Abstract

For power elliptical body, the drag force in the high-speed rarefied gas flow is calculated based on several local models. The solution of the variational problem determines the degree of minimum resistance in the generatrix of the body, depending on coefficient of the ellipticity and different elongation in a wide range of Reynolds numbers.

Keywords

elliptical bodies, hypergeometric function, the drag coefficient, coefficient of the ellipticity
