Experimental Testing of an Airframe Integrated 3-D Scramjet at True Mach 10 Flight Conditions

摘要: I. Introduction or the past half century the often quoted civil usage for scramjet engine technology is as a part of an airbreathing access-to-space system. Though no such system has flown, it is generally accepted that performance gains with respect to rocket-based systems could be obtained in the areas of reuseablity, safety margins, and the ability to maneuver downrange. 1-3 All these aspects are generally attributable to aircraft operations, rather than rockets. Increased payload-to-orbit mass fractions and lower launch costs may also be possible. 4 One of the keys to achieving these goals is the development of scramjet powered vehicles that produce sufficient thrust to enable acceleration to high Mach numbers. 4, 5 The highly integrated nature of hypersonic airbreathing vehicles implies that
