Experimental Studies on Aerodynamic Characteristics of SSTO Vehicle at Low Subsonic Speeds

As for a fully reusable space transportation system of a single stage to orbit(SSTO) of horizontal take-off and landing type, experimental studies on low-speed aerodynamic characteristics have been done. The wind tunnel tests were conducted using NAL's gust wind tunnel. Six-component force and moment data were obtained over an angle of attack range from -14° to 44°. In this paper, the aerodynamic test results are presented for the low-speed aerodynamics of a generic SSTO configuration.
