摘要
在研究论述飞机燃油系统设计中高空性的基础上,通过分析燃油的饱和蒸汽压的影响因素,给出了燃油饱和蒸汽压的计算公式和燃油的饱和蒸汽压力随温度的变化曲线,并给出了航空煤油能够保证的飞行高度;讨论了燃油系统的汽蚀问题;分带供油泵管路和无供油泵管路2种情况讨论了燃油系统高空性计算流程,并给出了具体的计算公式和图表。
Altitude performance of aircraft fuel system is studied by analyzing factors that affect the saturated vapor pressure of the fuel.The calculation formula of saturated vapor pressure of fuel and the changing curve of the pressure with temperature are established,and the flight height that aviation kerosene can guarantee is given.The cavitation problem in fuel system is also discussed.At last,the flow chart for altitude performance calculation of fuel system with or without fuel feed pump are also discussed.
