无人机发射过程仿真与参数敏感性分析

Simulation of Unmanned Air Vehicle Launching Process and Its Sensitivity Analysis

在考虑了发动机螺旋桨转子系统陀螺力矩的情况下 ,建立了无人机发射过程的数学模型 ;以某型无人机为例 ,进行了仿真计算 ,并与实际试飞结果进行了比较。结果表明 ,两者具有良好的一致性。此外 ,对气动参数。

In this paper,the general motion equations of the unmanned air vehicle in consideration of propeller movement are outlined and derived.A numerical simulation of unmanned aircraft launching process is completed and its results are compared with real flight test results and the comparison shows that the consistency between the two results is fairly good.Furthermore,various effects,such as aerodynamic parameter,flight control parameter,rocket fixed parameter,on take off performance for the unmanned air vehicle are analyzed.
