The air-intake/airframe integration is one of the important problems in the supersonic airbreathing engines such as RAMjet and SCRAMjet. Those kinds of air-intake compress incoming air so highly like as conventional compressors that the induced aerod

In the present study, the influence of the engine unit (air-intake, nacelle and nozzle) to the aerodynamic characteristics of the airframe was experimentally investigated at a free stream Mach number of 2.75. A series of wind tunnel tests was perform

Hypersonic air-breathing engines will make the Earth-to-orbit vehicle completely different from the present one powered by rocket engines. The space plane propelled by a certain hypersonic air-breathing propulsion system is expected to appear in the
