Ляпунов Stability Analysis Based on Nonlinear-Aerodynamic and Nonlinear Equations of Motion of an Aircraft

飞机的稳定性是飞行动力学的重要组成部分,基于飞机空气动力和动力学方程的非线性,将李雅普诺夫稳定性分析方法应用于飞机在定常大迎角飞行状态的稳定性分析,该方法克服了小迎角的局限性,在某型号设计中得到了具体的应用。

Stability of the motion of aircraft is an important part of flight dynamics. In this paper, ляпунов stability analysis based on nonlinear-aerodynamic and nonlinear equations of motion of aircraft is applied to the steady flight state of high-angle-of-attackThis method plays an important role in overcoming the limitation of small-angle-of-attack and finds application in an aircraft design.
