BUBBLE-GENERATING DEVICE FOR REDUCING FRICTION ON THE HULL OF A BOAT

摘要

The invention relates to a device for generating bubbles which are intended to be incorporated mainly into the turbulent boundary layer of the wetted surface of the hull of a moving boat. The invention consists of a multi-cell system which is affixed to the walls of the hull of the boat and which is equipped with at least one main circulation shaft which is traversed by two distribution conduits, namely: a first conduit (1) for pressurised water (preferably originating from the aquatic sailing environment); and a second conduit (2) for a pressurised gas (preferably air), said two conduits supplying multiple bubble-releasing cells in a sequential, parallel or combined manner.
