ISRO carries out demo of restarting Vikas liquid engine

The space agency said the Vikas liquid engine is the workhorse that powers the liquid stages of its launch vehicles.

The Indian Space Research Organisation (ISRO) has successfully carried out a demonstration of restarting its Vikas liquid engine at a test facility at Propulsion Complex in Mahendragiri, the space agency said on Saturday (January 18, 2025).

Revving Up Reusability: ISRO’s Vikas Engine Milestone

ISRO has achieved a major milestone with the successful demonstration of restarting the liquid engine. This marks a significant step towards developing reusable launch vehicle technologies. The test involved a sequence of firings and restarts, confirming the engine’s performance under varying conditions.

The Indian Space Research Organisation (ISRO) achieved a groundbreaking milestone with the successful demonstration of restarting its liquid engine. The test took place at the Propulsion Complex in Mahendragiri, setting a crucial foundation for future reusable launch vehicles.

The Vikas engine, pivotal to the liquid stages of ISRO’s launch vehicles, underwent a test on January 17 that included a sequence of firings. Initially, the engine was fired for 60 seconds, then shut off for 120 seconds, and restarted for a seven-second duration. All parameters were normal, paving the way for further advancements.

Plans are underway for additional tests to enhance the engine’s performance under restart conditions. In a related development, ISRO Chairperson V Narayanan oversaw the dispatch of the L110 stage of the LVM3, marking its tenth integration at the Mahendragiri complex for a commercial mission.
