Evaluation of Aerodynamic Performance of a Hypersonic Experimental Aircraft

Hypersonic Turbojet Experimental vehicle is a vehicle proposed for the flight test at Mach 5. The capacity of the installing equipment has increased at recent design review. Therefore, it is necessary to increase the body volume. In this study, aerodynamic performance of this vehicle was examined to evaluate effect of body volume on aerodynamic performance. And effect of body shape on aerodynamic performance was evaluated. As the results, the body height is found not to affect the longitudinal static stability, but the directional static stability. And the effect of flow around airframe on aerodynamic performance is small.
