并联构型辅助燃油系统性能分析
|
摘要
本文基于FloMASTER对一种以客舱增压空气作为压力源进行燃油转输的并联构型辅助燃油系统进行了建模。在此基础上,对不同飞行高度下的增压转输性能,以及不同加油压力下的加油性能进行了计算分析。结果表明:随着飞行高度的增大,燃油转输压差增大,辅助油箱完成燃油转输的时间缩短。随着加油压力的提高,辅助油箱完成加油的时间不断缩短,但随着加油压力的升高,完全加油时间缩短的趋势逐渐减小。
A parallel configuration auxiliary fuel system was modeled based on FloMASTER. The pressurized cabin air was used as the pressure source for fuel transfer. On this basis, the pressured transfer performance at different flight altitudes and the refueling performance at different refueling pressures were calculated and analyzed. The results show that with the increase of flight altitude, the pressure difference of fuel transfer increases, and the time for auxiliary fuel tank to complete fuel transfer is shortened. With the increase of the refueling pressure, the time for auxiliary fuel tank to complete refueling is shortened. However, The extent of time reduction is gradually weakened.
