BENGALURU: In an necessary step towards creating applied sciences for restoration of levels, resulting in reusability in future launch automobiles, Isro has efficiently demonstrated one other restart functionality of its Vikas liquid engine on Jan 17 on the Isro Propulsion Complex in Mahendragiri.
A workhorse engine that powers liquid levels of Isro rockets, Vikas’ restart know-how is prime to the restoration and reuse of rocket levels, a function that would considerably cut back the price of future house missions.

“A sequence of checks are being carried out to validate the restarting of the engine beneath totally different circumstances. In this (Jan 17) take a look at, the engine was fired for 60 seconds after which it was shut-off for a interval of 120 seconds adopted by restart and firing for 7 seconds period,” Isro mentioned.
All engine parameters through the take a look at have been regular and as anticipated. Previously, a shorter period restart was carried out efficiently in December 2024 with a shut-off time of 42 seconds and firing period of seven seconds every.
“Further checks are deliberate within the coming days to optimise the efficiency of the engine beneath restart circumstances,” Isro added.
In a separate improvement, the core liquid stage (L110) of Isro’s LVM-3 launch car was flagged off to the launch advanced at Sriharikota on Jan 17. This marks the tenth L110 liquid stage to be built-in at Isro Propulsion Complex, Mahendragiri.
The stage is designated for the LVM-3 mission that can launch the BlueBird Block 2 satellite tv for pc beneath a business settlement between NSIL and AST & Science, LLC.
The L110 stage, designed and developed by Isro’s Liquid Propulsion Systems Centre (LPSC) through the LVM-3 launch car’s improvement, options twin Vikas engines and carries 110 tonnes of propellant.
