609, formerly the AgustaWestland AW609, and originally the Bell-Agusta BA609, is a twin-engined tiltrotor VTOL aircraft with an overall configuration similar to that of the Bell Boeing V-22 Osprey. It is capable of landing vertically like a helicopter while having a range and speed in excess of conventional rotorcraft.
The Transcendental 1-G is the first tiltrotor aircraft to have flown and accomplished most of a helicopter to aircraft transition in flight (to within 10 degrees of true horizontal aircraft flight). Built in 1953, the experimental Bell XV-3 flew until 1966, proving the fundamental soundness of the tiltrotor concept and gathering data about ...
Following the completion of the joint service testing, the aircraft was returned to the Ames facility, where on 12 August 1959, Fred Drinkwater became the first NASA test pilot to complete the full conversion of a tiltrotor to airplane mode. On 8 August 1961, Army Major E. E. Kluever became the first Army pilot to fly a tiltrotor aircraft.
