Indigenous cryogenic engine tested successfully

Chennai: In a major step, ISRO today successfully tested the indigenous cryogenic engine to be used to propel the country`s Geosynchronous Satellite Launch Vehicle. The test was conducted at the Liquid Propulsion Systems Centre at Mahendragiri in Tamil Nadu`s Tirunelveli district.

"The acceptance test of the indigenous cryogenic engine for the forthcoming GSLV-D5 flight was conducted successfully for 200 seconds at 17:10 hrs…," an ISRO statement said. "The performance of the engine was as predicted," it said. The maiden flight test of the indigenous cryogenic stage onboard GSLV-D3 failed in May 2010 after it developed a snag and the rocket plunged into the sea minutes after lift-off.

ISRO chief K Radhakrishnan had said last month that GSLV would undergo two more tests at the Mahendragiri facility. He had also said ISRO was planning a GSLV launch with Indian cryogenic engine during September-October. ISRO plans to fly two GSLV rockets at an interval of six months with the third one meant for the Chandrayaan-2 moon mission.
