Abstract
A device for generating a thrust in a liquid utilizing rotating cylinders. The cylinders are mounted on a rotatable hub and rotate about their own axes relative to the hub. The relative rotation follows, preferably, a sinusoidal path for producing the thrust, and in particular, each cylinder undergoes a reversal in its direction of rotation after each half rotation of the hub. A common control bar is included which is connected to each cylinder and eccentrically with respect to the axis of rotation of the hub so that the points of reversal and the direction of thrust can be adjusted.
