燃油气液比对飞机吸力供油的影响研究

摘要

吸力供油是民用飞机燃油系统的基本功能，燃油气液状态是影响吸力供油能力的关键性因素。以某型飞机为例，通过严格的试验方法，对吸力供油能力进行了验证，并以试验数据为基础，对燃油气液比进行计算，分析了其产生的影响。研究结果可用于指导飞机燃油系统设计和发动机性能评定。%Fuel vapor and liquid condition is the critical factor for the suction feed, which is the basic function of the fuel system for civil aircraft. The suction feed function for some aircraft is verified as an example in this paper with the strict flight test method. Based on the test data, the vapor and liquid ratio ( V/L) is calculated and the corresponding effect is analyzed. The research can be used on guiding aircraft fuel system design and engine per-formance evaluation.
