Summary
More and more, the designer of a new reentry vehicle relies on laboratory simulations to evaluate the designs. Numerical simulations of the configuration’s trajectory incorporate data bases for the aerodynamic characteristics of the configuration. These aerodynamic data bases are developed using computations made with state-of-the-art design codes, which are verified by comparisons with wind-tunnel test data. Comprehensive surface pressure and force and moment measurements were obtained on hypersonic configurations at Mach 4.28 for validation of computational tools. The experiments were carried out in the United States Air Force Academy’s Tri-Sonic Wind Tunnel for sharp and blunted bi-conics (which are representative of some reentry vehicle configurations). Data were obtained over an angle-of-attack range of ±10°. These data are compared to results of computed flow models of various sophistication levels.
