metadata.fyp.dc.description.abstract: As aircraft flying, a lot of lift needed to ensure maximum thrust can be generated. However as lift increase, induced drag also will increase. One of the problems due to drag usually happen at the wing tip. Vortices will formed at the wingtip and create pressure above the wing. Therefore, reduce lift. In order to overcome this problem, various wingtip shapes are being applied at the wingtip. The purpose of the analysis is to analyse the efficiency of different wingtip shapes. From this analysis, flow visualize of wing with and without wingtip and various wingtip shapes by using CFD with reference drawing of Boeing 737’s wing, compare lift and drag ration and analyse the efficiency of wing with and without wingtip and various wingtip shapes. The analysis involving wing without wingtips shapes, wing with wingtip shapes and three different types of wingtip shapes; blended winglet, raked wingtip and wing fence by using Boeing 737’s wing as a reference drawing. All of these will be analysed by using CFD. From the analysis, the efficiency can be determined by comparing lift and drag ratio. From the analysis, wing without wingtips shapes has the highest lift and raked wingtip has the least turbulence. By comparing lift and drag ratio of all five, it shown that raked wingtip has the highest lift and drag ratio which is 0.768055. Therefore, raked wingtip is the most efficient wingtip shapes.
