摘要
为突破传统排水型两栖车辆'阻力墙'现象,从蛇怪蜥蜴高速踏水机理出发,基于固体和液体高速作用动力学原理,提出了一种新型水面推进技术。其依靠仿生叶轮与水高速作用产生向上托举力,将两栖车辆托举出水面,进入高速滑行状态,从而避开'阻力墙'现象,实现快速突进。结合仿真分析和先期原理试验,验证此技术能够实现两栖车辆从排水状态进入高速滑行状态,从而大大减小水阻力,是一种有效的水面快速推进方法。
In order to breach the resistance wall phenomenon encountered by traditional am- phibious vehicle, this paper puts forward a new technique of propulsion by studying the treading water mechanism of a basilisk lizard and the theory of solid-liquid mutual action on high speed. It can lift amphibious vehicle upon the water into the high speed sliding status depending on the up- ward lift force produced by the high speed action between the bionic impeller and the water thus obtaining a high speed and avoiding the resistance wall phenomenon. Through simulation analysis and theory experiments in advance, it is validated to be an efficient technique which can make the amphibious vehicle into the high speed sliding status, reduce the water resistance and increase the velocity on water.
