Aerodynamic Characteristics and Flap Loads for a Blunt Pyramidal Configuration at Mach 5 and 8. Part of an Investigation of Hypersonic Flow Separation and Control Characteristics

摘要

Six-component force and moment data were obtained for Mach 5 and 8 flows over a blunt pyramidal configura tion. The model had a triangular cross section and was composed of two dihedral surfaces and a 70-degree sweepback delta wing lower surface. Three-component force and moment data were obtained on a remotely controlled trailing edge flap at deflections up to 40 degrees. All three surfaces had trailing edge flaps and the model was tested with and without canards and a ventral fin. The model was pitched at angles of attack between =54 degrees and side-slip angles between -4 and +14 degrees. For both Mach numbers, the data were obtained for a nominal free stream Reynolds number, based on model length, of 4.5 million. Selected configurations were tested at other Reynolds numbers between 1.2 and 9.1 million. (Author)
