1Aerospace Engineering Laboratory II 2145392 Gas TurbineScp
2Introduction Fluid machinery Fluid machine that adds energy to the fluid is called, pump, compressor, blower and fan.Fluid machine that extracts energy from the fluid is called turbine.
3Introduction Fluid machinery For fluid machines of dynamic type, the machines can be further divided according to the flow direction (respect to the rotating shaft) asThe radial flow machine: radial flow compressor, radial flow turbine.The axial flow machine: axial flow compressor, axial flow turbine.The mixed flow machine.
4Introduction Gas Turbine Gas Turbine is usually referred to a unit consisted of compressor, combustion chamber and turbine.Gas Turbine convert heat energy of a fuel into mechanical energy.
14Piston engine vs Gas turbine engine Advantages:Gas turbine engines have a great power-to-weight ratio compared to reciprocating engines. The flow of the fluid in the process can be classified as steady flow.Disadvantages:The main disadvantage of gas turbines is that, compared to a reciprocating engine of the same size, they are expensive, and they prefer a constant rather than a fluctuating load.
15Performance of gas turbine unit Study the actual working cycle of the gas turbine unit.Study the performance of the gas turbine unit.
