1/72 Bell X-22 Tilting ducts Vtol experiment

Anigrand Craftswork - 1/72 Bell X-22 Tilting ducts Vtol experiment.
During early 1950s, Bell Aircraft began studying conventional propeller and jet design. In 1957, Bell signed contract from Navy for design of ducted propeller assault transport with Vtol capability. This study also caught attention of the Air Force, Marine Corp and Army, and joined for study during 1959. In 1962, Bell and Navy signed contract for the new test-bed, designated X-22. Its design that could fit on carrier elevators and the duct around the four propellers would provide a safety benefit to personnel working in ship's flight deck. The X-22 first flew and was completed successfully on March 1966. Five months later, during its 15th flight, it was involved in a major accident and damaged that caused by a dual hydraulic system failure. The remaining parts were used to complete the second X-22 which took over the flight test program. It first flew in 1967. After completed 228 flights, the program was ended in 1984. Now it displays on Niagara Aerospace Museum at Niagara Falls, Ny
