鱼雷热动力推进系统的闭环控制研究

Research on Closed Loop Control of Torpedo Heat Engine Propeller System

对鱼雷热动力推进系统实施闭环控制是提高武器效能的需要。本文提出了可能应用于开式循环活塞发动机系统 的四种闭环控制方案,即比例压强阀、比例流量阀、比例节流阀和变量燃料泵方案,从系统物理特性、可实现性、系统效 率以及运行安全特性等角度出发,对其进行了分析对比,认为变量燃料泵方案是最适合于鱼雷热动力推进系统实施的闭环 控制方案。

Closed loop control must be used for torpedo heat engine propeller system in order to improve the tactics efficiency of weapons.Four control schemes,pressure relief valve,flow control valve,restrictive valve and variable displacement fuel pump were brought forward,which can be used for open thermal cycle combustion engine system of torpedo.Based on the character of physics,realization,system efficiency and security,these schemes were analyzed and compared.The result shows that the variable capacity fuel pump scheme is the best one.
