摘要/Abstract

摘要： 同心筒水下垂直发射导弹时潜艇是具备一定艇速的，相当于给弹体增加了侧向横流，其影响在弹体出筒阶段尤为显著，带来发射安全性和弹体结构载荷相关的诸多问题。为获得在时间和空间维度上置信度更高的导弹出筒载荷特性，并采用较少的假设，首次提出并建立了考虑适配器弹性约束和弹体三自由度的耦合求解流场和弹体运动的非定常数值模型。阐述了筒口气泡弹性对弹体载荷特性的影响，同时获得了出筒过程中的弹体运动、受载及适配器变形情况。仿真结果表明：由艇速产生的横流造成的振荡特性对导弹发射产生不利影响。结果可为同心筒水下垂直发射安全性评估和弹性结构设计提供研究方法。

Abstract: A cross flow is applied on a missile, which has a great influence on the stage of out of tube, when a missile is launched from the concentric canister launcher during the movement of submarine. This leads to a series of launching safety and load problems. In order to obtain a higher degree of confidence of load characteristics out of tube both in time and spatial dimensions and use the less hypotheses, an unsteady simulation model which can solve the flow field and missile motion in consideration of the adapter elasticity and 3 DOF motion of missile is proposed and established by the first time. The effect of bubble elasticity on the load characteristics is analyzed. The motion parameters, load characteristics and adapter deformation during the launching of missile from launch tube are obtained. The results show that the oscillation resulting from the cross flow has an adverse effect on missile launching.

Key words: ordnance science and technology, underwater launching, load characteristics, coupling calculation of flow field and motion, adapter elasticity
