Evolution of Gas Turbine, Its Usage, and Types
Examples of gas turbine: (1) turbojet, (2) turboprop, (3) turboshaft (shown as electric generator), (4) high-bypass turbofan, (5) low-bypass afterburning turbofan Gas Turbine A gas turbine or gas turbine engine is a type of continuous flow internal combustion engine. The main parts common to all gas turbine engines form the power-producing part (known as the gas generator or core) and are, in the direction of flow: • a rotating gas compressor • a combustor • a compressor-driving turbine. Additional components have to be added to the gas generator to suit its application. Common to all is an air inlet but with different configurations to suit the requirements of marine use, land use or flight at speeds varying from stationary to supersonic. A propelling nozzle is added to produce thrust for flight. An extra turbine is added to drive a propeller (turboprop) or ducted fan (turbofan) to reduce fuel con...
