American Helicopter XH-26 Jet Jeep

The American Helicopter XH-26 Jet Jeep (known as the XA-8 by its manufacturer) was an experimental tip jet helicopter developed in 1951 by the American Helicopter Company to meet a United States Army and Air Force (USAF) request for a collapsible and air-droppable observation helicopter.

Design and development

The design of the original Model XA-8 single-seat lightweight helicopter began in 1951 under the sponsorship of the U.S. Army Transportation Corps and the USAF. The Army's specification in 1950 had called for a lightweight, one-man unarmed helicopter that had to be collapsible, capable of aerial delivery to troops in rugged terrain, and assembled quickly with simple tools. The helicopter was to be used for both light observation and as an air-droppable rescue vehicle for downed aircrews. After a review of all proposals American Helicopter was awarded the development contract in June 1951, based on its XA-8 design proposal. The first of five prototype XH-26s flew in January 1952.
