Description

Jet-propelled rotary engine

Technical field

The present invention relates to a kind of engine, particularly a kind of jet-propelled rotary engine, generally to be applied in the supersonic velocity Push Technology on military and space rocket at present, be applied to a kind of new pattern in rotating machinery field, by the injection of Compressed Gas, expand, accelerator performs to the limit in short Laval nozzle, and the dynamicthrust that this supersonic speed gas jetting is produced all acts on the outer most edge of rotor, therefore there is horsepower large, simple structure, easy to maintenance, power conversion is the characteristic of (100%) fully and completely, can effectively save the energy, reduce and pollute, it is air motor, steam engine, steam turbine, gasoline engine, diesel engine, the renewal product of aero-turbine.

Background technology

The existing machinery that does power with high-pressure fluid, as: air motor, steam engine, steam turbine, the hydraulic turbine, gasoline engine, diesel engine, gas turbine, aero-turbine etc. are all to promote motor rotation with the form of high-pressure fluid impact blade, turbine or piston. According to mechanics general knowledge, this power is commonly called as " impulsion power ". Current machinery is on the market all to utilize impulsion power to come (except the rocket) of work done substantially.

Carry out the machinery of work done with impulsion power, theoretically, its power transfer does not reach 25%, be described as follows as an example of steam turbine example: the turbomachineries such as steam turbine mainly utilize high velocity air to impact blade, more rely on leaf grating turnover air-flow momentum change and obtain thrust, under certain air velocity condition, blade thrust is relevant to rotating speed. The relative speed difference of air-flow and blade is larger, and the thrust obtaining is larger, and speed difference is less, the thrust also less (being directly proportional) obtaining. In the time that the linear velocity of blade reaches jet-impingement speed, speed difference is zero, and the thrust that blade obtains is zero, and power stage is at this moment also zero. Circular is as follows: establish: the steam under uniform temperature certain pressure, by producing supersonic jet after Laval nozzle, we use U_eRepresent. In the time that blade is motionless, the speed difference maximum of air-flow and blade, equals U_e, namely rotor speed is 1 o'clock, the impulsion power maximum that blade bears. But because rotating speed is zero, calculates formula: N=P.F.r/9550 according to mechanical output and calculate [N: power, P: thrust, F: moment=D/2, r: rotating speed=U_e/ (Π D) x60, D: the diameter of rotor (comprising blade)], power stage is also zero. After blade starts to rotate under thrust, along with the increase of leaf line speed, rotating speed is increasing, and along with the speed difference of air-flow and blade is reducing, thrust is also reducing. When the linear velocity of blade reaches U_e/ 2 o'clock, also remaining P/2 only of thrust P, and power stage is at this moment maximum, if N=0.5P*F*0.5r/9550=0.25P.F.r/9550. rotor line speed is greater than or less than U_e/ 2 o'clock, power stage all can reduce. Because impulse air-flow and blade can not reach consistent tangent of direction, the angle of impulsion power input can produce force resolution, so the power transfer of steam turbine is can not reach 25% again. In order to change this situation, designer afterwards allows steam in Laval nozzle, only carry out demiinflation, and then by multistage leaf grating with the blade of degree of reaction, remaining demiinflation steam is carried out to multistage reactionary style expansion acting, so just the power transfer of supercritical turbine has been brought up to 40% left and right.

Proving by the same methods, all machinery with impulse work done, its power transfer can not reach 25%, lets alone and has exceeded. The efficiency that is at present commonly called as on the market gasoline engine is in 35% left and right, and diesel engine is in 40% left and right, and the science that needs is further calculated and checking.

Since ancient times, also the machinery that constantly has people to do work with spray reaction forces in research, as: greatly about century period in Christian era, uncommon sieve sub-in Alexandria has just been invented a kind of " aeolipile " that utilizes the reaction force of steam to carry out work done, this is also steam engine the earliest on the books, is a kind of toy and do not continue research and development but be just used as by people. Steam turbine industry develops into today, this technology is used as to ancient out-of-date technology shields and closes always, causing this machinery that carrys out work done with jet-type counterforce, is out-of-date unwelcome technology professionally trained expert, scholar, doctor in the eyes. In recent years, also there is people to utilize reaction force to carry out the rotating machinery of work done in test, as " rotating power machinery and the system engine " by name of application on November 15th, 1989, the patent that notification number is CN1037192A; The patent that the notification number of application on January 8th, 2004 is US2004/005214A1; " jet engine " by name of application on October 16th, 2007, the patent that the patent No. is 200710045207.0; And " a kind of jet engine " by name of application on August 11st, 2008, patent that the patent No. is 200810150584.5 etc. Regrettably, the invention of these patents, just to carrying out work done with reaction force, imagination has been proposed, as for profit come in this way work done efficiency size and can be energy-conservation? why can be energy-conservation? how could be more energy-conservation? how much energy-conservation? how to calculate all and state. For example: in above-mentioned a few example inventions, although all illustrated that Compressed Gas carries out injection and can produce reaction force, but do not have an example to mention that Compressed Gas sprays rear continuation expansion and accelerates and can produce unique parts---the Laval nozzle of supersonic speed effect, claim convergent-divergent pipe yet.

Know according to the gas dynamical principle of transmitting, give full play to the efficiency of " spraying type rotation motor ", key is to improve its rotating speed as far as possible, because the feature of supersonic velocity Push Technology, to rely on Laval nozzle will there is the gas of certain pressure, " shrinking-expansion " expansion by spray intracanalicular type cross section is accelerated into supersonic speed gas jetting, produces dynamicthrust by the principle of reaction, promotes jet pipe and travels forward. The thrust that this supersonic speed gas jetting produces, only depend on Laval nozzle and import and export gas parameter, and it is irrelevant with jet pipe displacement speed, and this gas jet utilization ratio increases with the increase of jet pipe movement velocity, until movement velocity reaches maximum (being 100% in theory) when consistent with gas efflux velocity. Reach such object, " the High Rotation Speed seal nipple " of this equipment just seems still for important. And current " rotation seal joint " on the market, because being subject to the restriction of technologic material material aspect, the sealing of rubber, maximum line velocity is 15m/s, the maximum line velocity of mechanical seal is 25m/s. Because the axle of " spraying type rotation motor " inlet end is hollow, also to punch and communicate in axle and rotor connection place, safety problem while considering mechanical movement, the design of axle is larger than the diameter dimension of common mechanical axle, like this, rotating speed is high adds that diameter dimension is large, causes at present all on the market rotation seal joints all can not use. And from the figure of above several patents, while mentioning sealing, be exactly briefly to want high pressure sealing to connect by connector in other words, the basic critical problem that does not just show High Rotation Speed sealing, this is also the one of the main reasons that causes the machinery of this project can not come out till now.

Another key issue of spraying type rotation motor, can not to use by multiinjector at grade simultaneously, as the notification number patent that is US2004005214A1, from figure, see, 8 nozzles are enclosed in a cavity, the gas that previous nozzle gushes out, except nozzle is produced a reaction force, also a rear nozzle is produced the thrust of forward, and active force is equal with reaction force fair, so the product of this spline structure can not rotate, we have lived through such failure in actual experiment.

Summary of the invention

Object of the present invention, is to provide a kind of spraying type rotation motor, and the jet-propelled rotary engine that particularly a kind of reaction force of supersonic jet producing while utilizing high-pressure fluid to spray is power, can effectively solve above deficiency. it comprises main shaft (6) is sealed, and don't affect the High Rotation Speed seal nipple (1) of main shaft (6) High Rotation Speed, the buffering friction pair (3) installing additional between mechanical sealing static ring (2) and mechanical sealing linkage ring (4) for reducing sealing friction pair linear velocity, gases at high pressure enter into the main shaft inlet channel (5) of main shaft (6) front end by High Rotation Speed seal nipple (1), be again the interior rotor gas passage (7) of rotor (8) of in-line by profile, Compressed Gas is finally by being assemblied in Laval nozzle (11) ejection on jet pipe pilot hole (9). in the time that the linear velocity of Laval nozzle (11) reaches gas supersonic jet, it is maximum that power transfer reaches. mechanical seal in High Rotation Speed seal nipple (1), has installed N buffering friction pair (3) additional.

In order to solve a difficult problem for high-speed joint, the present invention has innovated two kinds of high-speed joints, and one is labyrinth type without friction high-speed joint, because without friction, so can not produce wearing and tearing, just can produce leakage slightly. A kind of be with buffering friction pair without revealing mechanical sealing high-speed joint. Between original dynamic and static seal friction, install N buffering friction pair additional, like this, can make the rotational line speed between original dynamic and static friction pair, be reduced to 1/ (N+1), lay reliable basis for spraying type rotation motor can normally work long hours.

In order to reduce the pivoting friction resistance of rotor and the resistance that multi nozzle conditions each other, the present invention is yi word pattern by the profile master-plan of rotor (8), and it is streamlined to be water droplet from cross section. Rotor design is become to yi word pattern, only use jet pipe at two ends, effectively pulled open the range ability between jet pipe, the gas jet that can not produce the ejection of previous jet pipe produces negative sense resistance to a rear jet pipe, and the fairshaped rotor profile of water droplet that the rotational resistance of rotor is dropped to is minimum. In order effectively to increase machine power, can design several jet pipe pilot holes (9) at the two ends of rotor (8). Separately, can between jet pipe pilot hole (9) and Laval nozzle (11), install combustion chamber additional, combustible gas is carried out in combustion chamber after burning expansion, spray through Laval nozzle (11) again, to adapt to flammable dynamic power machine as jet-propelled rotation gasoline engine, jet-propelled rotation diesel engine, jet-propelled rotatable gas machine, the use of jet-propelled rotation aero-engine.

When multi nozzle uses, the injection direction of jet pipe will have an angle with the direction of rotation of rotor, like this, except producing the strength of rotation, can also produce axial thrust, be used in the equipment of walking as being fine in aero-engine, just some waste in the time of static starting.
