油箱惰化流量需求计算方法研究
Study on Calculation Method of Flow Requirement for Fuel Tank Inerting
摘要
Abstract
According to the characteristics of gas-component mixing in fuel tank vapor space, and considering the influences of several factors such as fuel loading rate, environment temperature, gas solu-bility in fuel, fuel vapor and nitrogen-enriched gas concentration, a mathematical model of fuel tank iner-ting is established by using the numerical integration method.The correctness of the model is verified by the experimental data published in related literatures.On this basis, This paper researches on inerting flow requirements for aircraft taxiing -climb and subducting-descent stages, and analyzes the impact of fuel loading rate, nitrogen-enriched gas concentration, temperature and other factors on the inerting flow re-quirements.The study can provide theoretical support for design of the aircraft fuel tank inerting system.关键词
