一、概述 飞机在急滚机动中的稳定性问题,是最重要的大扰动运动问题之一(另一种是尾旋问题),这一观点在飞行品质规范中也得到反映。对于此类问题,除利用计算机求解5阶非线性动力学微分方程外,另一方法是分析方程的稳态解。由于对方程采用了种种简化,后一种方法常常得不到某些精确的量的概念,但对于寻求急滚交感运动的稳定 First, an overview of the stability of the aircraft in the maneuvering of the maneuver is one of the most important problems of large perturbation (the other is the problem of maneuver), which is also reflected in the flight quality specifications. For such problems, in addition to using computers to solve the fifth-order nonlinear dynamic differential equations, another method is to analyze the steady-state solution of the equations. Due to various simplifications applied to the equation, the latter approach often fails to give some precise quantitative notions, but for the sake of seeking stability of the ebb and flow sympathetic movement
