Abstract

This paper describes a novel ultrasonic underwater thruster without any moving part. Our typical ultrasonic underwater thruster weighs only about 0.3mN, but can produce 5.6mN thrust, producing a thrust ratio of 19:1. The thruster moves forward by shooting out water jet stream backward through an acoustic streaming effect. To enhance the acoustic streaming effect, the self-focusing acoustic transducer (SFAT) is used. In this paper, two transducer structure designs and three electrode designs are described and compared.
