摘要
采用AMESim搭建直升机燃油箱冲洗惰化的系统模型,对燃油箱模型进行简化。综合考虑完整飞行包线的高度、耗油率、载油率、富氮气体浓度及流量,系统地计算多条典型飞行包线下的富氮气体需求量以及完成地面初始惰化的富氮气体需求量。针对仿真结果,对不同飞行包线下的富氮气体需求量、完成地面初始惰化的富氮气体需求量进行分析,并对不同载油量初始惰化时间进行评估。其结论可为直升机燃油箱惰化系统的工程设计提供参考。
AMESim was used to build the helicopter fuel tank washing inerting system model,and the fuel tank model was simplified.The height of flight envelope,fuel consumption rate,fuel load rate,nitrogen-rich gas concentration and flow rate were comprehensively considered.The system calculated the nitrogen-rich gas demand under several typical flight envelope and the nitrogen-rich gas demand required to complete the ground initial condition.Based on the simulations results,the requirements of nitrogen-rich gas under different flight envelope and the initial inerted nitrogen-rich gas on the ground were analyzed,the initial inerting time of different fuel loads was also evaluated,and the conclusions could provide a reference for the engineering design of helicopter fuel tank inerting system.
