摘　　要：通过分析某型单发夹角式火箭助推发射无人机从助推火箭点火到爬升至安全高度的运动过程,建立了某型无人机发射起飞全阶段的动力学模型,运用Matlab编写了发射起飞段的飞行仿真程序。仿真结果与实际飞行结果对比分析表明,仿真预测的结果与该型无人机的实际飞行结果较为吻合。此外,探索了一种准确、快速地确定非标状态下安全发射包线的方法,提高了仿真程序的通用性和快速性。By analyzing the motion process of a certain single rocket included angle booster launching unmanned aerial vehicle（ UAV） from the booster rocket ignition to climb to safety height,a dynamic model of the UAV launching stage was established,the flight simulation program of the launching stage was written in Matlab,the simulation results were compared with real flight test results and the comparison showed that the consistency between the two results is fairly good. In addition,this paper explores a method which can accurately and quickly determines the safety launch envelop in the non-standard state,and improves the universality and rapidity of the program.
