LIFT, DRAG, AND STATIC STABILITY OF A BLUNT CONICAL MODEL IN HYPERSONIC RAREFIED FLOW

Abstract

This is a report of results and analysis of measurements of forces on spherically capped cones of 10-deg half-angle, with and without conical afterbodies. These data were obtained during the course of an evaluation of a new three-component balance for use in a low-density, hypersonic wind tunnel. Comparisons are made with modified Newtonian and free-molecule theories. Measurements were made in nitrogen gas at a nominal Mach number of 9.8 and unit Reynolds number of 760/in. The suitability of the low-load, three-component balance for measuring aerodynamic forces in low-density flows is demonstrated.
