Aerodynamic and thermal characteristics of star-shaped bodies at the angle of attack in a hypersonic rarefied gas flow (Q1063485)

The method is based on the ''localization hypothesis'' developed by the first author in: Izv. Akad. Nauk SSSR, Mekh. Zhidk. Gaza 1973, No.4, 89- 95 (1973). The variation of drag coefficients and heat flux coefficients of star-shaped bodies with different thickness ratios with angle of attack at 70 km and 110 km high in atmosphere are given in four figures, respectively. Some comparisons with results for cone-shaped bodies are also shown in the figures. These calculated results may be served to estimate the drag coefficients and heat conduction for various shapes of bodies and to select the optimum body shape.
