ABSTRACT
Gas turbines are steady-flow power machines in which a gas (usually air) is compressed, heated, and expanded for the purpose of generating power. The term turbine is the component that delivers power from the gas as it expands; it is also called an expander. The term gas turbine refers to a complete power machine. The term gas turbine is often shortened to simply turbine, which can lead to confusion with the term for an expander.
