  3. Exhaust mixer - Wikipedia

    en.wikipedia.org/wiki/Exhaust_mixer

    Exhaust mixer of a JT8D engine of a Boeing 737-200. In aviation, an exhaust mixer / flow mixer is a feature of many turbofan engines, where slower, colder bypass air is mixed with faster, hotter core exhaust gases, before exhausting to atmospheric pressure through a common (mixed flow) propelling nozzle.

    Kort nozzle The towboat Dolphin I in a floating drydock on the Mississippi River in Algiers, Louisiana. A ducted propeller, also known as a Kort nozzle, is a marine propeller fitted with a non-rotating nozzle. It is used to improve the efficiency of the propeller and is especially used on heavily loaded propellers or propellers with limited ...

  5. de Laval nozzle - Wikipedia

    en.wikipedia.org/wiki/De_Laval_nozzle

    A de Laval nozzle (or convergent-divergent nozzle, CD nozzle or con-di nozzle) is a tube which is pinched in the middle, with a rapid convergence and gradual divergence. It is used to accelerate a compressible fluid to supersonic speeds in the axial (thrust) direction, by converting the thermal energy of the flow into kinetic energy .

  6. SpaceX rocket engines - Wikipedia

    en.wikipedia.org/wiki/SpaceX_rocket_engines

    Channels etched into the Merlin 1D nozzle enable regenerative cooling preventing exhaust heat from melting it.. Since the founding of SpaceX in 2002, the company has developed four families of rocket engines — Merlin, Kestrel, Draco and SuperDraco — and since 2016 developed the Raptor methane rocket engine and after 2020, a line of methalox thrusters.

  7. Shut-off nozzle - Wikipedia

    en.wikipedia.org/wiki/Shut-off_nozzle

    This nozzle type is fitted with a rotatable bolt assembly which has a cavity equal in size to the melt channel. In its open position, the bolt cavity is directly aligned with the melt stream. When the actuator rotates the bolt assembly, the cavity becomes misaligned and thus shuts off the melt flow.

  8. Spray nozzle - Wikipedia

    en.wikipedia.org/wiki/Spray_nozzle

    Spray nozzles can have one or more outlets; a multiple outlet nozzle is known as a compound nozzle. Multiple outlets on nozzles are present on spray balls, which have been used in the brewing industry for many years for cleaning casks and kegs. [2] Spray nozzles range from those for heavy duty industrial uses to light duty spray cans or spray ...

  9. SuperDraco - Wikipedia

    en.wikipedia.org/wiki/SuperDraco

    SuperDraco is a hypergolic propellant rocket engine designed and built by SpaceX.It is part of the SpaceX Draco family of rocket engines. A redundant array of eight SuperDraco engines provides fault-tolerant propulsion for use as a launch escape system for the SpaceX Dragon 2, a passenger-carrying space capsule.
