The wing, one of the most important parts of aircraft, always requires sophisticated\ndesign to increase lift, reduce drag and weight. For modern fixed-wing\nUAV, extending cruising time is always a requirement for the overall design.\nDesigning a most light wing that can match the requirements of work conditions\nis desired. In this work, according to the work conditions, we compare\nseveral types of wing and chose beam-type wing. Then we made the detailed\ndesign and optimization to reduce the weight of wing. At last, we draw the 3D\nmodel for potential realistic production.
