Water-jet propeller mounted in partially submerged disk hydrofoil-float

摘要

A water-jet propeller consists of a pump, a water intake nozzle and an outlet nozzle. The engine has at least one horizontal wheel rotor of large diameter with blades of optimized shape. The wheel is mounted in a cavity of partially submerged elongated and tapered at the end hydrofoil-float with a coefficient of lift when moving close to zero, of disk streamlined shape and inlet nozzle of special shaped from below of the housing located just downstream of the outlet nozzle closer to the centre, for water supply on the blades, twisting and direction of the flow along the circle of the channel, while performing a revolution in the direction of rotation of the wheel, and outlet nozzle of special shape designed for release of water in the direction opposite to the motion, for generation of a reactive thrust. To reduce the friction the engine housing is treated by water-repellent agent.
