摘要：
The installation of winglet is an important method to reduce the induced drag, but if the winglet design is not good enough will increase weight and drag, and result in reducing the lift-drag ratio of the plane. With the small jets as the research object, referred the wing of "longhorns" to build basic airplane wing, with installation of fusion winglet. According to the 5 parameters of winglet established test models by the use of orthogonal test method, the test models were aerodynamic simulated and analyzed by Fluent, and studied the impact of 5 parameters on the lift-drag ratio. The results showed that: the setting angle has the greatest impact on the aerodynamic performance of winglet, and the model of winglet has better lift-drag characteristic which was optimized by orthogonal test, thus to provide theoretical basis for parametric design of winglet.
