The invention provides a method for reducing water surface takeoff resistance of an amphibious aircraft. The method comprises the step of reducing sliding resistance and solid-liquid adhesive force generated when the amphibious aircraft gets rid of the water surface during takeoff. A super-hydrophobic surface with a micro/nano structure and low surface energy is arranged on the surface of the amphibious aircraft; based on the technical scheme, a microstructure formed on the super-hydrophobic surface and extremely low surface energy form an air film by intercepting a large amount of air, so that the sliding performance of the amphibious aircraft is improved, and the sliding resistance reduction function is achieved; in addition, the contact area of water and the solid surface is small, the liquid adhesive force during solid-liquid separation can be reduced, the aircraft can be helped to break away from the water surface to take off, and the take-off weight of the aircraft is increased.
本发明提供了一种降低两栖飞机水面起飞阻力的方法,包括降低滑行阻力和起飞挣脱水面时的固‑液粘附力。在两栖飞机表面设置具有微/纳结构和低表面能的超疏水表面;基于本发明的技术方案,超疏水表面形成的微观结构和极低的表面能通过截留大量的空气形成气膜,从而增加两栖飞机的滑移性能,实现滑行减阻功能;此外,水与固体表面的接触面积低,可降低固‑液分离时的液体附着力,有助于飞机挣脱水面起飞,提升飞机的起飞重量。
