Description
Technical field
The present invention relates to aviation power propulsion system field, relate in particular to a kind of flameholder on duty.
Background technology
Flameholder is the core component of aeroengine thrust augmentation combustion chamber and scramjet combustor, and its structure and layout have determined ignition quality and the flame holding and the efficiency of combustion of combustion chamber.Improve the combustibility of stabilizer, improve the performance of after-burner exactly, thereby improve the overall performance of engine.Development with modern aeroengine after-burner technology is had higher requirement to flameholder.Particularly low in combustion chamber inlet air flow temperature, pressure is low, under the fast situation, the igniting reliability variation of existing flameholder, stable operation range narrow down, efficiency of combustion is not high, therefore, need the novel flameholder on duty of development.
The aero-engine of band after-burner mainly contains turbojet engine and fanjet, and bullet mainly is a punching engine with engine, and punching engine burning organisation and aeroengine thrust augmentation combustion chamber are basic identical.But because the parameter of engine and performance is different, the flameholder pattern of use is also just different.
The characteristics of turbojet engine after-burner tissue burning; Be the high 1000-1200K of inlet air flow temperature, evaporativity can reach more than 80% fuel oil in flameholder the place ahead, and the tissue burning easily; Afterburner ignition and the conversion of fuel feeding subregion can not influence the stability of compressor work; To complete afterburning oil-gas ratio excursion little (0.026-0.055), do not require soft ignition from little reinforcing, do not use flameholder on duty just can satisfy the engine performance requirement.Therefore, choice structure is simple, in light weight, the flameholder of good manufacturability stressing, and generally adopts the V-flame stabilizer.
There are two strands of air-flows of intension and outer culvert in the characteristics of fanjet after-burner tissue burning, and the intension gas flow temperature is high, and it is low to contain gas flow temperature outward, and the temperature difference is bigger.Overall inlet temperature is low, and fuel oil has only about 5% in the evaporativity in flameholder the place ahead, organizes difficulty of ratio of combustion, and stability problems is outstanding, improves efficiency of combustion and has any problem, and be easy to generate hugging.Can forward to fan because the pressure that produces during afterburner ignition is exsule;, reinforcing causes the fan surge when connecting; Requirement is wide from little reinforcing to complete afterburning oil-gas ratio excursion, and (the igniting oil-gas ratio is generally 0.002; Complete afterburning oil-gas ratio can reach 0.068), thus the soft ignition measure must be taked, usually at the annular flameholder on duty of indoor layout one circle of afterbunring.
Punching engine is not owing to have compressor and turbine; Have only air intake duct, combustion chamber, jet pipe; Make inlet air flow speed height, pressure low (low pressure can reach 0.05Mpa), the temperature low (500-800K) of combustion chamber, thereby cause ignition difficulties, flame holding and efficiency of combustion to reduce.Therefore, flameholder on duty be need adopt,, efficiency of combustion and engine performance improved to improve ignition performance and flame holding at scramjet combustor.
Several kinds of stabilizers below main use the in aero-engine and punching engine evolution:
The v-shaped flame stabilizer is as shown in Figure 1, is two-dimentional trench structure, and the drift angle of stabilizer is between 30-60 °.It is the most widely used stabilizer of after-burner, has flame holding and simple structure preferably.Major defect is that working range is narrow, and the igniting oil-gas ratio is high, poor stability under the low-temp low-pressure.And in fanjet,, when fuel-oil atmozation is bad, be prone to the low-frequency oscillation burning when outer culvert temperature is low.
Two v-shaped flame stabilizers are as shown in Figure 2, and it is made up of opening V-arrangement stabilizer S 13 and a little V-arrangement stabilizer S11, forms continuous slit S12 between the two.Can make the coefficient decreased 25-30% that suffers a loss with conventional v-shaped flame stabilizer contrast, improve ignition quality and efficiency of combustion, improve the fuel-lean blowout performance, but can not satisfy the requirement of flame holding under soft ignition and the low pressure.
Thin film evaporation v-shaped flame stabilizer structure is as shown in Figure 3; It is made up of interior v-shaped flame stabilizer S34 and outer v-shaped flame stabilizer S33, air inlet ring (or air inlet pipe) S32 and oil spout bar S31 etc., forms the slit between interior v-shaped flame stabilizer S34 and the outer v-shaped flame stabilizer S33.Local fuel oil is gone up aperture through oil spout bar S31 and is sprayed in the air inlet ring (or pipe) and the air blending, on the stabilizer wall, forms oil film.Formed gas mixture is discharged from the gap of stabilizer trailing edge, gets into the recirculating zone.Because local fuel feeding can be controlled, thereby has good ignition performance and flame holding, but the conventional v-shaped flame stabilizer of pitot loss coefficient ratio is bigger.
The suction-type flameholder is as shown in Figure 4.It is on two sidewalls of common v-stabilizer, leaves some custom-designed air inlets, and the gas stream that lets the place ahead is told a part and got in advance in the lee side and recirculating zone of stabilizer.This stabilizer has simplicity of design and the good characteristics of combustibility, and combustion stability limit is widened, and oil-poor state down-firing is easy.
Britain's this shellfish flameholder on duty is as shown in Figure 5, and its operation principle is that additional fuel oil S52 sprays to and spatters plate S53, forms rich oil with the shallow bid air blending that gets into evaporation tube S56 and mixes gas, sprays from evaporation tube S56.Simultaneously from the stabilizer top oblong shaped orifices (S54, (S51, S57) rich oil with the evaporation tube ejection mixes the gas blending to the little air of S55) introducing.Because the little recirculating zone in the independent fuel feeding of evaporation tube S56, stabilizer receives protection, the concealment of v-stabilizer, guarantee the reliable and burning of igniting of stabilizer, play the effect of flame on duty.This shellfish vaporation-type flameholder is compared with conventional V-flame stabilizer; Advantage is igniting and the stable operation range that has enlarged oil-poor state, improves efficiency of combustion, and is particularly low with flow velocity when high at temperature of incoming flow; Superiority is obvious, and its oil-poor igniting oil-gas ratio can be little of 0.003.
Extraordinary V-type stabilizer on duty is that evaporation tube is contained in the little v-stabilizer with general V-type stabilizer difference on duty, and this little v-stabilizer does not have air admission hole, is formed by little v-stabilizer trailing edge and ripple and is interrupted the slit air inlet.Fuel oil gets into from evaporation tube, hits spattering on the plate, forms binary states and mixes gas, sprays in the stabilizer from the evaporation tube venthole, and the air blending with stabilizer ripple hole gets into forms flammable mixed gas.Pioneer's flame ignition main flow of utilizing little stable type to form is mixed gas, has good ignition quality and flame holding.
Flameholder on duty is the core component of fanjet after-burner and scramjet combustor, and the decision engine performance is had material impact.At present; Think that this shellfish stabilizer on duty has better ignition performance, flame holding and efficiency of combustion than V-flame stabilizer, double V-shaped flameholder, thin film evaporation v-shaped flame stabilizer, suction-type flameholder, extraordinary V-type stabilizer on duty, particularly low-pressure performance is superior.Yet, find that in a large amount of combustion experiments this shellfish stabilizer on duty surpasses 100m/s at low pressure 0.08Mpa and flow velocity, ignition difficulties just occurs, flame instability, with phenomenons such as huggings, its combustibility variation under the low-temp low-pressure particularly.To higher flight field development, flameholder on duty is proposed higher requirement with aircraft,, therefore, need the novel flameholder on duty of research to adapt to worse combustion conditions.
