Research Progress of the High-lift Device Design for Laminar Wing

Abstract

The lift device design of laminar flow wing can reduce drag and noise.By combining the low resistance laminar flow area with the high-efficiency lift device and adopting the effective shape design and appropriate structure selection,the expansion of laminar flow area during cruise and the improvement of lift effect during take-off and landing can be realized,and the body noise can be significantly reduced.According to the development needs of green aviation,the technical characteristics of laminar wing and lifting device are analyzed,the design method of the lifting device under the condition of laminar flow wing is described,the application status of structure shape,motion mechanism and auxiliary device is systematically introduced.On this basis,the key research contents for realizing the adaptive adjustment of the lifting device are summarized,and the future development direction and ideas of the lift device are given.
