Background technology
Gas turbine is a kind of turbogenerator, and feature is to be completely dependent on combustion gas stream to produce thrust, is typically used as flying at a high speed
The power of machine, but oil consumption is higher than turbofan.Turbojet engine is divided into centrifugal and two kinds of axial-flow type, is centrifuged compared to rising
Formula turbojet engine, axial flow turbojet has cross section small, and the high advantage of compression ratio, current turbojet engine is most
For axial-flow type.The structure of gas turbine is made up of air intake duct, compressor, combustion chamber, turbine and jet pipe.Gas turbine belongs to heat
Released energy under one kind of machine, it then follows the acting principle of heat engine, under high pressure input energy, low pressure.Energy is exported from producing
Said in principle, turbogenerator and piston-mode motor are identicals, be required for air inlet, pressurizeed, burn and be vented this four
Stage, unlike, 4 stages are that timesharing is carried out successively in piston-mode motor, are then carried out continuously in gas turbine
Acting.
What air was initially entered is the air intake duct of engine, and the pressure of air-flow is improved through compressor, and air flows through compressor
When, compressor blade does work to air-flow, makes the pressure of air-flow, temperature rise.The high-temperature high-pressure fuel gas flowed out from combustion chamber,
Flow through turbine of the same compressor on same axle.The part interior energy of combustion gas expands in turbine is converted into mechanical energy, drives
Compressor rotates, in the gas turbine, and poised state downstream expands work done equal to compressor compressed air in turbine
The work(and driven accessary consumed overcomes the work(needed for friction.Combustion gas energy after burning before turbine is greatly increased, in turbine
Expansion be much larger than compression ratio in compressor, the pressure and temperature at turbine outlet is all more much higher than compressor inlet, starts
The thrust of machine is the energy by this Some gases.The high-temperature high-pressure fuel gas flowed out from turbine, continue in jet pipe
Expansion, is discharged backward with high speed along engine shaft to from spout.Due to gas turbine spray flue-gas temperature be up to 500 DEG C with
On, it is a kind of waste of energy to be expelled directly out.
The content of the invention
