摘要/Abstract

摘要： 潜射导弹通常采用燃气—蒸汽弹射装置发射，弹尾离筒阶段筒口发生强烈的水-气交互作用，形成筒口气泡，该气泡的发展过程对发射平台会造成不利影响。采用CFD软件FLUENT对导弹离筒过程筒口气泡的发展及其对发射平台的影响进行了数值模拟。然后，给出了艇体不同位置压力脉动规律及其受发射深度的影响规律。仿真结果表明，压力监测数据与实验测量结果吻合良好，验证了研究方法的有效性。

Abstract: Submarine launched missiles are usually ejected by a gas-steam ejection system. In the separating process of missile tail and canister outlet, there is a strong interaction between water and gas, and a cavity is formed in front of the canister outlet. The cavity’s development affects the launch platform. CFD software FLUENT was used to simulate the process of cavity development and its effect on the launch platform. The pressure pulsations on the different places of the submarine surface and their effect on launch deep were affected by depth were investigated. The simulated result shows that the simulated data is agreement with the experiment data, and the investigation method is valid.

Key words: hydromechanics, underwater launch, outlet cavity, launch platform, pressure pulsation
