Abstract
An underwater device using a reaction propulsion system. The initial flow entering by a front end turbine (1) is divided into two laminar, partially divergent flows (2) enabling the diver to place himself in the wake of the device. The power supply (3) is built into the device or is externally attached to the diving material, and an electrical cable (4) provides the electric power supply. The novel shape of the propulsion system makes it a handy and efficient device, especially suitable for underwater diving.
Claims12
Electric propulsion device for underwater diving, comprising a body extending in the direction of a longitudinal axis from a forward end to a rearward end, said body including a hydrodynamic propulsion system for propelling said device underwater, said body lying in a displacement plane and having an inlet opening at said forward end defining a first fluid flow path, and two divergent fluid flow paths each of which extends from said first fluid flow path to said rearward end at respective lateral positions in relation to said longitudinal axis in said displacement plane, such that in use, a diver extends in the direction of said longitudinal axis in said displacement plane, and each divergent fluid flow path flows in the direction of said longitudinal axis on either side of said diver, and in said displacement plane.
