Analysis of an aircraft departure and spin characteristics using Nash equilibrium theory

The departure characteristics and steady-spin characteristics of a training aircraft are analyzed. The sideslip departure characteristics of the aircraft under the maximum weight and the minimum weight are obtained, respectively. When predicting the steady-spin, the equilibrium point of the spin is found by an analytic-graphic method based on “Nash equilibrium theory”, and the steady-spin parameters of this aircraft are obtained under the conditions of maximum weight and minimum weight, left spin and right spin, neutral controls and prospin controls. The simulation results have good theoretical significance for the optimization and improvement of the aircraft in the preliminary design stage.
