The Vikas is a liquid fueled rocket engine built by Indian Space Research Organisation (ISRO).[7] It was developed by Nambi Narayanan and his team during the 1970s.[8] It is used in the Polar Satellite Launch Vehicle (PSLV) and the Geosynchronous Satellite Launch Vehicle (GSLV) series of expendable launch vehicles for space launch use. It is similar to the Viking.

The engine is used as the second stage of both the PSLV and the GSLV launch vehicles, with four strap-on boosters. The engine is also capable of gimballing. The GSLV MK-3 rocket uses two Vikas engines in its core stage. The propellant loading for GSLV MK-3 vikas engines is 55 tons compared to 40 tons for regular GSLV and PSLV rockets.

Technical details[edit]

The engine uses up about 40 metric tons of UDMH as fuel and Nitrogen tetroxide (N2O4) as oxidizer with a maximum thrust of 725 kN. An up-graded version of the engine has a chamber pressure of 58.5 bar as compared to 52.5 bar in the older version and produces a thrust of 800kN.
