Gas turbine engine is a machine which converts thermal energy into mechanical work. Gas turbine power plant is a gas turbine engine and all essential equipment necessary for the production of power in useful form. Compressor is a mechanical rotary component which compresses the working fluid.
Turbine is a mechanical rotary component which produces work by action of the working fluid.
Single-shaft gas turbine engine is a gas turbine engine in which all compressor and turbine stages are mechanically interconnected and operate at the same speed. Gas generator turbine is the turbine portion of a gas generator. 2.2.10 Precooler is a heat exchanger or evaporative cooler which reduces the temperature of the working fluid before initial compression. 2.2.11 Intercooler is a heat exchanger for cooling the working fluid between stages of compression. 2.2.12 Aftercooler is a heat exchanger for cooling the working fluid, following the last stage of compression.
