India Among Six Nations With Cryogenic Rocket Engine Technology

The CE20 is an advanced cryogenic rocket engine developed indigenously by the Indian Space Research Organisation (ISRO). It powers the upper stage of the LVM3 launch vehicle and strengthens India’s capability in heavy-lift launch systems and space missions.

CE20 Cryogenic Engine & Cryogenic Propulsion:

Aspect	Key Details
Engine Name	CE20 cryogenic rocket engine.
Developer	Indian Space Research Organisation (ISRO).
Technology Status	Cryogenic rocket technology is possessed by only six countries: USA, Russia, Japan, France, China and India.
Launch Vehicle Usage	Used in the third stage of the LVM3 (Launch Vehicle Mark-3) rocket.
Strategic Significance	Enhances India’s payload capability for future missions and supports programmes such as Gaganyaan while strengthening technological self-reliance.
Cryogenic Engine Definition	A cryogenic rocket engine uses liquefied gases as fuel and oxidizer to produce thrust.
Meaning of Cryogenic	Refers to substances maintained at extremely low temperatures, typically below −150°C.
Typical Propellants	Liquid Oxygen (LOX) as oxidizer and Liquid Hydrogen (LH2) as fuel.
Working Principle	Functions as a reaction engine that generates thrust by expelling high-speed exhaust gases in one direction, producing an equal and opposite reaction that propels the rocket forward.
