The Indian Space Research Organisation (ISRO) has successfully tested high-thrust cryogenic engine CE-20 of the GSLV Mark 3 (LVM3) rocket for the upper stage at its Propulsion Research Center in Mahendragiri, Tamil Nadu lasted for 640 seconds and paved the way for the first developmental flight of the GSLV Mark 3 in December 2016.
It was conducted with Mixture Ratio Controller (MRC) in a closed loop mode. Using Liquid Hydrogen at 253 degrees C and Liquid Oxygen at 193 degrees C as propellants, the high-thrust cryogenic engine (CE20) generates power of approximately 2 MW. Developed at the Liquid Propulsion System centre (LPSC) here, the engine had already undergone two short-duration tests for engine ignition and steady state performance.
Last year, the first developmental engine completed different hot tests in various operating regimes. The third engine identified for flight use will be vacuum tested in the high altitude test facility as part of the flight acceptance test.
ISRO chairman A.S. Kiran Kumar termed the test as a phenomenal achievement in the shortest time. Earlier, Mr. Kumar was talking to the media on the sidelines of a workshop organised by the VSSC and the Society for Aerospace Quality and Reliability (SAQR). The biggest rocket made in India, the Mk3 will be capable of launching four-tonne satellites into geosynchronous orbit. India is sixth spacefarer after US, Russia, the European Space Agency (ESA), China and Japan to develop a cryogenic engine.
