PRESSURE DISTRIBUTION ON BLUNTED FLAT PLATES WITH SURFACE INCLINATION

Abstract

Surface pressures and heat transfer were measured on 2 flat plates blunted by a semi-cylindrical leading edge at a nominal Mach number of 8. The nose radii of the 2 models were 0.10 and 0.50 inches. Both models had a chord length of 11.0 inches. The effects of angle of attack, Reynolds number, and nose radii on the surface pressure distribution were considered. Tests were conducted over a range of 0 to 30 degrees surface inclination. The free stream Reynolds number varied from 0.43 to 2.00 x 10 to the 6th power per foot. Several existing theories are presented and comparisons are made with experimental data. Shadowgraphs of the flow about each model are included for several angles of attack.
