火箭助推无人机起飞段发射动力学建模与分析

为研究某无人机火箭助推发射起飞段的动力学特性，建立其发射动力学模型并进行仿真分析。依据某无人机发射运动的实际问题，建立无人机在导轨上运动阶段的发射动力学数学模型，推导其离轨发射运动方程组。然后利用Matlab软件分别取不同的导轨长度和发射倾角进行仿真计算，得到无人机离轨运动规律和离轨运动参数，并对无人机与箱体的安全让开距离进行分析。结果表明，无人机的离轨运动特性与滑轨长度和发射倾角有关，在一定的滑轨长度和发射倾角下无人机能够安全发射。

Launching Dynamics Modeling and Analysis on Launching Phase for Unmanned Aerial Vehicle with Rocket Booster

For the of certain Unmanned study dynamic characteristics Aerial Vehicle （UAV） with boosting rocket in the launching take - off phase, the launching dynamics model is established to simulate and analyze. Based on the practical prob- lem of a UAV launching movement, the launching dynamics mathematical model of UAV moving on the guide rail stage is founded, and then its launch movement equations are deduced for UAV when leaving the rail. Then different track length and emission angle is used to simulate and calculate by the Matlab software, so that its movement parameters and laws of UAV are obtained, and the safety distance between UAV and the launch container is analyzed. The results show that the takeoff movement characteristics of UAV are related to rail length and emission angle, and UAV can be launched safely in a certain track length and emission angle.
