Fastrac or alternatively MC-1 engine was a pump-fed liquid rocket engine developed by NASA for use on small inexpensive, expendable rockets. Fastrac uses RP-1 kerosene and liquid oxygen as propellants in a gas-generator power cycle. Ignition of engine was achieved via starter fluid injected into combustion chamber before kerosene was fed. Propellants are fed via a single shaft, dual impeller turbo-pump. The engine design used an inexpensive, expendable, ablatively cooled carbon fiber composite nozzle, and produced 60,000 lbf (285 kN) of thrust. Engine system development testing of the MC-1 began in 1997 〔http://ntrs.nasa.gov/search.jsp?R=20000064017〕 and continued until the Fastrac program was cancelled 2001, 48 tests were conducted on three engines using three separate test stands. The engine never flew, but with NASA's cooperation much of the MC-1 design and technology was adopted by the private corporation SpaceX for its Merlin 1A engine〔(Barber-Nichols, Inc turbopumps )〕 ==MC-1 later designation== After the cancellation of the FASTRAC program NASA tried to salvage this design for use in other rockets such as Rotary Rocket and X-34 project. The designation of the rocket engine was changed from the Fastrac 60K to MC-1. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Fastrac (rocket engine)」の詳細全文を読む スポンサード リンク
