FORCE TESTS OF A SLOTTED SEMISPAN DELTA WING MODEL AT HYPERSONIC MACH NUMBERS

Abstract

Tests were conducted to determine the effect of slots on the aerodynamic characteristics of a semispan 70-deg swept delta wing. The purpose of the slots was to reduce the model viscous drag by bleeding off the windward surface boundary layer. Data were obtained at nominal Mach numbers of 6 and 10 at free-stream Reynolds numbers, based on wing root chord, of 15,200,000 and 6, 400,000 and angles of attack from -2 to 14-deg. Selected test results are presented and illustrate that the effects of the slots and Reynolds number variation were small.
