PECULIARITIES OF DRAG OF THE REVOLUTION POWER-LAW BODIES

ABSTRACT

The results of numerical investigation of the drag of the revolution power-law bodies at supersonic free stream velocities are presented in this paper. Qualitative peculiarities of supersonic overflow, associated with the drag of optimal axisymmetric aerodynamic configurations, are considered. The peculiarities of the rise of the minimum of the drag coefficient function of the generatrix exponent are revealed in the class of power-law revolution bodies at supersonic overflow. It is shown that the wave drag coefficient along the length of an optimal power-law revolution body increases according to the function, which is close to be linear.
