ISRO successfully conducts ground test of high thrust version of Vikas Engine
ISRO has successfully conducted ground test of its high thrust version of Vikas Engine at ISRO Propulsion Complex (IPRC) in Mahendragiri, Tirunelveli district of Tamil Nadu for duration of 195 seconds. The tests meet all its propulsion parameters and were found satisfactory and closely matched the predictions.
Vikas belongs to family of liquid fuelled rocket engines conceptualized and designed by ISRO’s Liquid Propulsion Systems Centre in the 1970s. The design was based on licensed version of Viking engine with chemical pressurisation system. It is the workhorse liquid rocket engine powering second stage of India’s Polar Satellite Launch Vehicle (PSLV), second stage and four strap on stages of Geosynchronous Launch Vehicle (GSLV) and is part of first stage i.e. twin engine core liquid stage (L110) of GSLV Mk-III. The propellant loading for Vikas engine in PSLV, GSLV Mark I and II is 40 tons, while in GSLV Mark III it is 55 tons. The recently tested high thrust version of Vikas engine will improve payload capability of PSLV, GSLV and GSLV Mk-III launch vehicles.
