Abstract
A method for driving ship features that a vacuum or negative pressure region in the front of ship is generated by the water, sucking port, and two water sprayers at both sides, the pressure different between front and rear of ship body can drive the ship forward with reduced resistance, and the sucked water is pressurized and sprayed backward for accelerating the ship. Its equipment is composed of high-pressure water chamber with water sucker, pressurizing power source, sprayer and water outlet.
Description
The present invention relates to a kind of new mode and engine installation that is used to drive the naval vessel.
At present, the engine installation of boats and ships generally all is arranged on quarter, because the power at rear portion can not influence the resistance of fore, ship's speed is big more during the shipping row, and the resistance of fore is just big more, so ship's speed is difficult to too high.
Task of the present invention is: overcome the deficiencies in the prior art, design a kind of can advance as the powered hull of ship and can make fore produce negative pressure (or reduce the fore resistance widely, the hull of operation can not limit the speed of ship because of the resistance of fore), thus the naval vessel driving method and the engine installation of raising ship's speed.
Task of the present invention realizes as follows: the driving method on naval vessel comprises two step: A, is to produce region of no pressure or zone of negative pressure by water sucking mouth on the ship and both sides water injector on the bow, promotes hull by pressure reduction before and after the hull and the method that reduces the fore resistance and advance.B, be being used for method one, being used for producing before a large amount of ship that the water sucking mouth of region of no pressure sucks in water produces between antagonistic force and nozzle and the hull to ejection behind the ship by the purpose made nozzle by the propulsion source pressurization again and produces negative pressure, siphon away the method for fore part current, ship's speed is quickened again.It comprises a high pressure hydroecium that is installed in fore-body the engine installation on naval vessel, and hydroecium has water inlet and nozzle and propulsion source, and the nozzle exocoel has discharge port.
The present invention is because water enters the arrival propulsion source from water inlet, propulsion source becomes the high pressure hydroecium that high pressure water is delivered to engine installation to the water of coming in from water inlet, from the nozzle of high pressure hydroecium, spray again, the antagonistic force that water spray produces promotes hull and advances, therefore when hull moves, not only can advance, and can make fore generation negative pressure or significantly reduce the fore resistance as the powered hull of ship, the hull of operation can not limit the speed of ship because of the resistance of fore, and ship's speed can be very high very high.
Fig. 1 is the straight propelling thrust device of a single-stage of the present invention cutaway view;
Fig. 2 is multistage straight propelling thrust device cutaway view;
Fig. 3 adds propelling thrust device cutaway view for the single-stage drag reduction;
Fig. 4 adds propelling thrust device cutaway view for multistage drag reduction;
Fig. 5 is coaxial multistage major diameter engine installation cutaway view.
A most preferred embodiment of the present invention, as figure, it has a water inlet 1, high pressure hydroecium 2, nozzle 3, propulsion source 4, discharge port 5 high pressure hydroecium 2, water enters the arrival propulsion source from water inlet, propulsion source becomes the high pressure hydroecium 2 that high pressure water is delivered to engine installation to the water of coming in from water inlet, spray from the nozzle of high pressure hydroecium both sides (fore both sides) again after the high pressure water of propulsion source input is constantly imported the high pressure hydroecium, the antagonistic force that water spray produces promotes hull and advances; In order the present invention to be applied to the ship of big displacement, installed the device that reduces the fore resistance additional, as Fig. 3, Fig. 4, shown in Figure 5, the unnecessary water that enters water inlet from fore in the engine installation of big displacement is discharged from fish gill shape discharge port rapidly under the acceleration of this engine installation in-to-in drag reduction nozzle, making it to become the resistance that fore is advanced, and condition has been created in speed-raising in order to navigate.
Claims (6)
1, a kind of naval vessel driving method, it is characterized in that: be to produce region of no pressure or zone of negative pressure by water sucking mouth on the ship and both sides water injector on the bow, promote hull by pressure reduction before and after the hull and minimizing fore resistance and advance, the water pressurization that the water sucking mouth is sucked in simultaneously produces antagonistic force by special nozzle to the afterbody ejection and makes the ship's speed acceleration.
2, a kind of engine installation of ship is characterized in that: it has a high pressure hydroecium, and hydroecium has water inlet, nozzle and propulsion source, and hydroecium has discharge port outward.
3, engine installation as claimed in claim 2 is characterized in that: said propulsion source can be propeller, impeller or the water pump that combustion engine, steam turbine, electrical motor, gas turbine etc. drive.
4, as claim 2,3 described engine installations, it is characterized in that: engine installation can be installed in the front portion of hull, also can be installed in before two lateral deviations of big ship or partially.
5, as claim 2,3 described engine installations, it is characterized in that: during as the direct drive propeller, can omit high pressure hydroecium and nozzle.
6, according to claim 2,3 described engine installations, it is characterized in that: can be installed on the naval vessel by unit, but also two-shipper, multimachine be installed on the naval vessel of different shape, and can promote large ships with a plurality of minitype motivations.
