Abstract
The wing, one of the most important parts of aircraft, always requires sophis-ticated design to increase lift, reduce drag and weight. For modern fixed-wing UAV, extending cruising time is always a requirement for the overall design. Designing a most light wing that can match the requirements of work condi-tions is desired. In this work, according to the work conditions, we compare several types of wing and chose beam-type wing. Then we made the detailed design and optimization to reduce the weight of wing. At last, we draw the 3D model for potential realistic production.
Highlights
One of the most crucial parts of an aircraft is wing
The following design can be obtained: 1) The beam type wing structure is adopted, and the beam is on the 1/4 string length
2) In the real wing structure, there need to be flapped and aileron, so the web is at the 85% string length
Summary
One of the most crucial parts of an aircraft is wing. The quality of the wing design determines the overall performance of the aircraft to a large extent [1]. The task of structural design is to design a specific wing structure, which can meet tactical technical requirements or develop the requirements of the contract task. This includes the plane shape of the wing surface, airfoil configuration, the relative position of the wing body and the location of the interior of the wing. Other wing structures are their combination or development [2]
