“…Huang Z F, Lu X Z & Yu G C, stability analysis and transition prediction of sweep angle 25 degrees are performed by solving classical O-S equation (LST), extended O-S equation (EOS) and linear throw stability equation (LPSE) [2]. Lifang ZENG, Liu LIU, Xueming SHAO, Jun LI, a numerical simulation method combined with a structured moving offset grid is used to solve the fluid [3]. Lance W. Traub, Samarth M. Chandrashekar, wind tunnel model tests are built to replicate sweep angles of 0,45 and 60 degrees, and it is discovered that aerodynamic characteristics have a substantial influence on the cosine of the leading-edge sweep angle and the square root of the flap height [4].…”

With the development of science and technology, more and more civil and military aircraft have adopted swept-back wing shapes. this paper explores the relationship between the angle of swept-wing and the lift, drag and lift-drag ratio of the aircraft, and expounds it in combination with the actual swept-wing aircraft, such as Boeing737 and MIG-23 to find the best sweep angle of the aircraft in the appropriate range and analyze the effect of swept wing angle on flight speed. This paper studies and analyzes the data through literature retrieval and data processing and cites data models from many academic journals. The experimental data are mainly derived from computational fluid dynamics and wind tunnel simulation. This paper finds that a wider sweep angle can result in better aerodynamic performance, suited for supersonic flight, while a smaller sweep angle can result in a better lift-drag ratio, it is suitable for takeoff and landing of aircraft and low-speed flight attitude.
