- turbine nozzle
- Turbine stationary airfoils that precede each turbine blade set. They function to increase gas velocity and also direct the gases onto the turbine blade at an optimum angle.

Turbine — A turbine is a rotary engine that extracts energy from a fluid flow. Claude Burdin (1788 1873) coined the term from the Latin turbo , or vortex, during an 1828 engineering competition. Benoit Fourneyron (1802 1867), a student of Claude Burdin,… … Wikipedia
turbine stator — A ring of fixed blades upstream of each turbine rotor stage, onto which the turbine stators direct gas at an optimum angle. Also called inlet guide vanes. See inlet guide vanes and turbine nozzle … Aviation dictionary
turbine inlet temperature — The temperature taken in front of the first stage turbine nozzle vanes. This is the most critical temperature within the engine and is controlled by regulating the amount of fuel flow into the engine … Aviation dictionary

turbine — /terr bin, buyn/, n. any of various machines having a rotor, usually with vanes or blades, driven by the pressure, momentum, or reactive thrust of a moving fluid, as steam, water, hot gases, or air, either occurring in the form of free jets or as … Universalium
Turbine map — Each turbine in a gas turbine engine has an operating map. Complete maps are either based on turbine rig test results or are predicted by a special computer program. Alternatively, the map of a similar turbine can be suitably scaled. Description… … Wikipedia
nozzle diaphragm — The ring of stationary vanes directly ahead of the turbine wheel. The vanes in the nozzle diaphragm act as a series of converging ducts that accelerates the airflow as it leaves the combustors and directs the flow of hot gases into the turbine in … Aviation dictionary
