• De Laval nozzle — A de Laval nozzle (or convergent divergent nozzle, CD nozzle or con di nozzle) is a tube that is pinched in the middle, making an hourglass shape. It is used as a means of accelerating the flow of a gas passing through it to a supersonic speed.… …   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

• 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
