Simulation Study on Performances of One Helicopter Fuel Jet Pump Based on Flowmaster

在分析某民用直升机燃油系统利用引射泵进行转输的原理基础上,利用一维流体仿真软件Flowmaster对引射泵进行了仿真。将仿真结果与试验数据进行比较,表明模型及参数设置可行。利用此模型分析了此引射泵的喷射特性,并对引射泵性能特性的影响因素进行了仿真研究,从而为引射泵的设计和使用提供参考。

Based on the analysis of the principle of the transmission of a civil helicopter fuel system using the ejector pump, the one-dimensional fluid simulation softw-are Flowmaster is used to simulate the ejector pump. The simulation results are compared with the experimental data, indicating that the model and parameter settings are feasible. The injection characteristics of the ejector pump are analyzed by this model, and the influencing factors of the perfor^nance characteristics of the ejector pump are simulated, so as to providereference for the design and application of the ejector pump.
