无人机伞回收动力学分析

在建立无人机六自由度飞行力学模型和降落伞回收动力学模型的基础上,对无人机的整个回收过程进行仿真分析,并与飞行试验进行了比较。结果表明:本文所采用的方法较为准确地预测了整个减速伞工作阶段中的相关动力学特性。计算结果还包括了无人机与回收系统的相对运动过程,有效地预测了回收过程的危险情况,为无人机控制律和回收系统设计提供了重要参考。

Dynamics Analysis on Parachute Recovery of Unmanned Aerial Vehicle

Based on six degrees of freedom(DOF) flight dynamics model of UAV and parachute recovery dynamic model,a quantitative prediction of the whole motion process is given after simulation.For validating the method,a comparison is made between the computational results and available flight test data,and achieves favorable agreement.The simulation results include relative movement of UAV and recovery system and predict dangerous situations at recovery stage,which are an important reference for the design of UAV control law and recovery system.
