2. Reaction Motors XLR99 - Wikipedia

   en.wikipedia.org/wiki/Reaction_Motors_XLR99

   Like many other liquid-fuel rocket engines, the XLR99s used regenerative cooling, in that the thrust chamber and nozzle had tubing surrounding it, through which the propellant and oxidizer passed before being burned. This kept the engine cool, and preheated the fuel. The basic engine has a mass of 910 lb (410 kg).

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. 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.

5. Pressure-fed engine - Wikipedia

   en.wikipedia.org/wiki/Pressure-fed_engine

   Pressure-fed rocket cycle. Propellant tanks are pressurized to directly supply fuel and oxidizer to the engine, eliminating the need for turbopumps. The pressure-fed engine is a class of rocket engine designs. A separate gas supply, usually helium, pressurizes the propellant tanks to force fuel and oxidizer to the combustion chamber. To ...

6. Oxy-fuel combustion process - Wikipedia

   en.wikipedia.org/wiki/Oxy-fuel_combustion_process

   However, oxy-fuel is a viable alternative to removing CO 2 from the flue gas from a conventional air-fired fossil fuel plant. However, an oxygen concentrator might be able to help, as it simply removes nitrogen. In industries other than power generation, oxy-fuel combustion can be competitive due to higher sensible heat availability. Oxy-fuel ...

7. Staged combustion cycle - Wikipedia

   en.wikipedia.org/wiki/Staged_combustion_cycle

   Full-flow staged combustion (FFSC) is a twin-shaft staged combustion fuel cycle design that uses both oxidizer-rich and fuel-rich preburners where the entire supply of both propellants passes through the turbines. [5] The fuel turbopump is driven by the fuel-rich preburner, and the oxidizer turbopump is driven by the oxidizer-rich preburner. [6 ...

9. Electric-pump-fed engine - Wikipedia

   en.wikipedia.org/wiki/Electric-pump-fed_engine

   The electric-pump-fed engine is a bipropellant rocket engine in which the fuel pumps are electrically powered, and so all of the input propellant is directly burned in the main combustion chamber, and none is diverted to drive the pumps. This differs from traditional rocket engine designs, in which the pumps are driven by a portion of the input ...
