Underwater propeller device with pulsed jets
The present invention refers to a device, which is autonomous or which can be associated with another structure, for propulsion in a liquid environment, which can be used in many fields, from underwater exploration to checking on and maintaining equipment to mini-invasive surgery. More precisely, the invention relates to an underwater propeller device comprising: a bladder body completely made of a soft material, developing along and around a central longitudinal axis, defining an internal chamber between a dorsal wall and a ventral wall; in said bladder body, an inlet opening and an outlet opening of a liquid in and out of said chamber, arranged at a longitudinal end of the body; and drive means for driving a contraction of said bladder, arranged on said dorsal wall and comprising a mechanical connection with said ventral to cyclically attract the ventral wall to the dorsal wall, thereby causing a pulsed ejection of a propeller jet from said chamber through said outlet opening.

Abstract

The present invention refers to a device, which is autonomous or which can be associated with another structure, for propulsion in a liquid environment, which can be used in many fields, from underwater exploration to checking on and maintaining equipment to mini-invasive surgery. More precisely, the invention relates to an underwater propeller device comprising: a bladder body completely made of a soft material, developing along and around a central longitudinal axis, defining an internal chamber between a dorsal wall and a ventral wall; in said bladder body, an inlet opening and an outlet opening of a liquid in and out of said chamber, arranged at a longitudinal end of the body; and drive means for driving a contraction of said bladder, arranged on said dorsal wall and comprising a mechanical connection with said ventral to cyclically attract the ventral wall to the dorsal wall, thereby causing a pulsed ejection of a propeller jet from said chamber through said outlet opening.
