摘要

The technology of high-altitude long-distance gliding UUV is a blend of high-altitude volplane and underwater voyage,Segment of ballistic deceleration is an important part of the trajectory process of high-altitude long-range gliding UUV.The six-degree of freedom motion equations of the UUV are established.The simulation and calculation of the deceleration trajectory of the UUV are accomplished in the Matlab/Simulink environment.Inverse deceleration rocket program is adopted to realize the deceleration of the UUV.The initial conditions are set up based on the requirements of UUV water entry.Simulation results show that the UUV is capable of meeting the requirements of UUV water entry,proved the feasibility of the program.Besides,elements as size of the anti-thrust,time of reverse thrust action and location of rocket installation that affect the section ballistic deceleration are simulated and analyzed,having the guiding significance for the further studies.%高空远程滑翔UUV技术是一种集高空滑翔与水下航行于一体的综合技术研究,减速段弹道是高空远程滑翔UUV弹道流程中的重要部分.通过建立高空滑翔UUV的六自由度数学模型,在Matlab/Simulink环境下对减速段弹道进行了运动仿真与分析.采用火箭反推减速方案对UUV进行减速,根据UUV入水条件要求设置初始条件,仿真结果显示UUV能满足入水条件要求,证明了此方案的可行性.并对影响减速段弹道的因素:反推力的大小、反推力作用时间、反推火箭安装位置进行了仿真与分析,对以后的进一步研究具有指导意义.
