摘要

摘要: 程控阀能否在应急条件下完成发射任务是保证战时鱼雷发射成功与否的关键。为探究阀芯在应急条件下能否保证较好的发射品质, 文中运用FLUENT对3种阀芯结构的内流场进行了有限元仿真, 分析得出了双梯形-双矩形阀芯结构能够有效减少能量在通过阀芯时的损耗, 从而可以有效提升发射品质, 可为进一步优化发射过程能量的瞬态注入与控制, 进而降低发射过程的瞬态噪声提供参考。

Abstract: A program-controlled valve, which can complete launch mission in emergent condition, is vital to ensure successful launching of a torpedo in war. To explore whether the valve core can keep good launching quality in emergent conditions, the finite element simulation software FLUENT is employed to simulate the internal flow fields in three kinds of valve core structures. Contrast analysis show that the double trapezoidal-double rectangular valve core structure can effectively reduce the loss during energy going through the valve core, hence enhance launching quality. This research may provide a reference for further optimization of transient energy injection and control as well as reduction of transient noise during launching process.
