| 摘 要： | 针对动力伞的动力学研究,建立了全量模型研究无人动力伞飞行中动态特性问题。在惯性系下从牛顿力学基本原理出发,用矢量方法推导无人动力伞的动力学方程;经过坐标转换,得到动力学方程在体轴系下的形式,并补充运动学方程,使方程组满足封闭性要求,从而建立完整的矢量动力学模型。通过两个仿真算例,分析了动力伞实施推力和航向舵下偏控制的飞行特性,验证了模型的合理性。

| Abstract: | Along with the development of the unmanned powered parachute,a full-state model is required to research the dynamicresponse of the unmanned powered parachute.Then based on the principal the ories of Newton mechanics,a set of dynamic equations are derived to describe the motions of unmanned powered parachute in terms of vector.After translated to the body frame,a full-state vector dynamic model is built.The dynamic response of unmanned powered parachute is analyzed through two simulations.This model proves t... |
