Hypersonic Prediction Comparisons with Experimental Data for a Cone-Cylinder at Mach 6.86.

Abstract

Comparisons of computed flowfield predictions to experimental data for a cone-cylinder configurations at Mach 6.86 and angles of attack of 0, 6.7, 14, and 20 degrees are presented. The two inviscid computer codes used were EAGLE and ZEUS, which represent a time-iterative and a space-marching approach, respectively. Specific comparisons were made between the predicted and the experimental pressure distributions along the body at various circumferential locations, as well as aerodynamic characteristics of normal force coefficient and the location of the center of pressure. The inviscid calculations compare well with experimental data where viscous effects are minimal. Keywords: Aerodynamics; Hypersonic; Cone-cylinder. (jhd)
