SEPARATED FLOW STUDIES AT HYPERSONIC SPEEDS. PART I. SEPARATED FLOWS OVER AXISYMMETRIC SPIKED BODIES,
CORNELL AERONAUTICAL LAB INC BUFFALO N Y
Pagination or Media Count:
One objective of the report was to obtain detailed information on the heat transfer generated in the reattachment region of a conical shear layer, and determine the influence of reattachment angle, free stream Mach number and downstream expansion on this phenomena. A second objective was to make a systematic study of the parameters which influence the protection of aerodynamic surfaces by means of spiked induced separated flows. The parameters varied were spike length, body shape and free stream Mach number. Measurements of the distribution of heat transfer together with schlieren photographs of the flow over the spiked cones at Mach numbers of 10 and 15 has provided information on the variation of reattachment heat transfer and total heat transfer with body shape and free stream Mach number.
