It is so nice to see that ISRO is seriously working on semi-cryogenic engine for GSLV MK-3.
1)According to Dr Sivan(LPSC),semi cryogenic engine will simply boost the payload carrying capacity from 4-5 tonnes class(to GTO) to 6-7 tonnes class--or an improvement of 2-tonnes straight! With semi-cryogenic engine India will achieve "throw-weight" parity with major european launchers for the first time!First test flight of Semi-cryogenic engine is slated for 2018.
2)Dr Sivan also alluded to various projects going on,to further enhance the payload capacity of GSLV MK3 to a whopping 15tonnes to GTO.He explained that ULV(unified launch vehicle)--or evolved version of GSLV MK3 will have strap on boosters with clustered liquid engine. This ULV flight is scheduled 2 years after semi cryogenic flight or in 2020. With clustered strap ons and a big cryogenic engine in upper stage ULV variants will have a massive payload carrying capacity of 15 tonnes to GTO.
3)ULV will eventually become india's standard launch vehicle thereby eliminating the need for GSLV MK-2 altogether. ULV without any strap ons will have the same capacity as enhanced GSLV MK2.
4)LPSC-the lab i visited in 2012,is also working on ion propulsion for satellites. This will reduce the weight of satellites to a great extent as nearly 40-50% weight of a satellite is fuel which it uses for raising orbit and attitude corrections throughout itz life.In fact ISRO first test fired their small ion drive in 2010--a test that failed because of failed GSLV MK3 launch.
