The research on the high-lift device of the laminar wing is of great significance for the drag reduction and noise reduction during flight. This article reviews the development needs of green aviation for drag reduction and noise reduction, introduces the technical characteristics of the high-lift device and laminar wing, and explains how the high-lift device on the leading and trailing edge of the laminar wing realizes the expansion of the laminar area. Introduce the structural adjustment methods, including the application of structural shapes, mechanisms and auxiliary devices. Analyze the technic that needs to be studied to achieve the adaptive adjustment of the high-lift device, and summarize the direction and ideas of the future research.
