AQUATIC PROPELLER WITH BLADES HAVING LATERAL AND DORSAL NOZZLES, WITH DIMINISHED HYDRODYNAMIC RESISTANCE

摘要

The invention relates to a naval propeller with blades providing the diminishing of the hydrodynamic resistance upon smooth propeller operation. According to the invention, the propeller comprises some blades () wherein one or several nozzles () are cut for the intake of the incident fluid, laterally for the ejected fluid and dorsally for the ejected fluid, the fluid streams flowing through the nozzles () being joined in a functional assembly by means of some internal channels cut into the blades ().
