Creation of reliable methods for calculating the aircraft aerodynamic characteristics with allowance for their essentially non-linear and sometimes ambiguous dependence on the motion parameters is of great interest, both in the aspect of developing non-stationary supersonic aerodynamics and for solving some practical problems of control for the motion of bodies under study. The investigations are intended to solve the problem of dynamic interaction between a real gas and a body moving within it in conditions of a significant change in kinematic parameters. In this paper, the problem of calculating nonlinear aerodynamic characteristics of a sharp cone is considered. The most complete numerical model is that described by Navier–Stokes equations, which allows taking into account the effects of gas compressibility, viscosity, and thermal conductivity with application of several models of turbulence and diffusion. The obtained results of calculations are compared with results of ballistic experiments.
Keywords: supersonic flow, turbulent flow, drag and lift coefficients.
