The free power turbine is in purple. A free-turbine turboshaft is a form of turboshaft or turboprop gas turbine engine where the power is extracted from the exhaust stream of a gas turbine by an independent turbine, downstream of the gas turbine. The power turbine is not mechanically connected to the turbines that drive the compressors, hence ...
A turbo generator is an electric generator connected to the shaft of a water turbine or steam turbine or gas turbine for the generation of electric power. [note 1] Large steam-powered turbo generators provide the majority of the world's electricity and are also used by steam-powered turbo-electric ships. [1]

Free-piston engine used as a gas generator to drive a turbine. A free-piston engine is a linear, 'crankless' internal combustion engine, in which the piston motion is not controlled by a crankshaft but determined by the interaction of forces from the combustion chamber gases, a rebound device (e.g., a piston in a closed cylinder) and a load device (e.g. a gas compressor or a linear alternator).
Invented. 1884 (140 years ago)(1884) A steam turbine is a machine that extracts thermal energy from pressurized steam and uses it to do mechanical work on a rotating output shaft. Its modern manifestation was invented by Charles Parsons in 1884. [ 1 ][ 2 ] Fabrication of a modern steam turbine involves advanced metalwork to form high-grade ...
A gas turbine, gas turbine engine, or also known by its old name internal combustion turbine, is a type of continuous flow internal combustion engine. [1] 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:
