Indigenously Developed Cryogenic Rocket Engine Successfully Tested

Highlights of the test:
India’s first indigenously designed High Thrust Cryogenic rocket engine was successfully hot tested.
The engine will be used for powering the next generation GSLV Mk-III launch vehicle of ISRO.
This cryogenic engine of C25 Stage operates on Gas Generator Cycle using extremely low temperature propellants – Liquid Hydrogen & Liquid Oxygen.
The parts of the engine are all made in India & assembled by ISRO.
Cryogenic Engine:
A cryogenic rocket engine is a rocket engine that uses a cryogenic fuel. Currently, six governments have successfully developed and deployed cryogenic rocket engines: India, United States, European Space Agency, Russia, China, Japan.
Cryogenic fuels are fuels that require storage at extremely low temperatures in order to maintain them in a liquid state. These fuels are used in space because ordinary fuel cannot be used there, due to absence of an environment that supports combustion. Cryogenic fuels most often constitute liquefied gases such as liquid hydrogen.
About GSLV Mark III:
The GSLV-Mark III, is a launch vehicle developed by the Indian Space Research Organization (ISRO).
GSLV Mk III is designed to make ISRO self reliant in launching heavier communication satellites which weigh 4500 to 5000 kg. (previously cryogenic technology was supplied by Russia).
This space launch vehicle will take India to the next level of commercially launching vehicles. This is a multimillion dollar market.
The vehicle envisages multi-mission launch capability for GTO, LEO, Polar and intermediate circular orbits.
GSLV-Mk III is designed to be a 3 stage vehicle.
First stage comprises two identical S200 Large Solid Booster (LSB) with 200 tonnesolid propellant
Second stage is the liquid stage
The third stage is the C25 cryo stage.
The GSLV-III features an Indian cryogenic third stage and a higher payload capacity than the current GSLV.
