Description
The present invention relates to a kind of centrifugal engine, belong to the dynamic power machine field, particularly belong to engine art.
With the open-cycle engine of air as oxygenant and working medium, be one of most important type of motor, common internal-combustion engine, gas turbine, air breathing engine all belong to this type.The common feature of this class motor is that its work cycle all comprises air compression, air and fuel mix burning, three processes of combustion gas expansion working, Just because of this, different motors can constitute new work engine mutually, as turbocharged internal combustion engine, free-piston-turbine combined engine, turboaxle motor, turbojet engine etc.In this class composite engine, finish the burning of air compression, air and fuel mix, produce the high pressure-temperature combustion gas but not externally the mechanism of output power be called gasifier section or gas generator; Be responsible for the interior mechanism that can be converted into mechanical energy and external output power of the high pressure-temperature combustion gas of prime gasifier section generation is called combustion gas energy conversion device or power output device.With regard to the complexity of the difficulty that realizes function and structure, gas generator wants specific power output unit difficulty complicated many, because only compare with regard to transfer power, pressurized air institute consumed power is often greater than motor institute output power, gas generator also will be finished multiple functions such as air compression, oil inflame simultaneously, and gas generator is the core institution of composite engine thus.A kind of gas generator often can be combined into multiple motor, for example based on the turbo type gas generator multiple aeroengines such as whirlpool axle, vortex, turbofan, whirlpool spray is arranged.This shows the development new work engine is had very important meaning if can provide a kind of novel gas generating means of superior performance.
The present invention provides a kind of centrifugal gasifier section, and has provided this centrifugal gasifier section with the multiple centrifugal engine of multi-form combustion gas energy conversion device in conjunction with formation.Centrifugal gasifier section core component is a centrifugal rotor, it by centrifugal air compression impeller, rotate the firing chamber, radial-flow turbine is coaxial successively is formed by stacking, the principle that it utilizes the gas of different temperatures can produce different pressure under identical effect of centrifugal force is carried out work and is produced the high pressure-temperature combustion gas.Centrifugal gasifier section is compared with the piston type fuel gas generating means, has specific power height, advantage that exhaust emission is little; Compare with the turbo type gasifier section, have the advantage that the throughput regulation range is wide, be not subjected to the restriction of water spinach plug phenomenon.
Whole centrifugal engine is made of several sections such as body (1), centrifugal gasifier section (2), combustion gas energy conversion device (3) and some assisting agencies.
The function of body (1) is that each parts to centrifugal engine provide suitable mounting point, and makes their common centrifugal engines of forming a coordinating and unifying.
The function of centrifugal gasifier section (2) is to produce the high pressure-temperature combustion gas.Centrifugal gasifier section (2) is made of centrifugal rotor (4), rotor cavity (5), (6) three parts of rotor drive.
The profile of centrifugal rotor (4) is a solid of rotation, and it is by suction port (7), centrifugal air compression impeller (8), rotation firing chamber (9), radial-flow turbine (10), (11) five coaxial successively being formed by stacking of parts in air outlet.The profile of rotating firing chamber (9) is a cylindrical body, and the week symmetry is provided with and a plurality ofly is flame tube (16) circular or the fan annular with shaft parallel, cross section in cylinder.The structure of centrifugal air compression impeller (8) and radial-flow turbine (10) is symmetry substantially, and they all have the blade with flame tube numbers such as (16), thereby gas circuit separately is separated into the air pipe that number equates with flame tube (16).Air pipe (17) outlet of centrifugal air compression impeller (8) is connected with flame tube (16) inlet that rotates firing chamber (9), and flame tube (16) outlet of rotating firing chamber (9) is connected with air pipe (19) inlet of radial-flow turbine (10); The center three of the center of centrifugal air compression impeller (8) air pipe (17) outlet, the center of rotating firing chamber (9) flame tube (16) and radial-flow turbine (10) air pipe (19) inlet equates that to the distance of rotor axis this distance is called the effective radius of centrifugal rotor (4).For fear of when starting gas reflux, the radius of centrifugal rotor (4) suction port (7) should be slightly less than the radius of air outlet (11), but the two is all much smaller than the effective radius of centrifugal rotor (4).
During engine running, air enters rotor from suction port (7), air is compressed and quickens in centrifugal compression impeller (8), air and fuel oil generation combustion reaction in firing chamber (9), fuel gas temperature raises and isobaric expansion, combustion gas puffing and deceleration in radial-flow turbine (10), last combustion gas be (11) outflow rotor from the air outlet.Because the effective radius of centrifugal compression impeller (8) and radial-flow turbine (10) equates, and the radius difference of the suction port (7) of centrifugal rotor (4) and air outlet (11) is less, and compression impeller (8) equals combustion gas to radial-flow turbine (10) institute work substantially to air institute work; Again because the temperature of combustion gas in radial-flow turbine (10) is higher than the temperature of air in the compression impeller (8), thereby the density of the interior combustion gas of radial-flow turbine (10) is less than the density of the interior air of compression impeller (8), the numerical value that the numerical value that gaseous-pressure reduces in the radial-flow turbine under identical action of centrifugal force (10) increases less than compression impeller (8) inner air pressure, thus the pressure that causes air outlet (11) to locate combustion gas is located the pressure of air greater than suction port (7).
The fundamental characteristics of centrifugal rotor (4) be when it turns round except overcoming surface friction drag consumed energy hardly, it can produce high-pressure gas simultaneously.Another important feature of centrifugal rotor (4) is that its firing chamber (9) is fixed in the same rotating shaft with compression impeller (8), radial-flow turbine (10) and rotation together, air-flow mobile between compression impeller (8) and firing chamber (9), between firing chamber (9) and the radial-flow turbine (10) is to carry out in relative static pipeline like this, and gas is less with respect to the tube wall flowing velocity, therefore there is not complicated speed coupled relation, this structure not only helps improving engine efficiency, and allows free adjustment gas flow in the scope of broad.Just because of this point, centrifugal gasifier section (2) can constitute multi-form centrifugal engine with combustion gas energy conversion device (3) coupling of various ways, and these motors can be regulated power, rotating speed and torque in the scope of broad.
The fuel cut mode of centrifugal rotor (4) has two kinds: a kind of is the direct spray type fuel feeding, promptly fuel oil is directly sprayed into firing chamber (9), this mode need be provided with one by oil inlet hole (12), centrifugal fuel pressurization pipe (13) and oil injecting nozzle (14) three parts formation rotor oil circuit; Oil inlet hole (12) is located in the axle center of centrifugal rotor (4), and is connected with outer fuel supply line by rotary seal; Centrifugal fuel pressurization pipe (13) is arranged in the centrifugal rotor (4), and it is communicated with oil inlet hole (12) and oil injecting nozzle (14); The opening of oil injecting nozzle (14) is positioned at the ingress of firing chamber (9); Another kind is premixed fuel feeding, and promptly fuel oil is vaporized earlier and located and air mixing at suction port (7), and mixed inflammable gas enters firing chamber (9) from suction port (7) through centrifugal compression impeller (8), and this mode does not need to be provided with the rotor oil circuit again.
Centrifugal rotor (4) is installed in the rotor cavity (5), and rotor cavity (5) is located and air outlet (11) locate to be provided with rotary seal at rotor suction port (7), thereby the low-pressure cavity that hyperbaric chamber that air outlet (11) are located and suction port (7) are located is kept apart.
Rotor drive (6) be generally one with the coaxial turbine mechanism of centrifugal rotor (4), the high pressure-temperature gas driven centrifugal rotor (4) that it utilizes centrifugal rotor (4) to produce rotates.In some cases, combustion gas energy conversion device (3) can directly drive centrifugal rotor (4) and rotate, and does not at this moment need to be provided with special-purpose rotor drive again.Between rotor drive (6) and centrifugal rotor (4) rotating shaft the ratchet of handy one-way rotation be connected, rotor drive (6) can drive centrifugal rotor (4) rotation when normal working of engine like this, and centrifugal rotor when engine start (4) is driven by starter motor but rotor drive (6) does not rotate.Having under the situation of power supply, rotor drive (6) can also be a motor, so do not need to establish special-purpose starter motor again, and the starting of rotor, shutdown, acceleration, deceleration is very convenient.
The function of combustion gas energy conversion device (3) is that the heat energy of the high pressure-temperature combustion gas of centrifugal gasifier section (2) generation is converted into mechanical energy and external output power.The combustion gas energy conversion device (3) of centrifugal engine can have multiple scheme, and first kind of scheme is that combustion gas energy conversion device (3) is a turbine mechanism, and it combines with centrifugal gasifier section (2), can constitute the turbo type centrifugal engine.Second kind of scheme is that combustion gas energy conversion device (3) is a piston mechanism, and it combines with centrifugal gasifier section (2), can constitute the piston type centrifugal engine.The third scheme is that combustion gas energy conversion device (3) is one can produce the injection pipe mechanism of thrust, and it combines with centrifugal gasifier section (2), can constitute jet-propelled centrifugal engine.The 4th kind of scheme is that a centrifugal gasifier section (2) while and a plurality of combustion gas energy conversion device (3) are exported centrifugal engine in conjunction with constituting multiterminal.The 5th kind of scheme is that centrifugal gasifier section (2) while and a combustion gas energy conversion device (3) combination that a plurality of delivery pressures equate constitutes high-power centrifugal engine.
Centrifugal engine can also be provided with a prime air compression plant (15) at the front end of centrifugal rotor suction port (7), it is generally an axial-flow blower or a centrifugal impeller, it can be driven by rotor drive (6) with centrifugal rotor (4) is coaxial, also can be driven by combustion gas energy conversion device (3).Prime air compression plant (15) be provided with efficient and the specific power that helps improve centrifugal engine.When the pressure of prime air compression plant (15) than much smaller than the pressure of centrifugal rotor (4) air compression impeller (8) than the time, the performance of centrifugal engine is little with the situation difference that prime air compression plant (15) is not set; When the pressure of prime air compression plant (15) than greater than the pressure of centrifugal rotor (4) air compression impeller (8) than the time, the performance of centrifugal engine will more approach common turbogenerator.
The assisting agency of centrifugal engine comprises Fuel System, combustion gas system, starting system, lubricating system, cooling system etc., realize functions such as the supplying fuel, combustion gas configuration, ignition start of centrifugal engine, lubricated cooling by them respectively, and carry out various regulating and controlling and instruct.
The Fuel System of centrifugal engine is made of several parts such as fuel tank, oil pipe and delivery rate control gear, and the delivery rate control gear can be that the instruction of sending provides best delivery rate according to load state, engine running condition shape and people.The basic control mode of centrifugal engine fuel oil speed is that the maintenance fuel air ratio is a constant when normal working of engine, thereby makes the temperature of firing chamber keep constant, can increase fuel air ratio when motor quickens, and can reduce fuel air ratio when engine retard.
The combustion gas system of centrifugal engine comprises that parts such as air-strainer, sucking pipe, outlet pipe and gas path control valve door, its effect are the assisted gas circulations, regulation and control combustion gas configuration.
The starting system of centrifugal engine comprises starter motor and two parts of starting ignition device.The effect of starter motor is can provide an initial velocity to centrifugal rotor when starting.The effect of starting ignition device is to carry out initial ignition to the firing chamber when starting, and it is made of starting circuit and the spark plug that is positioned at the firing chamber.When normal working of engine, starting system quits work.
During the centrifugal engine running, the gas circuit that air enters centrifugal rotor (4) from rotor suction port (7), through adiabatic compression, isobaric intensification, adiabatic expansion, flow out from rotor air outlet (11), enter the gas circuit of combustion gas energy conversion device (3) then again, motor is discharged in further adiabatic expansion acting at last again.
Being located at the air that centrifugal rotor suction port (7) locates is room temperature state, and its temperature, pressure, density, maximum jet velocity are respectively T

The rotation speed n that last formula provides is the rotating speed of turbine (3) when most effective, and its numerical value is fully by the working state decision of centrifugal rotor (4); The torque of turbine (3) is proportional to spray chews section area S, sprays torque and the power that the size of chewing section area S can be regulated motor by regulating.
For the piston type centrifugal engine, the air displacement of establishing piston is L, and then its rotation speed n and torque M can be expressed as:
The n-freedom is adjustable

0 2/4π
By last formula as can be seen, by the working state decision of centrifugal rotor (4), rotating speed can be regulated arbitrarily fully in the torque of piston type centrifugal engine, the rapid-result direct ratio of power transfer.
For jet-propelled centrifugal engine, establishing injection pipe (3) discharge area is S, and then gas blowing speed U and jet thrust F can be expressed as:
U＝[αβ/(1+α)]
1/2W
0
F＝[αβ/(1+α+β)]Sρ

By last formula as can be known, by the decision of the working state of centrifugal rotor (4), jet thrust F is proportional to injection pipe (3) discharge area S to jet velocity fully, the size that can regulate thrust F by the size of regulating injection pipe (3) discharge area S.
Because centrifugal engine has the advantage that specific power is big, efficient is high, exhaust emission is few, power regulating range is wide, and has multiple power output form, thereby has broad application prospects in fields such as automobile, aviation, boats and ships.The technological difficulties of centrifugal engine are that the requirement material therefor has high specific strength and higher heat resistance, but development along with modern new material technology, particularly high-performance composite materials and high performance ceramic material technology is ripe gradually, and these technological difficulties of centrifugal engine will be readily solved.
