Radioplane Q-1 : ウィキペディア英語版 | Radioplane Q-1
The Radioplane Q-1 was an American target drone, developed in the early 1950s for the United States Air Force by the Radioplane Company. Originally powered by a pulsejet engine, then later developed as an improved turbojet-powered aircraft, the Q-1 failed to win the favor of the USAF. However, the aircraft provided the basis of the GAM-67 Crossbow anti-radar missile. ==Design and development== Shortly after its formation in 1948, the United States Air Force issued a specification calling for a new type of high-speed target drone. Required to be jet-powered to provide the most reallistic training, the contract for the development of the drone was given to the Radioplane Company, later a division of Northrop.〔 Powered by a single Giannini PJ39 pulsejet engine, the drone, given the designation RP-26 by the company and XQ-1 by the USAF, was a high-wing, rocket sled launched aircraft. Originally fitted with a large single vertical stabiliser, the design was modified to a twin tail configuration to provide additional clearance of its carrier aircraft.〔 Recovery, following the conclusion of the drone's flight, was by parachute.〔
