Abstract

The mathematical model of aerodynamic characteristics with inclusion of the non-stationary components corresponding to structure of a flow and), in nonlinear and linear representation is considered. It is explained cosinusoidal dependence rotary and also linear non-stationary derivative of a corner of attack. New approximations of functions are offered: (with the parameter dependent on centering of the plane) and (with, having two rough local minima). Communication expressions with derivatives, calculated of complexes, experimentally measured in wind tunnels is determined. The technique of a choice of parameters of dynamic making aerodynamic characteristics for modeling is resulted.
