Description

Technical Field

[0001] The utility model relates to the technical field of aircraft wing structures, in particular to an aircraft combined wing spar structural component. Background Art

[0002] The aircraft wing spar structure is the main load-bearing component used to transfer concentrated loads. Suspension supports are installed on the wing spar to connect the rudder and control system. The wing spar structure is usually made of composite materials to reduce the structural weight, and the suspension supports are usually made of metal structures and assembled on the wing spar. In the case of densely arranged suspension supports, the composite wing spar is usually designed with a larger thickness to withstand larger concentrated loads, resulting in excessive structural weight. If the entire wing spar structure is made of metal materials, it will also cause the problem of excessive structural weight. For this reason, we propose an aircraft combined wing spar structure to increase the strength of the aircraft wing and reduce the weight of the aircraft wing body. Utility Model Content
