  • About VIKAS Engine:  It is an acronym for Vikram Ambalal Sarabhai. This engine belongs to the family of liquid-fuelled rocket engines, conceptualised and designed by the Liquid Propulsion Systems Centre (LPSC) of ISRO in the 1970s. 
  • Vikas Engine was invented by ISRO scientists including Nambi Narayanan who played a critical role. The design of this engine was in accordance with the Viking engine, a licensed version with chemical pressurization system.
  • The LPSC is a research and development centre functioning under ISRO. It is the centre for design, development and realisation of liquid propulsion stages for ISRO's launch vehicles.
  • LPSC activities and facilities are spread across its 2 campuses: LPSC Valiamala, Thiruvananthapuram and LPSC Bengaluru, Karnataka.
  • The early productions of for this engine involved imported French components, which were later replaced by domestically produced equivalents.
  • These engines are deployed for the ISRO's Polar Satellite Launch Vehicle (PSLV) and Geosynchronous Satellite Launch Vehicle (GSLV) series of expendable launch vehicles for space launch use.
  • The fuel load of the Vikas engine is 40 tonnes for the PSLV, GSLV Mark I and II and 55 times for the GSLV Mark III.
  • The Indian Space Research Organization has successfully tested the throttling of Vikas, its workhorse launch-vehicle engine.
