HEURISTIC MODEL OF NON-STEADY LONGITUDINAL AERODYNAMIC CHARACTERISTICS AT HIGH ANGLES OF ATTACK

摘要

A heuristic correction of longitudinalaerodynamic characteristics CL(α) and Cm(α)at high angle of attack is considered. Twocorrection components are considered: regularand random. Regular component is designed aspiecewise linear dependence of angle of attackfiltered by first order lag block. Randomcomponent is used for buffeting simulation.
