摘要

摘要: 围绕水下垂直齐射伴随的多相传热传质流动以及运动耦合过程，建立涵盖多相流动、细长体运动以及适配模块变形载荷等在内的数值计算模型，对齐射扰动特性进行研究分析。结果表明:受流体载荷、适配模块变形载荷影响，细长体离筒横向位移和姿态等发生变化，在弹体轴向运动2倍弹长的发射过程中，齐射弹道横向位移可达01倍弹长，横向姿态角达到7°。此外，首发细长体发射后水倒灌及筒口气泡溢出过程对次发细长体发射时的筒口气泡形态和载荷状态产生显著影响，进而也会对其弹道产生干扰，在考察状态下，首发弹体与次发弹体离筒时横向角差异为01°，横向角速度差异达到75 (°)/s。

Abstract: Focusing on the multiphase flow with heat and mass transition and the motion coupling process of underwater vertical salvo, a numerical calculation model of multiphase flow, slender body motion and deformation load of the adapter module was established to study the characteristics of salvo interference. The results showed that the lateral fluid load and the deformation of adapter module influenced the launching trajectory significantly. In the course of launching, the lateral displacement reached 01 times the length of the body and the lateral attitude angle reached 7°. In addition, the flow backward and bubble overflow process of canister outlet after the launch of the first slender body had a significant influence on the bubble shape, load state of the second slender body, as well as the trajectory. In the current case, the difference of lateral attitude angle between the first and second launching bodies is about 01° at the leaving moment, and the difference of angle velocity reaches 75 (°)/s.
