North American X-10 : ウィキペディア英語版 | North American X-10
The North American X-10 (model RTV-A-5) was an unmanned technology demonstrator, developed by North American Aviation. It was a subscale reusable design that included many of the design features of the SM-64 Navaho missile. The X-10 was similar to the development of Bell's X-9 Shrike project, which was based on features of the GAM-63 RASCAL. ==Development== To facilitate development of the long-range Navaho surface-to-surface cruise missile, North American Aviation (NAA) developed the RTV-A-5 (Research Test Vehicle, Air Force), or X-10 in 1951. This vehicle was to prove out critical flight technology for the design of the cruise vehicle of the Navaho missile design. These included proving the basic aerodynamics out to Mach 2, flight testing the inertial guidance unit and flight control avionics to the same speed, and finally validate the recovery system for the next phase in the Navaho program. Preliminary design of the X-10 was completed in February 1951 and the first vehicle was delivered to Edwards Air Force Base in May 1953. The first flight occurred on 14 October 1953.〔Gibson, James N. ''The Navaho Missile Project: The Story of the Know-How missile of American Rocketry.'' Atglen, Pennsylvania: Schiffer Publishing, 1996. ISBN 0-7643-0048-2.〕 The X-10 was powered by two Westinghouse J40 turbojet engines with afterburners, and equipped with landing gear for conventional take off and landing. The combination of a delta wing with an all-moving canard gave it extremely good aerodynamics in the trans-sonic and supersonic environments. It also made the vehicle unstable requiring active computer flight control in the form of an autopilot. Thus, the X-10 is similar to modern military fighters which are flown by the onboard computer and not directly by the pilot. In this same regard, though the X-10 was receiving directional commands from a radio-command guidance system, these commands were sent through the on-board computer which in turn implemented the commands. Later X-10s included an N-6 inertial navigation system which completely controlled the vehicle through the cruise portion of the flight.〔Miller 2001, pp. 138–139.〕
