ABSTRACT

The problems of drag minimum and of the lift-to-drag ratio maximum of a wing-body system at hypersonic flow are considered. The shape of the middle surface of the trapezoidal wing and the distribution of the wing thicknesses at a given volume are varied. The influence of the viscosity effects on the aerodynamic characteristics of the optimal shapes is considered.
