Description
One, technical field:
The present invention relates to a kind of pulse-knocking engine and operation method, particularly a kind of have pinking to change the multi-pipe impulse detonation combustor of penetrating the device connection.
Two, background technique:
Detonation wave can be propagated to burning mixt not with the speed of several kms of per second, and combustion process thereafter can be considered the isochoric combustion process, has high combustion efficiency.Can think to produce stable thrust when the pulse-knocking engine frequency of okperation reaches higher, fitness for purpose reaches more than 100 hertz.The frequency of okperation that how to improve pulse-knocking engine is the direction of research institution's effort.Pulse-knocking engine technology (PDET) plan that US National Aeronautics and Space Administration is implementing is also referred to as the plan of innovation aviation aircraft, is in the starting stage at present.
No matter be rocket type pulse-knocking engine or air-breathing pulse detonation engine, all be bipropellant propulsion system basically.For air-breathing pulse detonation engine, the overwhelming majority that air occupies combustion chamber volume is main propellant agent, and gaseous fuel or liquid fuel relative volume are less to be secondary propellant; Usually adopt systems such as liquid oxygen/gas hydrogen, oxygen/kerosene for the rocket type pulse-knocking engine, no matter adopt which kind of system all to have the bigger situation of a kind of propellant agent volume ratio, we are referred to as main propellant agent, another is called secondary propellant, and the Gaseous Hydrogen in liquid oxygen/gas hydrogen, the oxygen in oxygen/kerosene are main propellant agent and mostly are gaseous state.
Existing pulse-knocking engine roughly can be divided into two classes:
First kind is exactly the pulse-knocking engine with classical cyclic process, one end opening, the mixture of the other end spray fuel at intermittence and oxygenant, ignition and detonation then, detonation wave spreads out of detonation chamber, because burnt gas still has very high temperature in the last circulation, therefore must fill and to fill the separation gas of suitable volume before the quick-fried mixture, otherwise have premature firing and continuous burning problem.The pulse-knocking engine of this mode also needs an ignition and detonation device in addition, and since each circulation all to light a fire, during high-frequency work electric power requirement very big, exceedance kilowatt.When the detonation chamber internal diameter is very big, even if use the high energy electric ignition system, also be difficult to form fast detonation wave, must use detonate tube.Detonate tube itself is exactly the complicated pulse detonation rocket engines system of a cover, and it be unable to do without electric ignition system and independent isolating gas system too and therefore uses the pulse-knocking engine of detonate tube complicated more.
Second kind is people's such as Russian V.A.Levin resonant cavity pulse detonation system, fuel and partial oxidation agent enter and enter resonant cavity through superonic flow nozzzle after precombustion chamber is discharged rich combustion high-temperature gas and other oxygenant is mixed by isobaric combustion, form so-called high frequency pinking, it is actually a kind of mixing burner, up to the present still fails to form real knocking combustion.In sum, existing pulse-knocking engine or seriously rely on powerful ignition and detonation device and independently isolate the gas system; Can't form full-blown detonation wave.Exist some that problem to be solved is arranged in addition: 1, pinking detonate, the accurate control of maintenance and pinking process, 2, atomizing, injection, the blending of liquid fuel and oxygenant, 3, low excessively, the unstable properties of pulse-knocking engine firing chamber initial pressure.If these problems can not effectively solve, will seriously hinder the raising of detonation frequency and have a strong impact on the extensive use and the development of pulse-knocking engine.

Behind the stable operation any cover pinking unit all must utilize it change by pinking knocking combustion produces in the detonation chamber of penetrating other pinking unit that device is connected energy and material change by pinking penetrate that the propellant agent that the instantaneous pressure of device finishes himself recharges, the whole process (for example in 0.5～2ms) of blending and direct initiation, this process circulates between each cover pinking unit and hockets repeatedly in this group, continuously alternately produce the pulse-knocking burning, have the knocking combustion product to discharge at a high speed and produce thrust from the detonation chamber outlet.Described knocking combustion product comprises the energy and the material of the form of ownership that knocking combustion produces.Change by these pinkings and to penetrate between the different pinkings unit that device is connected alternately " detonate tube " each other, alternately force each other to recharge, " power source " of blending and the whole process of detonating.
Each above-mentioned pinking is changeed to penetrate all has the pinking commentaries on classics of expanding to penetrate the device inner chamber in the device, can hold a cover pinking unit in it and finish the required same class propellant agent of a knocking combustion, pinking is changeed and to be penetrated the device inner chamber and only change all connecting tube of penetrating device by this pinking and be positioned at this pinking and change all propellant agents inlets of penetrating device and communicate with the external world, and remaining part changes the pinking commentaries on classics of penetrating device by this pinking and penetrates the device shell seal; The inner chamber that all connecting tube of penetrating device are changeed in each pinking all changes the pinking commentaries on classics of penetrating device with this pinking and penetrates the device intracavity inter-connection and become the part that the device inner chamber is penetrated in this pinking commentaries on classics; Having opening only to change the pinking of penetrating device with this pinking respectively each connecting tube changes the pinking unit intracavity inter-connection of penetrating a device inner chamber and a pinking unit, and the internal diameter of connecting tube is much smaller than pinking unit inner chamber; Described each pinking is changeed and is penetrated that the pinking unit inner chambers of device by the every cover pinking unit in its at least two connecting tube and at least two cover pinking unit are connected respectively and penetrate the pinking unit intracavity inter-connection that the device inner chamber will at least two cover pinking unit through changeing with the pinking that all is connected these connecting tube, is changeed by at least one pinking like this and penetrates device and be interconnected and become one group by will two overlapping the pinking unit at least its two connecting tube at least.The structure that can also constitute two-way ejector action in the device inner chamber is penetrated in connecting tube and pinking commentaries on classics, alternately utilize pinking unit inner chamber to enter the high energy knocking combustion product high-speed jet of each connecting tube as the injection air-flow by the pinking unit that produces knocking combustion, each pinking commentaries on classics is penetrated the device inner chamber as mixing chamber, make and constantly enter pinking by propellant agent inlet and change the propellant agent of penetrating in the device (gaseous state) and become by the injection air-flow, can be easy to make propellant agent to be inhaled into pinking by the external world through the propellant agent inlet by injection principle changes to penetrate to be pushed in the device to be changeed by this pinking again and penetrates each cover that device is communicated with not in the pinking unit inner chamber of pinking unit, replaces matter and energy that two-way injection utilizes knocking combustion to produce and has improved by what the pinking unit inner chamber propellant agent that respectively overlaps the pinking unit of penetrating this group that device is communicated with was changeed in this pinking and recharge efficient (referring to accompanying drawing 1.1.2-1.1.5).
In above-mentioned each when starting multi-pipe impulse detonation combustor of the present invention, in the detonation chamber of at least one cover pinking unit in this group the ignition and detonation device is installed, described ignition and detonation device is ignited in the detonation chamber of this cover pinking unit at its place and is just closed after the quick-fried mixture that just begins causes at least once initial knocking combustion; After this knocking combustion product changes by pinking back and forth and penetrates device and alternately propellant agent, energy, pressure, high temperature have been fired waste gas and pass to be changeed by this pinking and penetrate each pinking units alternately direct initiation that device is communicated with, and can not only substitute the effect of ignition and detonation device fully and can also play the effect of knocking combustion stabilizer in this group.
The propellant agent inlet that above-mentioned middle pinking commentaries on classics is penetrated in the device can guarantee that the propellant agent of capacity enters the pinking commentaries on classics by the propellant agent inlet and penetrates in the device inner chamber, its middle pressure that sprays the filling propellant agent changes the middle pressure of penetrating in the device inner chamber greater than pinking, the propellant agent ingress also can have one-way valve or pneumatic valve etc. to prevent backflow device, and it can unidirectionally be closed and prevent tempering.
When propellant agent was the propellant agent of gaseous state kind, pinking was changeed all propellant agents inlets of penetrating in the device and is changeed to pinking and penetrate the propellant agent that sprays the similar gaseous state kind of filling in the device inner chamber (for example main propellant agent is an air in above-mentioned; Secondary propellant is gaseous ethylene, acetylene etc.)。Change when penetrating device and being used to spray the secondary propellant of the liquid kind of filling as pinking, each start described a kind of have pinking change penetrate the multi-pipe impulse detonation combustor of device during, all propellant agents inlets of penetrating in the device are changeed in this pinking that is used for spraying the secondary propellant of the liquid kind of filling, there is at least one propellant agent inlet to change to penetrate and sprays the secondary propellant that is filled with capacity gaseous state kind secondary propellant composition in the device inner chamber as starting propellant agent (gaseous ethylene for example to pinking, acetylene etc. or gaseous ethylene, the mixture of liquid fuel of acetylene etc. and atomizing), like this can emptying this pinking change to penetrate the air in the device and enter easily and form the quick-fried mixture that just begins in the detonation chamber, and remaining propellant agent inlet sprays the secondary propellant (gasoline for example of the liquid kind of filling atomizing, kerosene, JP10 etc.); Start the secondary propellant finish the liquid kind of only spraying the filling atomizing after the smooth working and stop to spray the startup propellant agent of filling gaseous state kind, even use the secondary propellant of liquid kind like this, pinking is changeed and to be penetrated in the device inner chamber the also mixture of the secondary propellant of the liquid kind of the startup propellant agent of of a sort abrim gaseous state kind and atomizing, this mixture still is not can quick-fried mixture can not change penetrate in the device inner chamber in pinking to burn, and the propellant agent of gaseous state kind becomes the carrier (for example gasoline of gaseous ethylene and atomizing) of secondary propellant of the liquid kind of atomizing; Starting detonates finish with the motor smooth working after only spray the secondary propellant of the liquid kind of filling atomizing, pinking this moment changes that to penetrate temperature in the device inner chamber high and have High Temperature High Pressure that part knocking combustion product jet the enters formation waste gas that fires at a high speed fully can be with the rapid carburation by evaporation of secondary propellant of the liquid kind of atomizing, what the part high temperature penetrate in the device inner chamber was changeed in pinking fires the carrier that waste gas becomes the secondary propellant of the liquid kind of having vaporized, solved the difficult problem of the atomizing even the vaporization of liquid fuel, but still not can quick-fried mixture can not change to penetrate to produce knocking combustion in the device inner chamber and (for example fired waste gas and gasoline in pinking, the kerosene steam mixture), otherwise pinking change penetrate may occur in the device inner chamber can quick-fried mixture the (gasoline of air and atomizing or vaporization for example, the mixture of kerosene).When the whole main propellant agent (for example air) that device only is used to spray filling gaseous state kind is penetrated in the pinking commentaries on classics, and all secondary propellants do not change when not penetrating device and spraying filling by pinking, the propellant agent inlet (not drawing in the accompanying drawing) that other is arranged in detonation chamber of described every cover pinking unit, these propellant agent inlets can spray whole (for example Wu Hua the gasoline) of the liquid secondary propellant of appropriate gaseous state of measuring or atomizing on appropriate opportunity in these detonation chambers.
Use gaseous state or liquid secondary propellant to finish as starting propellant agent that starting detonates and make also can use instead by solid propellant after the motor smooth working for example sprays into the propellant agent inlet by Solid Fuel-Rich Propellant (fuel that the solid ducted rocket propulsion system uses) the rich combustion gas body that partial combustion produced in rich combustion gas body generator (not shown) as secondary propellant in above-mentioned, i.e. the present invention under certain condition can also use solid fuel indirectly.
Also need to prove in above-mentioned: being positioned at pinking changes and to penetrate device and change the independent or shared intake duct of penetrating the upstream that the propellant agent inlet that sprays the main propellant agent of filling in the device inner chamber and detonation chamber enter the mouth to pinking, for air-breathing pulse detonation engine, its propellant agent inlet and intake duct be connected with various Air pressurizers (not drawing in the accompanying drawing); For the rocket type pulse-knocking engine, the upstream of all propellant agents inlet can only be connected (not drawing in the accompanying drawing) such as the controlled supply pipeline of flow of one of secondary propellant or main propellant agent two classes and air cylinders.Intake duct and propellant agent ingress can also prevent backflow device, and as one-way valve or pneumatic valve etc., it can under high pressure unidirectionally be closed; The detonation chamber outlet can connect independent or shared various forms of jet pipes (not drawing in the accompanying drawing).
The invention has the beneficial effects as follows: special construction of the present invention has determined all pinking to change to penetrate device and can annotate in advance, storage, transfer, atomizing even vaporization liquid propellant, same class propellant agent in it is can not produce knocking combustion by quick-fried mixture, pinking is changeed and to be penetrated device and high energy knocking combustion product was changeed from pinking through connecting tube penetrate the device inner chamber and come in and go out back and forth behind the stable operation, utilize energy that knocking combustion produces and material instantaneous (for example in 0.5～2ms) to force to finish other not recharging of the propellant agent in the pinking unit, the whole process of blending and direct initiation, and except that this process, can not form (except the quick-fried mixture formation stage that just begins) by quick-fried mixture in the detonation chamber, avoid the preignition and the continuous burning problem of ignition mixture, therefore do not needed to isolate the gas system; By in the instantaneous direct initiation detonation chamber of high energy knocking combustion product jet that follows up subsequently can quick-fried mixture, change by pinking and to penetrate between the different pinkings unit that device is connected " detonate tube " each other, do not rely on powerful ignition and detonation device, can not only substitute the effect of ignition and detonation device behind the stable operation fully and can also in this group, play the effect of knocking combustion stabilizer; High energy knocking combustion product has solved the low excessively problem of initial pressure in the detonation chamber to the compression of propellant agent; The alternate cycles of this process has solved the accurate control of knocking combustion in this group and the problem of maintenance, stable performance, the cycle efficiency of pulse-knocking engine work are improved, all penetrated the instantaneous frequency of okperation that has significantly improved every cover pinking unit in this group of finishing of device pressure shortening by the pinking commentaries on classics owing to form each condition, the link of knocking combustion, single tube can reach hundreds of hertz.Pinking in this group
