ABSTRACT
This paper presents results of numeric modeling of three-dimensional flow around the configuration of the piloted orbital spaceship “the winged aerospace vehicle proposed by the central Hydrodynamic Institute.The flight vehicle with nondeflected control devices was examined.The effect of the deflection of the balancing flap on the flow field and the aerodynamic performance of the vehicle is studied here.The efficiency of the flap with its deflection is obtained.Computations were perfomed using the applied program package ARGOLA-2 for thermally nonconductive gas within the range of incident flow mach no. from 1.1 to 16.5 and the angle of attack from 0 to 45degrees.The effect of the real thermophysical properties of air on the aerodynamic performance of the winged ASV at hypersonic speed and the efficiency of the flap is estimated.
