The optimization design of winglet for civial aircraft
摘要
Abstract
Improving the performance of civil aircraft mainly depends on drag reduction.On the condition of cruise, the efficiency of reducing the whole plane's drag will be improved greatly if the induced drag of the wing can be reduced.In this paper, based on the civial aircraft pure wing, winglet is used to reduce the induced drag.Besides, the winglet's shape is optimized with the objective of reducing drag and the flowing mechanism is analyzed to make preparation for further study of winglet design.关键词
