For heavy rocket launch, India successfully tested cryogenic engine that would be unveiled as the country’s second moon mission on 3rd January 2019, on Friday reports the space agency.
In a statement, the state-run ISRO (Indian Space Research Organisation) stated that “The cryogenic engine of the Geo Satellite Launch Vehicle (GSLV MK-III) in the upper stage has been tested for the Chandrayaan-2 Mission.”
On Thursday, the crucial test was done for over 25 seconds at the space agency’s Propulsion site in Mahendragiri, Tamil Nadu, which is located 685km southwest of Chennai.
The statement reads that “The upper stage of the heavy rocket is powered by a cryogenic engine, which develops a nominal thrust of 186.36 kN (kilo Newton) with a specific impulse of 442 seconds in vacuum.”
The supercooled engine was operated on gas generator cycle using hydrogen and liquid oxygen (LH2 & LOX) or oxidizer.
In the statement, it reads that “The test demonstrated steady state operation of an engine.”
The flight successfully passed the hot test of cryo, which was performed at the high-altitude test facility in the complex.
The statement continued, “The performance of all engine subsystems was observed to be normal during the hot test.”
In Andhra Pradesh’s Sriharikota, the second moon lunar will be launched from the port, which is about 90km northeast of Chennai, with a rover and lander a decade after the first lunar mission in October 2008 around its orbit.
