Nozzle
71Plug nozzle — The plug nozzle is a type of rocket engine 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, but unlike the aerospike, the plug design is… …
72variable-geometry nozzle — A nozzle whose diameter can be changed. It is normally in the shape of a convergent nozzle at subsonic speeds and of a convergent divergent nozzle at supersonic speeds, or when a reheat is on. A variable nozzle permits the use of after burner… …
73Stepped nozzle — A stepped nozzle is a de Laval rocket nozzle which has altitude compensating properties.The characteristic of this kind of nozzle is that part of the way along the inside of the nozzle there is a straightening of the curve of the nozzle contour,… …
74pop-open nozzle — A nozzle on a jet engine with a variable geometry outlet. This type of nozzle often is found on engines with afterburning. The nozzle generally is fully open (the largest dimension) at idle and progressively closes to the fully closed position at …
75Altitude compensating nozzle — An altitude compensating nozzle is a class of rocket engine nozzles that are designed to operate efficiently across a wide range of altitudes.Conventional designsThe basic concept of any engine bell is to efficiently direct the flow of exhaust… …
76secondary nozzle/exhaust nozzle — An annular nozzle surrounding the primary nozzle of a jet engine. A cooling airflow passes through the secondary nozzle. Separate secondary for fan flow and core engine flow …
77Monitor nozzle — A nozzle capable of turning completely round in a horizontal plane and having a limited play in a vertical plane, used in hydraulic mining, fire extinguishing apparatus, etc. [Webster 1913 Suppl.] …
78Kort nozzle — The Kort nozzle is a shrouded, ducted propeller assembly for marine propulsion. The hydrodynamic design of the shroud, which is shaped like a foil, offers advantages for certain conditions over bare propellers.Kort nozzles or ducted propellers… …
79bayonet fueling nozzle — A type of nozzle used for pressure or single point fueling. The nozzle is connected into an aircraft receptacle and the handle is turned to lock the nozzle in place …
80exhaust nozzle — That part of an exhaust cone that opens into the tailpipe; also referred to as the nozzle shaped end of the tailpipe. The nozzle acts as an orifice whose size determines the density and velocity of outgoing air. In some cases, the nozzle geometry …
