摘　　要：针对大深度环境水下发射技术需求,提出一种利用水压驱动两级提拉式水下新型发射方案。利用大深度环境高压水驱动两级活塞实现武器快速发射。建立武器出管过程动力学模型,开展高压水驱动方案原理验证试验,并与高压气体驱动方案进行了对比分析。研究结果表明:水压驱动与气体驱动方案的内弹道结果基本一致,高压水发射方案在大深度环境具有显著优势;加速度峰值出现在发射瞬时和级间转换过程,级间转换过程武器加速度存在显著的陡变现象;水下发射武器出管过程弹道预报结果得出,在发射水深100~500 m条件下,武器出管过程最大速度范围为7.4~15.3 m/s,最大加速度小于100 m/s 2;研究结果验证了水压驱动两级活塞式发射方案的可行性,为装置的进一步研制开发提供了设计依据。In order to meet the requirements of underwater launch technology in large deep environment,a new water-driven underwater launch device with two-stage piston is proposed.The launch device is driven by high-pressure water in large deep environment to launch projectiles rapidly.A dynamic model of projectile pulled out of launching tube is established,and the principle verification test using high-pressure water-driven scheme is carried out.And the test data are compared with those of the reference test using high-pressure gas-driven scheme.The results show that the interior trajectories of water-and gas-driven schemes are basically the same.The comparative advantage of the high-pressure water-driven scheme is very obvious in large depth environment.The peak acceleration appears mainly in two moving processes,namely the launching instant and interstage transition between two stage pistons.The acceleration of projectile motion changes sharply in the interstage transition.The trajectory predicted results show that the maximum velocity range is 7.4-15.3 m/s and the maximum acceleration is less than 100 m/s 2 under the condition of the underwater launching depth of 100-500 m.The results verify the feasibility of the underwater launch device of two-stage piston driven by water pressure,which provides the design basis for the further development of launch device.
