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

摘要

A heuristic correction of longitudinal aerodynamic characteristics CL(α) and Cm(α) at high angle of attack is considered. Two correction components are considered: regular and random. Regular component is designed as piecewise linear dependence of angle of attack filtered by first order lag block. Random component is used for buffeting simulation.
