Description
Technical field
The present invention relates to a kind of air compression system and engine system, and in particular to a kind of efficient pressure of spiral-flow type air inlet
Mechanism of qi and engine system and its application method, belong to machine power field.
Background technology
Compressor (compressor)：The blade rotated at a high speed is utilized in gas-turbine unit to air work done to improve
The part of air pressure.Compressor can be divided into the centrifugal and major class of axial-flow type two, and centrifugal-flow compressor is by inducer, impeller, expansion
Depressor etc. forms.The inducer that air enters compressor by air intake duct, is rotated together with impeller by compressor is guided into
Impeller.Under high-speed rotating impeller effect, air is got rid of to impeller outer edge, pressure by centrifugal force from impeller central and also gradually stepped up,
Speed reduces after entering diffuser by the air of impeller outflow, and pressure improves again, finally flows out compressor by escape pipe.Axle stream
Formula compressor air predominantly axially flows in axial-flow compressor.It is (also known as whole by rotor (also known as active wheel) and stator
Flow device) two parts composition.One-level, the pressure ratio very little of single-stage, in order to obtain are formed by row's rotor blade and row's stator blade
Higher pressure ratio is obtained, typically all uses multilevel hierarchy.After air is pressurized step by step in compressor, density and temperature are also step by step
Improve.
Under certain rotating speed, when the pressure ratio of compressor increases to a certain numerical value, compressor will enter unstable
Working condition, it is easy to surge occurs, makes whole system produce the air-flow axial pulse of low frequency large amplitude, or even moment can occur
The phenomenon that air-flow flows backwards.Compressor surge may cause leaf destruction, structural failure, combustion chamber overtemperature and engine misses to stop
Car.
Using traditional small bypass ratio turbofan.Turbofan has inside and outside two ducts, it outer
Contain fan be in airplane intake, can be worked transonic speed or during supersonic flight, have compared to spiral shell slurry engine and imitate
The advantages of rate is high.For fanjet compared with turbojet engine, it has higher propulsive efficiency and larger thrust.And adopt
After turbofan, adverse effect will not be brought to propulsive efficiency by improving turbine inlet temperature for the raising thermal efficiency.And
And the cold air of by-pass air duct can form cold air film at turbine position, reduce infringement of the high-temperature fuel gas to turbine before turbine.
And by-pass air duct air blends with turbine after-burning gas phase, be advantageous to increase thrust and reduce noise.
In the prior art, most of compressor selects axial-flow compressor.Flowing of the air in axial-flow type is compressor
The almost parallel work wheel shaft in direction, using being that its flowing makes its easy tissue multistage pressure in structure the advantages of compressor in this
Contracting, higher compressor overall pressure pressure ratio is obtained with all relatively low seamless pressure ratio of every one-level.Every grade of boost pressure
Between i1.15-1.35 so that without change direction drastically when air flows through every grade blade passage, flow losses are reduced, thus
Compressor efficiency is high.Especially it is that the more other kinds of compressor of axial-flow compressor is easier to obtain higher pressure in big flow
Mechanism of qi efficiency, multiatage axial flow compressor also have a big flow, high efficiency, the advantages of small windward side.
Using drum disk rotor, the bending rigidity of drum type rotor and the energy for bearing big centrifugal load of disk rotor are taken into account
Power, specially hybrid drum rotor, using the rotor structure of this form, have detachable rotor and non-dismountable rotor concurrently
Advantage, it is less high to manufacturing technology and technological requirement, while wide selection space has also been provided designers with, and convenient inspection
Look into, repair and change.
Working-blade employs controlled diffusion airfoil, blade profile thickness and curvature by optimal distribution.Essentially eliminate boundary-layer
Separation, add compressor valid circulation area, improve compressor efficiency.The chord of foil of blade profile is wider, front and rear thicker, has
Preferable anticorrosive and impact resistance.The excessively curved blade in end is to reduce the secondary damage caused by blade end walls boundary-layer
Lose, thus blade tip and root is forward and backward around particularly being bent.This high-effect blade of a new generation, makes compressor
Stage efficiency and the characteristic of compressor have obtained further raising.
Such compressor has following defect：First, because the blade of compressor is longer, and the curvature of each position of blade
Difference, the power that the air for causing whole compressor blade diverse location to enter is compressed differ, the air after blade
Compression ratio it is different, the air compression ratio of blade edge (periphery) is big, the air compression ratio of blade center (close to the center of circle) position
It is small, cause the air of blade edge (periphery) to shift to blade center (close to the center of circle) position after compressing, escape from blade center position
Compressor is escaped, causes the actual efficiency of compressor low；2nd, because the blade of compressor is longer, surge is obvious, makes unit
Strong vibration, thrust bearing shoe valve overload is caused, the damage of compressor can be caused within a very short time；3rd, in compressor rotor and
Between stator, as between rotor blade tip and casing, between rectifier inner ring and rotor drum, all deposited between rotor front/rear end and casing
In air loss, compressor efficiency is had a strong impact on.
