turbine nozzle


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

  • nozzle guide vanes — The stator blades of a turbine. They are convex and shaped like airfoils. They direct the airflow onto the turbine blades while at the same time converting pressure energy into kinetic energy. Gases coming from the combustion chamber pass through …   Aviation dictionary
