Composite beam type wing surface structure

The invention relates to a composite beam type wing surface structure, in particular to the design of a high-load thin airfoil type missile wing structure. An upper metal box-shaped part and a lower metal box-shaped part are assembled through connecting holes. After assembling is completed, a surface A is attached to a surface C, and a surface B is attached to a surface D; the metal box-shaped parts are inserted into a metal joint for close attachment; metal box-shaped part connecting holes and metal joint connecting holes are in bolted connection; other lap joint positions are connected through rivets. The connecting strength of a wing spar and the metal joint is improved, the force transferring paths for connecting a skin and the joint are increased, and the purpose of force transferring of the high-load thin airfoil type missile wing is achieved.
