A gas generator usually refers to a propellant mixture, often similar to a solid rocket propellant, that burns to produce large volumes of gas. It is similar to a rocket propellant, but is usually designed to produce large volumes of cool gas, instead of maximizing the energy available. The low temperature allows the gas to be put to use more easily in many applications. Gas generators are used to power turbopumps in rocket motors, to deploy airbags, and in other cases where large volumes of gas are needed, and storing it as a pressurized gas is undesirable or impractical. A propellant is a material that is used to move an object by applying a motive force. ... The Space Shuttle Columbia is initially launched using solid-fuel boosters Solid rockets are rockets with a motor that uses solid propellants (fuel/oxidizer). ... A gas is one of the four main phases of matter (after solid and liquid, and followed by plasma), that subsequently appear as a solid material is subjected to increasingly higher temperatures. ... A Redstone rocket, part of the Mercury program A rocket is a vehicle, missile or aircraft which obtains thrust by the reaction to the ejection of fast moving exhaust gas from within a rocket engine. ... A turbopump can refer to either of two types of pump. ... An airbag is a flexible membrane or envelope, inflatable to contain air or some other gas. ...

A gas generator cycle can also specifically refer to a way of designing a turbopump-fed liquid rocket engine, where some of the propellant is burned to drive the turbopump, and the exhaust is dumped overboard (usually through a nozzle) instead of being fed into the main combustion chamber. Many liquid rockets are designed this way, for example the Saturn V F-1 engine. A liquid rocket engine has fuel and oxidiser in liquid form, as opposed to a solid rocket or hybrid rocket. ... Rocket Nozzle A nozzle is a mechanical device designed to control the characteristics of a fluid flow as it exits from an enclosed chamber into some medium. ... A combustion chamber is part of an engine in which fuel is burned. ... The Saturn V (popularly known as the Moon Rocket) was a multistage liquid-fuel expendable rocket used by NASAs Apollo and Skylab programs. ... F-1 Rocket Engine Specifications. ...

Another good example is the V-2 rocket, which used hydrogen peroxide decomposed by a liquid sodium permanganate catalyst solution as a gas generator. This was used to drive the main turbopump to pressurize the LOX-ethanol propellants. The V-2 rocket or Vergeltungswaffe 2 (Vengeance weapon 2) was an early ballistic missile used by the German Army during the later stages of World War II against mostly British and Belgian targets. ... Hydrogen peroxide (H2O2) is a clear liquid, slightly more viscous than water, that has strong oxidizing properties and is therefore a powerful bleaching agent that has found use as a disinfectant, as an oxidizer, and in rocketry (particularly in high concentrations as high test peroxide (HTP)) as a monopropellant and... A catalyst (Greek: καταλύτης, catalytēs) is a substance that accelerates the rate (speed) of a chemical reaction (see also catalysis). ... A turbopump can refer to either of two types of pump. ... Lox can stand for any of several things: Lox (salmon) - a type of salmon produce LOx (oxidizer) - liquid oxygen used as oxidizer in aerospace The Lox - was a Yonkers, NY-based rap trio This is a disambiguation page — a list of articles associated with the same title. ...
