摘要
应用摄动法将飞机四阶线化方程降为二阶方程,导出确定飞机纵向长、短周期模态和横航向滚转、螺旋、荷兰滚模态近似解析解。
The foruth-order linearizing equation of aircraft is reduced to second-order one by perturbation methods. Approximate analytical formulate are derived for determining the longitudinal and the lateral-directional modes characteristics of aircraft.
