Hydrodynamic Fin-type Vibration Propulsive Device

The present invention pertains to te field of water transport actuators, and it can be used for motion excitation of ships, underwater robotic fishes, motorboats, etc. Its objective is to simplify design of the fin and to increase efficiency of propulsive device. The proposed propulsive device is equipped with drive, transmission mechanism and double fin with varying surface area. Each fin of the propulsive device is made from two thin-walled plates mutually connected by hinge. Additionally prestressed torsion spring is mounted between both plates in hinge zone, and both plates of the fin are equipped with stops, which limit relative rotation of plates in outside from the fore-and-aft axis of floating vehicle, but don't limit relative rotation of plates in opposite direction.
