What are the basic engine components of gas turbine engine?
A gas turbine is an internal combustion engine that operates with rotary rather than reciprocating motion. Gas turbines are composed of three main components: compressor, combustor and power turbine.
What are the parts of turbine?
15.1 includes 14 major components common to many modern wind turbines: three blades, three pitch bearings, a hub, main bearing, main shaft, gearbox, generator, main frame, yaw bearing, and tower. Some turbine designs may include more or fewer major components [19].
What are the major components of gas turbine?
The gas turbine has three major sections, namely the compressor, combustor and turbine (although, from a materials perspective, the other major component groups – rotor, casing and auxiliaries – are also of interest). The compressor, combustor and turbine sections are highlighted in Fig. 1.1.
How do gas turbine engines work?
As hot combustion gas expands through the turbine, it spins the rotating blades. The rotating blades perform a dual function: they drive the compressor to draw more pressurized air into the combustion section, and they spin a generator to produce electricity.
What is rotor in turbine?
The rotor connects to the generator, either directly (if it’s a direct drive turbine) or through a shaft and a series of gears (a gearbox) that speed up the rotation and allow for a physically smaller generator. This translation of aerodynamic force to rotation of a generator creates electricity.
How many turbine stages are there in a gas turbine engine?
The turbine is normally based on the reaction principle with the hot gases expanding through up to eight stages using one- or two-spooled turbines.
How many types of gas turbines are there?
Generally, three specific types of gas turbine compressors are available: an axial compressor, a centrifugal compressor, and a compressor with a mixed flow.
