飞机横侧动稳定性及反应的奇异摄动理论

SINGULAR PERTURBATION THEORY OF LATERAL DYNAMIC STABILITY AND RESPONSE OF AIRCRAFT

应用奇异摄动法分析横侧小扰动运动的动稳定性问题,将四阶问题分解为小根、大根和复根模态,它对应于经典理论中的螺旋、滚转和荷兰滚模态,并给出了动态反应过程的解。

The singular perturbation theory is applied to solution of lateral dynamic problem. The fourth-order system is resolved into the modes of small, big, arid the complex roots which correspond to the slow spiral motion., the pure rolling motion, and the yawing oscillation respectively.
