Abstract
Aerial-aquatic vehicles are capable to move in the two most dominant fluids, making them more promising for a wide range of applications. We propose a prototype with special designs for propulsion and thruster configuration to cope with the vast differences in the fluid properties of water and air. For propulsion, the operating range is switched for the different mediums by the dual-speed propulsion unit, providing sufficient thrust and also ensuring output efficiency. For thruster configuration, thrust vectoring is realized by the rotation of the propulsion unit around the mount arm, thus enhancing the underwater maneuverability. This paper presents a quadrotor prototype of this concept and the design details and realization in practice.

空中水族箱能够运行在两种最主导的液体中,这使得它们对于广泛的应用更加具有前景。我们提出了一种原型,其特殊设计用于推进器和推力器的配置,以应对水和空气液体性质的巨大差异。对于推进器,通过使用双速推进器切换不同的介质,可以提供足够的推力,并确保输出效率。对于推力器配置,通过推进器的旋转实现推力矢量,从而提高水下机动性能。本文介绍了这个概念的quadrotor原型,以及设计和实现细节。
