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.
