Gas-generator cycle (rocket) — The gas generator cycle (also known as open cycle) is a power cycle of a bipropellant rocket engine. Some of the propellant is burned in a gas generator and the resulting hot gas is used to power the engine s pumps. The gas is then… … Wikipedia
Cycle detection — This article is about iterated functions. For another use, see Cycle detection (graph theory). In computer science, cycle detection is the algorithmic problem of finding a cycle in a sequence of iterated function values. For any function ƒ that… … Wikipedia

Expander cycle (rocket) — The expander cycle is a power cycle of a bipropellant rocket engine meant to improve the efficiency of fuel delivery.In an expander cycle, the fuel is heated before it is combusted, usually with waste heat from the main combustion chamber. As the … Wikipedia
Staged combustion cycle (rocket) — Staged combustion rocket cycle. Usually, all of the fuel and a portion of the oxidizer are fed through the pre burner (fuel rich) to power the pumps. An oxygen rich circuit is possible also, but less common because of the metallurgy required. The … Wikipedia
Gas generator — 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,… … Wikipedia
Pressure-fed cycle (rocket) — The pressure fed cycle 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 maintain adequate flow, the tank pressures must exceed… … Wikipedia
MHD generator — Energy portal The MHD (magnetohydrodynamic) generator or dynamo transforms thermal energy or kinetic energy directly into electricity. MHD generators are different from traditional electric generators in that they can operate at high tempera … Wikipedia
