2. Vortex tube - Wikipedia

   en.wikipedia.org/wiki/Vortex_tube

   Vortex tube. The vortex tube, also known as the Ranque-Hilsch vortex tube, is a mechanical device that separates a compressed gas into hot and cold streams. The gas emerging from the hot end can reach temperatures of 200 °C (390 °F), and the gas emerging from the cold end can reach −50 °C (−60 °F). [1] It has no moving parts and is ...

3. Archimedes (rocket engine) - Wikipedia

   en.wikipedia.org/wiki/Archimedes_(rocket_engine)

   Archimedes is presented as a highly reusable liquid-propellant engine using methane and liquid oxygen in an oxidizer-rich staged combustion cycle. [1] [2] There are both sea-level and vacuum variants. The engine is mostly 3D printed, [7] with some of the biggest 3D printers in the world. The rationale for the cycle change from the original gas ...

4. Gas generator - Wikipedia

   en.wikipedia.org/wiki/Gas_generator

   A gas generator is a device for generating gas. A gas generator may create gas by a chemical reaction or from a solid or liquid source, when storing a pressurized gas is undesirable or impractical. The term often refers to a device that uses a rocket propellant to generate large quantities of gas. The gas is typically used to drive a turbine ...

5. Solid-propellant rocket - Wikipedia

   en.wikipedia.org/wiki/Solid-propellant_rocket

   The Space Shuttle was launched with the help of two solid-fuel boosters known as SRBs. A solid-propellant rocket or solid rocket is a rocket with a rocket engine that uses solid propellants ( fuel / oxidizer ). The earliest rockets were solid-fuel rockets powered by gunpowder; The inception of gunpowder rockets in warfare can be credited to the ...

7. Gas-generator cycle - Wikipedia

   en.wikipedia.org/wiki/Gas-generator_cycle

   The gas-generator cycle, also called open cycle, is one of the most commonly used power cycles in bipropellant liquid rocket engines. Propellant is burned in a gas generator (or "preburner") and the resulting hot gas is used to power the propellant pumps before being exhausted overboard and lost. Because of this loss, this type of engine is ...

8. Expander cycle - Wikipedia

   en.wikipedia.org/wiki/Expander_cycle

   The expander cycle is a power cycle of a bipropellant rocket engine. In this cycle, the fuel is used to cool the engine's combustion chamber, picking up heat and changing phase. The now heated and gaseous fuel then powers the turbine that drives the engine's fuel and oxidizer pumps before being injected into the combustion chamber and burned.

9. Gorniczy Agregat Gasniczy - Wikipedia

   en.wikipedia.org/wiki/Gorniczy_Agregat_Gasniczy

   The Górniczy Agregat Gaśniczy ( GAG) is a jet engine inertisation unit developed for use in mines, controlling and suppressing coal seam fires and neutralising firedamp situations. The unit was designed in Poland in the 1970s, its name roughly translates as "Mine Fire Suppression Apparatus". [1] [2] A GAG 3A unit was developed by the ...
