飞行中燃油面变化对飞机重心的影响研究

Study on the Impact of Fuel Surface Changes on the Gravity of Aircraft in Flight

针对飞行中燃油重心变化对飞机重心影响评估的需要,提出了一种基于油箱建模的分析方法。根据飞行中燃油的运动规律,提出了与油箱形状、尺寸、油量和油面角相关的燃油建模方法,以此为基础给出了油面变化对飞机重心影响的分析方法。通过对某型机的验证计算说明,该方法误差小,能够满足实际评估的需要。

Aiming at the need of the fuel centroid impact assessment of the aircraft, a new analysis method based on the fuel tank is presented. According to the motion law of the fuel in the flight, put forward with the tank shape, size, amount of oil and oil face angle of fuel modeling method, discusses the basic oil level changes influence on the center of gravity of the aircraft analysis method on the basis of the. Through the verification of a certain type of machine, the error of the method is small, and it can meet the needs of the actual assessment.
