  2. 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 .

  3. Propelling nozzle - Wikipedia

    en.wikipedia.org/wiki/Propelling_nozzle

    The convergent nozzle was replaced with a C-D nozzle on the same engine J57 in the same aircraft F-101. The increased thrust from the C-D nozzle (2,000 lb, 910 kg at sea-level take-off) on this engine raised the speed from Mach 1.6 to almost 2.0 enabling the Air Force to set a world's speed record of 1,207.6 mph (1,943.4 km/h) which was just ...

  4. Nozzle - Wikipedia

    en.wikipedia.org/wiki/Nozzle

    A de Laval nozzle has a convergent section followed by a divergent section and is often called a convergent-divergent (CD) nozzle ("con-di nozzle"). Convergent nozzles accelerate subsonic fluids. If the nozzle pressure ratio is high enough, then the flow will reach sonic velocity at the narrowest point (i.e. the nozzle throat). In this ...

  6. Components of jet engines - Wikipedia

    en.wikipedia.org/wiki/Components_of_jet_engines

    Exhaust or nozzle — Turbine exhaust gases pass through the propelling nozzle to produce a high velocity jet. The nozzle is usually convergent with a fixed flow area. Supersonic nozzle — For high nozzle pressure ratios (Nozzle Entry Pressure/Ambient Pressure) a convergent-divergent (de Laval) nozzle is used. The expansion to atmospheric ...

    Behati Prinsloo is playing Santa!. The model, 36, revealed how she and husband Adam Levine, 45, spent the holidays with their daughters Dusty Rose, 8, and Gio Grace, 6, and their 1-year-old son in ...

  8. Turbojet - Wikipedia

    en.wikipedia.org/wiki/Turbojet

    The nozzle pressure ratio on a turbojet is high enough at higher thrust settings to cause the nozzle to choke. If, however, a convergent-divergent de Laval nozzle is fitted, the divergent (increasing flow area) section allows the gases to reach supersonic velocity within the divergent section. Additional thrust is generated by the higher ...
