摘要

摘要:
为提高鱼雷等水下航行体高突防性能，针对金属水冲压发动机设计了多级推力方案，针对常规进水道总压损失显著问题，借鉴喉栓式变推力发动机结构，提出一种多分支分布式异形管路进水高效减阻进水方案，旨在实现高效减阻。通过理论分析与数值模拟相结合的方法，系统研究了管路布局、截面形状以及注水口分配对管路阻力损失的影响。结果表明：以二次进水管为例，与相同进水量的外部进水方式相比，分布式进水布局可使压降降低50%，引入异形截面后压降进一步降低22.45%，引入多分支进水口后压降进一步降低13.17%。综合来看该分布式多分支异形管路方案能够使进水在燃烧室轴向均匀分布，同时也能使压降显著降低85.62%。该研究为水冲压发动机的性能优化提供了一条技术路径。

Abstract:
To enhance the high-penetration performance of underwater vehicles such as torpedoes, a multi-stage thrust scheme was designed for metal water ramjet. For addressing the significant total pressure loss in conventional water intake channels, an efficient resistance loss reducing water intake scheme with a multi-branch distributed non-circular pipeline was proposed, inspired by the structure of pintle-type variable thrust motors. This scheme was designed to achieve highly efficient resistance loss reduction. Through a combination of theoretical analysis and numerical simulation, the effects of pipeline layout, cross-sectional shape, and water injection port distribution on pipeline resistance loss were systematically investigated. The results showed that, taking the secondary water inlet pipeline as an example, compared with an external water inlet method with the same water flow rate, the distributed water inlet layout reduced the pressure loss by 50%. Introducing a non-circular cross-section further reduced the pressure loss by 22.45%, and incorporating multi-branch water inlets further reduced it by 13.17%. Overall, this distributed multi-branch non-circular pipeline scheme enabled uniform axial distribution of water inlet in the combustion chamber while significantly reducing the pressure loss by 85.62%. This study could provide a technical pathway for performance optimization of water ramjet.
