旅客机燃油质量分布特性计算方法研究

Study on Calculating Mass Distribution Characteristics of Fuel in Passenger Airplane

飞机燃油质量分布特性计算是一项复杂困难但又是十分重要的工作。本文采用将油箱分割成单元斜六面体的方法解决了油箱形状的描述问题，采用将燃油切片的方法解决燃油质量分布特性的计算问题。根据本文方法编制的计算程序，已成功地用于某旅客机改型的燃油质量分布特性计算中。

The calculation of mass distribution characteristics of fuel in tanks is a difficult and complicated work. This paper solves the problem of describing the shape of tank by subdividing the tank into tapered boxes, and uses the slice method to calculate the mass distribution characteristics. The result shows the method is feasible.
