摘要
基于AMESim仿真软件,建立直升机燃油箱地面冲洗惰化模型以及全包线冲洗惰化模型。针对进气口进气流量、进气口富氮气体浓度等因素,分析了单舱燃油箱惰化基本规律,并通过仿真得到直升机全包线惰化氧浓度变化情况。
Based on AMESim simulation software,this paper established a helicopter fuel tank ground flushing inerting model.According to the factors such as intake air inlet flow rate and inlet nitrogen-rich gas concentration,the inerting law of single-chamber fuel tank was analyzed,and the variation of inertial oxygen concentration in helicopter all-inclusive line was obtained through simulation.
