New advanced space launcher in 2018
Posted on: 01/Oct/2016 11:27:42 AM
ISRO launchers will soon be powered by an advanced Indian mega space launcher that can deliver ten-tonne and heavier communication satellites to space and using a semi-cryogenic engine. Currently, the government has approved the development of the semi-cryogenic stage alone.
When fitted suitably into a launch vehicle, it will see India putting satellites of the class of 6,000 to 10,000 kilos — or with some variations, lift even 15,000-kg payloads — to geostationary transfer orbits at 36,000 km. The engine is expected to triple or quadruple ISRO`s transportation ability.
Speaking about this, a senior official of the Vikram Sarabhai Space Centre at Thiruvananthapuram said, We plan to have an [semi-cryogenic] engine and stage capable of flight by the end of 2018 and try it on the GSLV-MkIII. This would readily boost Mk-III`s maximum lifting capability from 4,000 kg to 6,000 kg. The semi-cryogenic engine is getting fabricated. Testing of its pump and components has been going on. An engine testing facility is also getting set up at Mahendragiri, Apart from powering rockets to lift heavier satellites, it will also effectively lower the cost per kilogram to reach orbits, which is the goal of all space-faring nations. The GSLV-MkIII that we plan to test in December has a core liquid fuel stage. When the semi-cryogenic engine gets ready, our plan is to replace the liquid stage with the SCE. We straightaway get six-tonne payload capability, two tonnes over what Mark III can give. We can have a bigger semicryogenic stage with clustered engines, similar to what SpawceX did using nine Merlin engines. We can then get a payload of 15 tonnes in the GTO.
