In order to examine the effects of the configuration of airframe integration on the scramjet inlet performance, preliminary calculations of the engine performance and wind tunnel tests were carried out for several types of the integrated inlet models. It was desirable to have an inlet inhaling the air compressed by the shock wave from the nose of the airframe, as well as to have the engine being integrated on the airframe paralleled to the airframe axis. In the experiment, the aerodynamic performances of the inlets were compared in terms of the total pressure efficiency and the mass capture ratio measured at the isolator. The experimental parameters were location of integration, type of compression, and strength of forebody compression. In the case that the inlet was attached on the ramp surface, and then turned parallel to the airframe axis, inlet (and the overall engine) showed good performances. This configuration could inhale the precompressed air effectively while reducing the cowl drag.
