Abstract:
Conceptual design and experimental wind tunnel testing of unmanned entry research vehicles having high hypersonic lift/drag ration and high volume are desribed. Analytic parametic data are presented for two lifting body classes designated HLD-35 and FDL-5. The FDL-5 is a unique configuration which is aerodynamically stabilized without outboard fins. Experimental aerodynamic and heat transfer data from the Arnold Engineering Development Center Wind Tunnels A, B, C and F are compared with analytic data for the FDL-5. Candidate structure and subsystems are selected for performing unmanned hypersonic research with the vehicle.
