摘　　要：跨介质多旋翼潜空两栖航行器是以旋翼飞行器为基础设计的能在两种不同介质中航行的跨介质航行器,在出水/入水跨介质过程中,由于水空介质性质差异性大,旋翼在水空介质跨越中的性能尚未可知。为研究旋翼系统在跨介质过程中的性能变化,设计了一套旋翼跨介质试验系统,对旋翼系统在水空跨介质过程中的性能表现进行实验分析,并给出了旋翼拉力在地面效应和水面效应下的实验数据对比,发现了水面效应对旋翼拉力的减弱作用。The aerial-aquatic rotor vehicle is a cross-medium vehicle designed on the basis of rotorcraft and can navigate in two different media. Due to the large difference in the properties between water and air mediums, the performance of the rotorcraft in the water-air medium spanning process is still unclear. In order to study the performance changes of the rotor system during the process of trans-medium, a set of rotor cross-medium test system was designed, and the performance of the rotor system in the water-air cross-medium process was experimentally analyzed. The experimental comparison data of the rotor thrust under the ground effect and the water surface effect is obtained, and the weakening effect of the water surface effect on the rotor thrust is found.
