摘要

无人机安全发射是正常飞行的前提，其发射参数的优劣直接影响发射安全。针对常规方法进行发射参数设计时，联立求解复杂的问题，提出依据能量法对系统发射参数进行简化计算的方法。在系统建模的基础上，完成了参数分析、模型简化、参数计算，最后对计算结果进行系统仿真验证。仿真结果表明：该方法物理意义明确、简单可行，可用于该无人机助推起飞时的参数计算，为确定发射系统总体方案提供设计依据。%　　The safety launch of unmanned aerial vehicle (UAV) is the premise of its flight. The launch parameters greatly affect the safety of launch. To solve the problem of the complexity of the traditional method for the design of those parameters, the model of the lunch of the system is constructed using energy method. Base on model construction, the parameter analysis, the model simplification and the parameter calculation are completed. The results of this method have been tested by system simulation. The simulation result shows that this method has definite physical sense and is simple and practical. It can be used to calculate the parameters of the launch of UAV and can provide the general scheme of launch system with design basis.
