Stage, unlike, 4 stages are that timesharing carries out successively in piston-mode motor, are then carried out continuously in gas turbine
Acting.
What air 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 raising.The high-temperature high-pressure fuel gas flowed out from combustion chamber,
Flow through turbine of the same compressor on same axis.The part interior energy of combustion gas expands in turbine is converted into mechanical energy, drives
Compressor rotates, and in the gas turbine, equilibrium 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 greatly increases, in turbine
Expansion much larger than the 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, continues 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.
