Technical Memorandum of National Aerospace Laboratory
A Hypersonic Flight Experiment (HYFLEX), which is one of the flight experiment series prior to the development of HOPE-X (H-2 Orbiting Plane-X), was conducted on February 12, 1996 as a joint project between NAL and NASDA (National Space Development Agency of Japan). As a part of the conceptual study of HYFLEX by NAL, six-component force tests of two different vehicle types were performed at Mach 10.8 using NAL middle scale shock tunnel. One model used delta wings (HRV02) and the other had the so-called lifting body configuration (HRV03), both of which were assumed to be launched by a two-stage version of the J-1 launcher of NASDA. The results of the present test were used in the trade-off study of the vehicle's configuration. The results were also compared with numerical prediction using Newtonian flow assumption and Prandtl-Meyer expansion in order to estimate the accuracy of such a method; this method was employed in the determination of the base-line configuration for preliminary design of HYFLEX.
