摘　　要：通过研究无动力运载器水下弹道特性,确定无动力运载器在出水点处应满足的速度、角速度、姿态角及出水点位置等指标要求,从而使导弹和运载器安全分离,并确保舰艇安全。由于水下动力学环境复杂且随机,无动力运载器又属于无闭环控制,因此无动力运载器在水下受波浪、海流、射速、射深等多因素影响,使得无动力运载器水下弹道的设计十分困难。为此,对无动力运载器的进行了动力学建模,利用matlab等软件对水下弹道进行了仿真计算,重点分析了无动力运载器不同发射速度和发射深度的参数值对运载器出水速度、俯仰姿态及出水距离等因素的影响规律。结果表明:出水俯仰角随发射速度的增大而变小,随发射深度的增大而变大;出水合速度随发射速度和发射深度的增大而变大。研究结果对水下运载器整体设计和弹道设计具有一定参考作用。This paper focuses on researching on the underwater ballistic of no power carrie. If at the water point, no power body establishes velocity, angular velocity, attitude angle, and effluent point position indicator require- ments, the missile and carrier will be separated successfully and the naval vessels will be safe. Because the dynamic environment under the water is complex and random, and no power carrie belongs to no closed-loop control, so it is very difficult to makes trajectory design for no power carrie with influence of wave, current, speed, injection depth and other factors. So this paper made parameter on no power cartier, simulated the submarine trajectory with MAT- LAB software and analyzed regulation with which different parameter values on the emission speed and depth have an effection on water velocity and distance and pose in the pitch. The simulation results show that water pitching angle reduces with the increasing of emission speed and increases with the increasing of emission depth, and launching speed increases with the increasing of emission speed and depth. The conclusion has certain reference function in de- signing trajectory of no power cartier.
