摘　　要：飞机燃油系统是飞机的核心系统之一,对飞机安全可靠飞行至关重要。为解决飞机纵向飞行时,因多油箱供油量分配不合理产生飞机质心的偏移问题,本文通过分析飞机供油原理,建立飞机纵向运动供油质心模型,在此基础上,采用复合形法根据飞机俯仰角和各油箱油量实时确定飞机的最优供油策略。仿真结果表明,给定飞机要求质心变化后,通过本文方法确定的供油策略能将飞机质心偏移量控制在合理范围之内,并实现了供油策略随要求质心的动态调整,方法具有理论和实际工程应用价值。The aircraft fuel system is one of the core systems of the aircraft and is essential to the safe and reliable flight of aircraft.In order to solve the problem of the offset of the aircraft centroid due to the unreasonable distribution of fuel supply from multiple fuel tanks during the longitudinal flight of aircraft,this paper analyzes the principle of aircraft fuel supply and establishes a fuel centroid model for the longitudinal motion of aircraft.On this basis,a complex method is adopted.The optimal fuel supply strategy of aircraft is determined in real time according to the aircraft pitch angle and the fuel volume of each fuel tank.The simulation results show that after the required centroid of a given aircraft changes,the fuel supply strategy determined by the method in this paper can control the offset of the aircraft centroid within a reasonable range,and realize the dynamic adjustment of the fuel supply strategy according to the required centroid.The method has theoretical and practical engineering application value.
