PRESSURE AND HEAT TRANSFER MEASUREMENTS FOR MACH 8 FLOWS OVER A BLUNT PRYAMIDAL CONFIGURATION WITH AERODYNAMIC CONTROLS PARTⅠ:PRESSURE DATA FOR DELTA WING SURFACE

摘要

Pressure and heat transfer data were obtained for Mach 8 flows over a blunt pyramidal configuration composed of a 70 degree sweepback delta wing surface and two dihedral surfaces. Trailing edge flap deflections were varied up to 40 degrees on all surfaces, and the model was tested with and without canards and. ventral fins. The model was pitched at angles of attack between ±54 degrees and was tested at sideslip angles of 0 and 12 degrees for free stream Reynolds numbers, based on model length of 1.5 and 4.5 million.
