The Vikas (a portmanteau from initials of VIKram Ambalal Sarabhai[5][6] ) is a family of hypergolic liquid fuelled rocket engines conceptualized and designed by the Liquid Propulsion Systems Centre in the 1970s.[7][8] The design was based on the licensed version of the Viking engine with the chemical pressurisation system.[9] The early production Vikas engines used some imported French components which were later replaced by domestically produced equivalents.[10] It is used in the Polar Satellite Launch Vehicle (PSLV), Geosynchronous Satellite Launch Vehicle (GSLV) and LVM3 for space launch use.
