Fin-Based watercraft Propulsion system

摘要

A watercraft comprises a motor, an inertial mass, and a fin. The motor oscillates the inertial mass about an axis, producing a torque reaction on and oscillation of the motor. Oscillation of the motor is communicated to the fin, producing thrust.

1. A watercraft comprising a fin, a motor, and an inertial mass, wherein the inertial mass is supported symmetrically about a central axis of the motor, wherein the motor cyclically counter-accelerates the inertial mass and is subject to a torque reaction caused thereby, wherein the torque reaction on the motor is communicated to the fin, resulting in a translation of the fin through a surrounding thrust fluid, wherein the translation of the fin though the surrounding thrust fluid produces thrust.
