The Aerodynamic Characteristics of Winglet and Effect on the Performance of the Flight

Abstract:

Winglet is a kind of advanced technology. It is similar to the small wings of the wing surface, below approximately perpendicular to the wing surface, as long as the curvature and installation direction of winglet matched the local airflow properly, the winglet on the inward side force can inhibit the airplane wing tip vortex, reduce the induced drag. This paper introduces the cause of induced drag and the aerodynamic characteristics of the winglet,Further discusses the influence on plane flight performance, including level flight ,climbing and gliding. This knowledge will be of practical significance for guiding flight.
