Bell X-16

From Wikipedia, the free encyclopedia

The Bell X-16 was an aircraft designed as a high altitude reconnaissance jet aircraft in the United States in the 1950s. A mockup of the X-16 was built, but the project was cancelled in favor of Martin RB-57 before any X-16 aircraft were completed. The designation of X-16 was a cover to try to hide the true nature of the craft from the Soviets during the Cold War.

[edit] Development

During the second half of 1953, Fairchild, Bell, and Martin Aircraft conducted high-altitude reconnaissance aircraft design studies for the U.S. Air Force. All three designs used Pratt & Whitney J57-P19 engines. The Bell (X-16) and Martin (B-57D) designs were chosen for further development. The Bell design was designated the X-16. The X-16 project was cancelled by the Air Force in favor of Martin RB-57 in 1956. A full-scale X-16 mockup was completed and one aircraft was partially completed. It was designed as a high-altitude long-range reconnaissance aircraft. A total of 28 aircraft were ordered, but none were completed. The first X-16 was about 80-percent complete when the program was cancelled in 1956.

The X-16 design was breaking new ground with its design. Its wing was extremely long with a high-aspect ratio. It was significantly lighter and more flexible than any in existence at that time. The entire aircraft was made as light as possible to fulfill its mission of a 3,000-mile unrefueled range at a 70,000 foot altitude.

Although no X-16 was ever completed, it made contributions to aircraft design with its lightweight design. It was also a driving force behind the development of the high-altitude J57 jet engine that would later power the U-2 and other aircraft.
