ISRO has successfully demonstrated the restart capability of its Vikas liquid engine at the Propulsion Complex in Mahendragiri. This milestone is a significant step toward advancing technologies for stage recovery, which could pave the way for reusability in future launch vehicles, potentially reducing the cost of space missions.
About the Vikas (Vikram Ambalal Sarabhai) Engine:
The Vikas engine was conceptualized and developed by ISRO’s Liquid Propulsion Systems Centre (LPSC), which is responsible for designing, developing, and realizing liquid propulsion stages for ISRO's launch vehicles. This engine is a crucial component, powering the liquid stages of several of ISRO’s launch vehicles and enhancing their payload capabilities.
PSLV (Polar Satellite Launch Vehicle):
The first Indian launch vehicle to feature liquid stages, the PSLV is a four-stage vehicle with the capability to launch multiple satellites into various orbits. The second and fourth stages are powered by liquid propulsion engines, with the second stage utilizing the Vikas engine, which runs on UDMH (Unsymmetrical Dimethyl Hydrazine) as fuel and Nitrogen Tetroxide (N2O4) as the oxidizer.GSLV (Geosynchronous Satellite Launch Vehicle):
A three-stage vehicle designed to launch communication satellites into geostationary transfer orbit, the GSLV features a cryogenic third stage. Its second stage is also powered by the Vikas engine.
