Abstract

On the basis of the specified model of aerodynamic factors of the longitudinal movement, taking into account non-stationary effects отрывного flows at the big corners of attack, the mathematical model of spatial movement of the maneuverable plane with reduction of its(her) system of the nonlinear differential equations an initial kind is constructed. The initial data for introduction in the program of the decision of the specified system on the digital computer are prepared. The initial data on aerodynamic factors are taken from known (covering ranges 0...90o for corners -40o...40o for corners ). Also are approximately predicted for corners -720o...720o under the periodic law. The constructed model is illustrated with decisions at various positions of controls by plane.
