ISRO GSLV-2

BANGALORE (BNS): Indian scientists are developing semi-cryogenic propulsion technology using kerosene which will help the nation to launch at least six-tone class satellite.

Addressing the 23rd national convention of aerospace engineers here, ISRO chairman K Radhakrishnan said the semi-cryogenic technology is part of ISRO's efforts to cut down costs of space projects. "...the cost becomes far, far less (in semi-cryogenic technology using kerosene)," he said.

“The cryogenic technology uses liquid hydrogen and liquid oxygen, whereas in semi-cryogenic technology, instead of liquid hydrogen, pure kerosene (aviation-grade) is used,” a report by PTI quoting him said.

The technology would enable the home-built GSLV rocket to launch six-tone class satellites. Currently India's GSLV-Mk II has the capacity to launch only satellites weighing a maximum of 2.2 tones.

GSLV-D3 would use indigenous cryogenic engine and stage. Indian Space Research Organisation scientists have been working on the cryogenic engine project since 1996.

"It's a major milestone in the development of a sophisticated propulsion technology in the country," Radhakrishnan said, adding, development of Indian cryogenic engine and stage will make the country self dependent in the launch technology.
