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°.

One of the most unique attempts at vertical flight was embodied in the Bell X-22 that was sponsored by the US Navy during the 1960s. As part of the Tri-Service Program, the US Army, US Air Force, and US Navy each agreed to develop its own vertical/short takeoff and landing (V/STOL) concept under the joint supervision of all three services.

2020年5月14日 · During takeoff, the propellers would tilt upwards or at 45 degrees, demonstrating a new type of aircraft movement that could handle short runways. This revolutionary vehicle – the best of its time - was known as the Bell X-22. The Bell X-22 model continued successful flights into the 1980s, even though the original program was canceled.

The X-22A was the Navy contracted and managed portion of the Tri-Service Assault Transport Program. The Bell X-22A was 39 ft long, featured side-by-side pilot seats, and had a gross weight of 17,000, including six passengers or a 1,200 lb payload.

X-22A Tri~Service V/STOL Research Aircraft. The official contract was authorized on 30 November 1962, The X-22A aircraft is a dual tandem ducted propeller research air- plane (Figure 1), with a prime mission of exploring the mechanical and aerodynamic problem of an aircraft designed and constructed for both

These two experimental aircraft, which were to become the last aircraft built at Niagara Falls, were designated X-22A. During the design phase, Bell researches focused on three aspects: a wide range of centre of gravity movement during hover and transition, sufficient control forces for precise control in hover and transition, and a low empty ...

2023年4月20日 · Bell Aerospace secures the contract to develop the X-22, and on March 17, 1966, the first prototype soars into the sky. The X-22 stands out from other VTOL aircraft of the era with its unique design. Its most striking feature: four ducted fans mounted at the tips of a large, rectangular wing.

Good work by all the fine Bell employees who designed, built, and flew this amazing aircraft! I worked for Bell AeroSpace during the late 60's/early 70's and worked in Quality Control in the R & D Lab.
