摘　　要：现代战场上潜艇应用无人机进行侦查能够有效提的信息获取能力,丰富潜艇的作战形式。设计了一型无动力潜射无人机运载器,能够携带无人机从潜艇发射。使用Simulink建立该运载器的运动模型,并通过算例验证了该模型的正确性。之后分别改变运载器的发射参数和舵角参数分析其对运载器水弹道的影响。最后使用Isight软件集成水动力系数生成程序和弹道仿真程序,对运载器的外形参数和舵角参数进行优化,得到运载器最小出水速度。仿真结果表明,对于正浮力较大的潜射无人机运载器来说,通过合理舵角选择、外形设计和衡重参数设计可以减小运载器的出水速度并达到偏航距离的要求。以上的工作对潜射无人机运载器的设计能提供一些有益的参考。The use of UAVs for submarine reconnaissance on modern battlefields can effectively improve the information acquisition capability of submarines and enrich the warfare capability of submarines.An un-powered submarine-launched UAV carrier was introduced in this paper which can carry the UAV launch from the submarine.Motion model of the carrier was built in Simulink environment and a test example was used to verify the correctness of the model.Then the launch parameters and rudder angle parameters of the carrier were changed to analyze their effects on the water trajectory of the carrier.Finally,in order to minimize the water exit velocity of the carrier,Isight software was used to integrate the hydrodynamic coefficients generation program and the ballistic simulation program to optimize the shape parameters and rudder angle parameters of the carrier.The results show that for the submarine-launched UAV carrier with large positive buoyancy,the requirements of sufficient yaw distance and minimizing the water-exit velocity can be achieved by the suitable selection of rudder angle and reasonable design of rudder shape and primary parameters.The work in this paper provides some useful references for the design of submarine-launched UAV carriers.
