Abstract: The Paper mainly focusing on the characteristics and properties of the wing with winglets. In worldwide all aircraft manufacturers try to improve the efficiency of the Aircraft mainly due to increased operating costs and environmental problems. During cruise condition of a commercial Aircraft, the lift-induced drag is typically 40% of its total drag and it is nearly 85% during take-off configuration. So, it is essential to present the concepts which help to reduce the induced drag. Use of wingtip devices is one effective way to reduce the Induced drag formation. So here a study is done on using winglets and observed the properties of the wing.
