Research on the Status and Key Technology in Morphing Airfoil of Adaptive Wings

Abstract

The adaptive wing has enormous potential for application. It is an inevitable trend of future aircraft design and has received extensive attention. This paper focuses on the adaptive compliant leading edge, the adaptive compliant trailing edge and the morphing thickness wing, in which the principles of morphing are discussed in detail. Skins, actuation and research method are summarized. At the same time, the future trend is presented. And the key technology that adaptive wing needs to be solved urgently is put forward, including flexible skin design, adaptive actuation design, collaborative controller design and distributed sensor net, which can provide some technical reference for the design and implementation of adaptive wing structure.
