基于Flowmaster的压力加油冲击压力仿真研究

Study on Simulation for Wallop of Pressure Refuel Basing on Flowmaster

研究了基于Flowmaster软件的直升机压力加油冲击压力仿真建模,将仿真结果与试验结果比较,采用地面压力加油泵进行建模,仿真计算冲击压力值远较试验值大;据此,提出采用恒压源代替地面压力加油泵的建模方法,仿真计算冲击压力值与试验值相差10%左右,满足了直升机压力加油冲击压力的工程计算需要。

This paper studied a simulation model of pressure refuel system of one helicopter by Flowmaster software.Comparing the simulation results with the test results was that the wallop of simulation results was much bigger than the test's when building the model with the use of the ground pressure refuel pump.This paper suggested a way that the constant pressure resource replaces the ground pressure refuel pump.Comparing the simulation results with the test results was that the wallop of simulation results was about 10 percent of the test's with the use of this way.The way could suffice for engineer computation requirement.
