Description
Affiliated technical field:
Full jet propulsion high speed catamaran is the motion principle scheme of a kind of sea vehicle, adopt the turboaxle motor of aeronautical technology drive the military air compressor of combination (axial flow compressor and centrifugal compressor composition) to behind the supercharging air to the mode of hull bottom inject high pressure gas, reduce the resistance of water, thereby improve the route speed of boats and ships hull.Be a kind ofly all to utilize the high-pressure injection gas propulsive, produce new-type principle of propeller when reducing hull resistance to the propulsive force of hull.
Background technology:
Now, boats and ships that navigate by water on the sea and speedboat adopt the water screw propeller to advance mostly, or after with air cushion hull being hovered, and the mode that advances with air screw again promotes that boats and ships advance.At present, known technology, turboaxle motor, the design manufacturing technology that flows military air compressor, centrifugal military air compressor are ripe, the propulsion of ship principle that I invented, adopted the complete jet-propelled propulsion mode of hull bottom, use the technology of modern turboaxle motor, streaming air compressor, centrifugal compressor, can reduce speed of advance and energy savings that ship resistance improves boats and ships.
Summary of the invention:
The present invention forms according to hydromechanical principle design.We move in two kinds of fluids by designed any boats and ships, a kind of be air, a kind of be seawater.Because the graviational interaction of the earth makes seawater form the sea on earth, the sea freely remains on original position.And our designed boats and ships will be done relative motion in these two kinds of fluids.Therefore hull is under the effect of propeller thrust, and hull and air and the water surface will produce various resistances, hinders ship motion, so; How eliminating and reduce the various resistances of water to hull, is vital to the propulsion mode of boats and ships and the selection and the design of profile.
People always become stream line pattern to the configuration design of the submarine that moves in the aircraft that moves and the ocean deepwater in air.And our design-calculated boats and ships are done relative motion at air between the seawater water surface, and what the various resistances that ship produces when advancing, these resistances had has something in common with aircraft and submarine, and what have is different from aircraft and submarine.This be because aircraft and submarine they be in the mono-medium, to move, (the indication medium is meant air and seawater here) and our boats and ships will move in the demarcation line of two kinds of different media, in the demarcation line of this two media, move, density difference because of this two media, boats and ships are different with the suffered resistance in underwater on when motion water surface, and this is because of the density of water and different the causing of density of air.And the Resistance Distribution that motion the time is produced is quite complicated, because the density of water is 800 times of density of air, so; The resistance overwhelming majority that boats and ships are produced when navigating by water across the sea is from below the sea, and these resistances mainly are made up of friction drag, wave making resistance, eddy resistance etc. with verified through the research of modern fluid mechanics.The speed best bet that wants to improve boats and ships is how to reduce water these several resistances to boats and ships.Certainly; These factors have determined me in the thinking that designs the novel ship principle of propeller, and I think that we can utilize the air of occurring in nature, help our boats and ships and reduce water resistance? though this idea has had for a long time, as: air cushion vehicle, aerofoil boat etc.; But I have one to be different from air cushion vehicle, the idea of aerofoil boat, I think that we can directly be pressed into air the bottom of hull with high-pressure compressor, / 3rd places of disembark head open several air nozzles alow, when hull bottom inject high pressure gas makes hull reduce resistance, again hull is produced propulsive force, thereby improves the speed of boats and ships? I think that answer is sure.
Technical scheme:
According to this imagination, I have drawn one, and to utilize ship that high pressure air advances and it be work principle conceptual design figure how, and I am called it (full jet propulsion high speed catamaran).Shown in (accompanying drawing-1); From accompanying drawing as can be seen, this is the catamaran of an airflow design, there are two air inlets in the place ahead on the middle part of ship, air enters through two midship air inlets, at two turboaxle motors after reducing gear is slowed down, after driving two compound type air compressors (axial flow compressor and centrifugal compressor are formed) supercharging, the high pressure gas that produce, flow through gas collection cabin in the hull, two high pressure gas pipelines along hull are carried to stem, high pressure draft directly enters pressure cabin and has carried out having changeed after the supercharging the curved of 270 degree behind aqueous vapor sealed hydraulic globe valve, goes to the hull bottom spray through the air nozzle of hull bottom.When being produced propulsive force, hull also hull has been produced one deck air cushion, this layer air cushion separates the part of hull and seawater, thereby reach the effect that reduces the hull frictional resistance, when air flows alow owing to be subjected to the pressure of seawater, gas flow process alow is a very complicated motion process, we know because the proportion of air is very little, just high pressure gas are sprayed toward hull bottom if we are careless several mouths of opening alow, and that is not all right.Because air specific weight is little, when air when air nozzle sprays to hull bottom, air disorderly steams on can be along smooth hull toward the water surface under the hull of slyness everywhere, like this with regard to the purpose of out of reach minimizing hull resistance.The propulsive force of hull is increased in order to reach when reducing hull resistance to some extent, so hull design has been become to have a plurality of hulls of groove, these fall groove is exactly the bleed groove of high pressure air, hull has had the bleed groove, at this moment high pressure air will be controlled under the hull bottom, form one deck air cushion alow, and hull bottom is constantly replenished down by gas, hull bottom is just separated by air cushion, and seawater has just reduced the friction drag of hull like this.
To be hull and seawater produce when ship motion difference of pressure and seawater form the friction force of hull the eddy resistance of hull afterbody.Now because the high-revolving stern that flows to of gas of hull bottom will be replenished the stern hull pressure that institute's seawater that arranges reduces in high-speed motion, the eddy resistance of hull is with regard to natural disappearance like this, thereby reduced the eddy resistance of hull.
For wave making resistance, because its formation is by the shape decision of hull, so we will be in the pond when the choosing of hull more does experiment and choose the little ship type of wave making resistance to the greatest extent.Because the existence of wave making resistance, make the raising that the speed of the naval vessel speed of a ship or plane is difficult to, be hull bottom jet propulsion principle here because full jet propulsion high speed catamaran adopts, boats and ships are when advancing, because hull bottom has one deck air-sprung to exist, hull is under the combined action of air-cushion force and these two bursts of strength of hydrodynamic lift, and hull is lifted from the water surface, area that hull is soaked and shape reduce, and wave making resistance has also and then reduced.For boats and ships fall back principle just as can be known from Figure of description, just be not added on explanation at this.
Why do I select the arrangement of catamaran for use when this principle of propeller of design, and do not use the arrangement of single hull? this is to consider from the stability of hull when the water surface moves.Because this ship hull bottom has the existence of high pressure gas, if we are designed to single hull with ship, because gas flow process alow is a very complicated motion process, gas can make the each several part pressure of single hull hull bottom unbalanced, this will destroy the stability that boats and ships navigate by water across the sea, in any case stability when catamaran navigates by water across the sea is all good than single hull therefore.Holding is not the preceence that just can show it with jet propelled boats and ships, so I have selected catamaran.
