Aerospike engine, a rocket engine without a traditional rocket nozzle
Following Carl's completion of these flights for the Navy, NACA technicians at the High-Speed Flight Research Station (HSFRS) near Mojave, California, outfitted the LR-8 engine's combustion chambers with nozzle extensions to prevent the exhaust gas from affecting the rudders at supersonic speeds.
An alternative is to use an enema nozzle which has an intake end which is compatible with a standard hypodermic syringe.
In 1955, vice president Richard M. Nixon was photographed at a gasoline pump "fueling" a Child's Sport Car in a March of Dimes "Fill 'Er Up for Polio" publicity campaign while holding the pump nozzle at the car's rear.
The i-CTDi engine uses a variable-nozzle turbocharger from Honeywell.
The Kylchap was not the only advanced steam locomotive exhaust: another design, the Lemaître, had some success in France and England; noted Argentinian engineer Livio Dante Porta designed several, the Kylpor, Lempor and Lemprex designs; and several U.S. railroads including the Norfolk & Western used a concentric nozzle known as the waffle iron exhaust.

The Kylchap steam locomotive exhaust system was designed and patented by French steam engineer André Chapelon, using a second-stage nozzle designed by the Finnish engineer Kyösti Kylälä and known as the Kylälä spreader; thus the name KylChap for this design.
Later the French engineer André Chapelon, developed and improved the invention by using a second-stage nozzle and adopted the name Kylchap for this design.
A VFW VAK 191B aircraft fitted with an RB.193-12 is on display at the Deutsches Museum Flugwerft Schleissheim, panels have been removed to allow viewing of the rotating nozzle and mechanisms.
Through the influence of electric field, the liquid coming out of the nozzle takes a conical shape (Taylor cone) and at the apex of the cone a thin jet emanates which disintegrates into very fine and small positively charged droplets under the influence of Rayleigh charge limt.
An unusual example of the turboshaft principle is the Pratt & Whitney F135-PW-600 engine for the STOVL F-35B - in conventional mode it operates as a turbofan, but when powering the LiftFan, it switches partially to turboshaft mode to send power forward through a shaft (like a turboprop) and partially to turbojet mode to continue to send thrust to the rear nozzle.
