A variable displacement type pistonpump discharges different flowrate by changing swashplate angle, namely the flowrate is approximatelyproportional to the swash plate angle. Therefore, thechange characteristics of flowrate are the same of thesetwo types piston pump.References1. Yang YS, Nie SL, Zhu YQ (2007) Reaction thrust of submergedwater jets.

分析和设计的水泵与蓄能器吸收在高速喷水推进系统压力脉动
摘要：大容量和高压活塞水泵通常用于高压电源喷水推进系统(HWPS)。当活塞式水泵工作,一些流量和压力脉动生成,然后创建大推力脉动和飞机吗噪音。在大多数情况下,一个蓄电池充电常数压力气体总是安装在出口附近的水泵吸收流量和压力脉动。如果HWPS需要改变推力,旋转和输出水泵的压力将会改变。因此,的功能蓄电池吸收流量脉动和压力脉动会削弱。为了解决这个问题,一个有效的意着使多个蓄电池充电不同的压力与出口商会联系本文提出了水泵。根据水泵的结构模式,工作压力HWPS和许用压力脉动的价值因素,一些关键的参数,可以由最优首先,提出计算方法如数量蓄电池的容量和充电的压力蓄电池。最后,仿真和实验结果透露,三双蓄能器的参数从实际工作是优化计算吗条件,可以使压力脉动的因素关于许用值,当工作压力HWPS变化的范围。
