Abstract

The invention relates to a flow converter for propellers of marine crafts, consisting of a tube or enveloping casing (1) of the propeller and a plurality of back radial thrust blades (2) that form a stationary assembly which is rigidly fixed to the stern of the craft or the tail of the motor (onboard or outboard) by means of a dismountable coupling. The combined action of the thrust blades, which have a slight warping (4) on the face close to the propeller, the special hydrodynamic shape of the inner face of the tube or enveloping casing and the gradual increase in diameter (5) on the turning plane of the propeller, transform the secondary flows generated in the propeller into axial flow providing thrust, propulsion performance being thus increased by approximately 50 %.
