CE20 is an advanced cryogenic rocket engine, indigenously developed by the Indian Space Research Organisation (ISRO).
- Only 6 countries possess this technology i.e. USA, Russia, Japan, France, China and India.
- Significance: Used in third stage of LVM3 launch vehicle; for enhancing future payload capacities (e.g. Gaganyaan Programme); and becoming self-reliant.
About Cryogenic Engines
- Definition: A cryogenic engine is a type of rocket engine that utilizes liquefied gases for its fuel and oxidizers.
- The term "cryogenic" signifies that these liquefied gases must be kept at extremely low temperatures (below -150°C).
- Types of Propellants Used: Cryogenic engines typically employ Liquid Oxygen (LOX) and Liquid Hydrogen (LH2).
- Principle of Operation: A cryogenic engine is a reaction enginewhich generates thrust by expelling high-speed exhaust gases in one direction, producing an equal and opposite reaction that pushes the rocket forward.
