ABSTRACT:
A propulsive force for propelling different types of water vehicles is developed by four paddles mounted on the planetary gearbox which is rotated by the transversely oriented driving shaft. Each paddle has, preferably, two perpendicular to each other balanced blades and is rotated simultaneously around the axis of the driving shaft and around the axes of the output shafts of the planetary gearbox. During each turn of the driving shaft, four propulsion strokes are exerted consecutively. Each propulsion stroke is exerted by four blades which are moving along the specific curved paths with acceleration and deceleration caused by changing their circumferential velocity. Both sides of the blades are used consecutively as working surfaces. Optionally, each paddle can have one blade and a counterweight. The driving shaft can be oriented horizontally or vertically and disposed together with the planetary gearbox and the paddles under the water level or over the water level. It is rotated by an internal combustion engine or by any other driver. The propulsion apparatus can also be used in the outboard engines instead of the conventional screw propellers.
