摘要

摘要: 通过在筒口喷射燃气射流形成稳定气幕, 可降低水下航行器发射出筒载荷, 提供良好的弹道环境。文中针对筒口燃气射流流量及提前喷射对航行器出筒载荷的影响, 建立了非定常多相流场模型, 分析了筒口气体射流分布规律、航行器表面压力和弯矩载荷, 对比分析了不同喷射流量、喷嘴位置及提前喷射下的出筒降载效果。结果表明, 喷射燃气形成的气幕能够有效降低航行器出筒载荷, 增大燃气喷射流量、均衡布置喷嘴位置以及提前喷射等措施有益于提升降载效果。

Abstract: The stable gas curtain formed by gas jet at the launch tube outlet is conducive to the reduction of outlet loads during launch of undersea vehicle and to the better trajectory environment. In this paper, an unsteady multiphase flow field model is established to analyze the effects of the flow rate of gas jet at the tube outlet and the early jet on the outlet load of undersea vehicle, the distribution law of the gas jet at the tube outlet, and the surface pressure and bending moment of the vehicle. The outlet load reduction effectiveness under different gas flow rate, position of nozzles and early jet are compared. The results show that the outlet loads can be effectively reduced by the gas curtain, and the measures such as increasing the flow rate of gas jet, uniformly laying the nozzles and early jet are beneficial to the load reduction
