ISRO Successfully Tests Cryogenic Engine for Upper Stage of GSLV Mk III
Indian Space Research Organisation (ISRO) successfully tested its indigenously developed Cryogenic engine designated as C25, on January 25, 2017 for 50 seconds at ISRO Propulsion Complex (IPRC) at Mahendragiri in Tamil Nadu. The cryogenic engine has been developed for use in the Upper Stage ofGSLV Mk III rocket, which is scheduled to be launched within the first quarter of 2017. Cryogenic engines are used in the upper stage of a rocket launch as they provide the maximum thrust to a launcher vehicle. This was the first test in a series of two tests. The next one has been planned for flight duration of 640 seconds.
iv. The C25 stage is the most powerful upper stage developed by ISRO and uses Liquid Oxygen and Liquid Hydrogen propellant combination.
v. GSLV MkIII is a next generation launch vehicle of ISRO, capable of launching 4 ton class spacecraft in Geosynchronous Transfer Orbit (GTO).
