摘　　要：以某型飞机机翼气动分布载荷和结构重量为基础,研究气动载荷压心外移对机翼结构重量的影响,得到了气动压心外移量与机翼结构增重之间的函数关系。这个结论可以为其他型号的民机机翼设计提供参考依据。In this paper, the effect on the wing structure weight due to the location changing of the aerodynamic center is studied based on re- searching the wing aerodynamic load distribution and structure weight of one civil aircraft. The simple relation between the wing aerodynamic center moving distance and the wing structure weight increase is formulated. The conclusion can provide some reference for civil wing design of other aircraft.
