PRESSURE AND HEAT-TRANSFER MEASUREMENTS ON A SLOTTED LEADING EDGE IN HYPERSONIC FLOW

Abstract

Pressure and heat-transfer tests were conducted using a highly swept cylindrical leading-edge model. The effects of slots and slot geometry were investigated. Slots were varied in width and depth from 0 to 0.50 in., and the leading-edge sweep angle was varied from 45 to 90 deg. The tests were conducted at nominal Mach numbers of 6, 8, and 10. Pressure data were obtained at a free- stream Reynolds number of 1.0 million/ft, and heat-transfer data were obtained at 1.0 and 2.0 million/ft. Selected results are presented to show the effect of the slots upon the leading-edge pressure and heat-transfer distributions.
