摘要
基于工程梁理论建立了联结翼结构重量特性分析模型,给出了联结翼结构详细的内力解答,研究了联结翼布局参数(包括掠角、反角、端板高度、载荷比)对于结构重量的影响。研究结果表明:联结翼布局的内力在前、后翼间重新分配,从而提高了结构效率。研究结果对联结翼结构设计具有一定指导意义。
A model with weight characteristics of the joined wing structure is established based on engineering beam theory, the internal force of the joined wing structure is given, and the effect of the sweepangle, the dihedral angle, the joint length and the load ratio on the structural weight is investigated. Resuits show that the structural efficiency of the joined wing is improved because of the internal force is redistributed between the fore wing and the rear wing. The results obtained in this paper are significative for the structural design of the joined wing.
