摘要：
Aircraft icing has a significant impact on flight safety，as ice accumulation on airfoils and engines can cause aircraft stalls. Developing anti-icing technology that can adapt to harsh and cold environment presents a challenge. Here，we propose a new anti-icing skin with micro-nano structure inspired by the bamboo leaf called Fargesia qinlingensis. A multilayer non-uniform height （MNH） micro-nano structure is proposed based on the Fargesia qinlingensis surface structure. The anti-icing mechanism of the MNH micro-nano structure is revealed. The flexible large-area MNH micro-nano structure is fabricated based on hierarchical assembly method. Compared with the smooth surface，the ice adhesion strength of the prepared bio-inspired surface is reduced by 80%，indicating that the MNH micro-nano structure inspired by Fargesia qinlingensis has ice-phobic effect. Based on this，an anti-icing hybrid skin based on bionics and electric heating is developed. The anti-icing hybrid skin has successfully completed the anti-icing function flight test on the UAV. To realize the effective anti-icing function under super cold conditions，the anti-icing hybrid skin has been applied on a certain type of UAVs. The bio-inspired anti-icing skin has broad application prospects in large transport aircraft，helicopters，wind power generation，and high-speed trains. © 2023 Nanjing University of Aeronautics an Astronautics.
