Embodiment Construction
[0020] The present invention will be described in further detail below through specific embodiments and in conjunction with the accompanying drawings.
[0021] The steps of the present invention include:
[0022] Step 1. Different from the previous design of increased wingtip, which mainly uses winglets to block the vortex flow around the wingtip, first establish a new theory that uses the reverse vortex around the wingtip to reduce the vortex flow around the wingtip. The new vorticity calculation formula is:
[0023] Γ 总 =Γ 翼尖 -Γ 增升
[0024] After the design of the special shape of the increased wing tip, the circulation of the wing tip vortex can be partially offset, thereby reducing the loss of the three-dimensional flow around the wing tip, and achieving the purpose of reducing the overall aircraft resistance and increasing the overall aircraft lift;
[0025] Step 2, select the appropriate wing tip average sweep angle according to the aircraft design flight M number, ...
