  • Jet engine performance — This article describes how jet engine performance is estimated during the design phase. Similar techniques are used once the engine has been built and is being tested, except the performance of individual components, rather than being assumed, is …   Wikipedia

  • Propelling nozzle — A propelling nozzle is a component of a jet engine that is found at the tail of the engine that operates to form an exhaust jet and to maximise the use of the exhaust gas s energy throughout the engine so that the maximum overall thrust is… …   Wikipedia

  • Expanding nozzle — The expanding nozzle is a type of rocket nozzle that, unlike traditional designs, maintains its efficiency at a wide range of altitudes. It is a member of the class of altitude compensating nozzles, a class that also includes the plug nozzle and… …   Wikipedia

  • Rocket engine nozzle — A rocket engine nozzle is a propelling nozzle usually of the de Laval type used in a rocket engine to expand and accelerate the combustion gases, from burning propellants, so that the exhaust gases exit the nozzle at hypersonic… …   Wikipedia

  • Bell nozzle — The Bell shaped or Contour nozzle is probably the most commonly used shaped nozzle. It has a high angle expansion section ( 20 to 50 degrees) right behind the nozzle throat; this is followed by a gradual reversal of nozzle contour slope so that… …   Wikipedia

  • Spray nozzle — A spray nozzle is a device that facilitates the formation of spray. When a liquid is dispersed as a stream of droplets (atomization), it is called a spray. Spray nozzles are used to achieve two primary functions: increase liquid surface area to… …   Wikipedia
