大型运输机机翼弯曲载荷计算

Estimation of Wing Bending Loads for a Large Transport

简要叙述了飞机平飞时影响机翼弯曲载荷的主要因素;重点介绍了机翼升力、机翼油箱燃油重力、机翼结构重力沿翼展分布数学模型的建立和机翼弯曲载荷计算公式的推导过程;所述方法虽然是针对大型运输机提出的,但对其它类型飞机同样适用。

The major factors which influence the wing bending loads (bending moments) of a large transport are introduced briefly. The report is in focus on establishing a method of calculating wing loads spanwise distributions caused by wing lift, fuel weight, wing structural weight,and powerplant weight by using the typical analytic functions .The method presented herein is applicable not only to a large transport but to other types of aircraft as well.
