摘要： A boat propulsor includes a duct, a propeller in the duct and rotatable around a rotation axis extending along an axial direction of the duct, and a rotator to rotate the propeller. An upper portion of the duct includes a plate extending from the duct in the axial direction and including holes. Water streams passing around and along the duct are attenuated as the water streams pass through the holes in the plate.

摘要： A method and device is provided for increasing the efficiency of jet drives by recuperating effective power from the propulsion flow. A ducted propeller in the propeller housing, driven by a driving engine via a drive shaft, conveys the fluid for the jet drive out of the interior Vi of a radial turbine. The fluid is accelerated axially and ejected backwards against the direction of travel. This creates thrust. Because the pressure in the interior of the turbine decreases, new fluid from the environment flows directly via the blades of the rotating radial turbine from the outside to the inside, thereby driving them. A guide apparatus is missing. The power of the radial turbine is transmitted via a transmission to the drive shaft of the propeller, which relieves the driving engine and increases the efficiency of the jet drive. The invention is particularly suitable for electric drives.

摘要： A novel watercraft propulsion device is disclosed that includes multiple propulsive elements improving power and efficiency over prior designs. A self-adjusting variable pitch propeller is combined with a water jet and an exhaust driven turbine to provide optimal thrust and efficiency across the range of engine power, load and watercraft speed. In the preferred embodiment, propulsive elements are axially disposed around a central drive shaft and exhaust port with the combined water jet/exhaust turbine disposed closest to drive shaft and the variable pitch propeller attached to the exterior of the water jet housing. A rotating duct is fixed to the propeller blades and rotates with the blades to reduce cavitation. Combined apparatus provides increased performance and efficiency over all watercraft speeds/load as well as additional safety due to the ducted propeller.

摘要： In a method of providing a dynamic energy-saving superconductive interaction of a rotating propeller with a fluid medium, an optimizer has a modulator modulating a value of a connection by the fluid medium flowing between perforations on working surfaces of a propeller blade through a shunt passage under an action of a difference of pressures generated on the working surfaces by providing a frequency, a range, a law and a phase of the modulating; and the optimizer optimizes a value of at least one parameter of the modulating in dependence on a change of a value of at least one controlled characteristic influencing energy efficiency of a work of an object interacting with the propeller system, thereby providing a dynamic energy optimization of the work of the object by optimization of modulated blowing/suction wave effects on a boundary layer adjacent to the working surfaces of the rotating propeller.

摘要： An air lubrication system of an outer installation type has good efficiency. An air recovering device includes a recovery side chamber provided on a bottom of a ship on a stern side from an air ejecting device which supplies air bubbles to the ship bottom. The recovery side chamber includes air intake holes formed in a portion of the recovery side chamber opposite to the ship bottom through a gap. The air recovering device also includes a recovering section recovering air inside a recovery side chamber. The air bubbles acquired from the air intake holes are accumulated inside the recovery side chamber to generate pushing pressure so that air can be smoothly recovered from the recovering section.

摘要： A marine propeller having multiple adjustable exhaust structures is disclosed. Each adjustable exhaust structure includes an exhaust hole unit with exhaust through holes cut through the outer surface and inner surface of the propeller hub of the marine propeller, an adjustment member with shielding portions mounted in the exhaust hole unit, and a fastening member for locking the adjustment member to the exhaust hole unit. The adjustment member is movable to adjust the shielding area of the shielding portions relative to the exhaust through holes when disengaged from the constraint of the fastening member. Thus, the exhaust volume is adjustable to fit different conditions without changing any component parts of the marine propeller, facilitating ease of use of the marine propeller.
