Creation of reliable methods for calculating aerodynamic characteristics of aircrafts with allowance for the fact that their dependence on the parameters of motion is essentially nonlinear and sometimes even controversial is of interest, in the context of both developing nonstationary supersonic aerodynamics and solving a number of practical problems of control for motion of investigated bodies. In this paper, the problem of calculating nonlinear aerodynamic characteristics of a sharp cone is considered. Among numerical models, the most complete one is a model described by the Navier–Stokes equations; it allows one to take into account effects of compressibility, viscosity, and thermal conductivity of the gas with the use of the hypothesis of turbulent viscosity and diffusion. The results of calculations are compared with the data obtained in experiments on the ballistic track of the Ioffe Physico-Technical Institute at Mach numbers $M=1,5$.
Keywords: supersonic flow, turbulent flow, coefficients of drag and lift.
Mots-clés : compressible viscous fluid
