ISRO successfully conducted a short-duration hot test of the semicryogenic engine at the ISRO Propulsion Complex (IPRC) in Mahendragiri.
This test followed the first successful hot test on March 28, marking a significant milestone in the semicryogenic engine program.
The test involved the Engine Power Head Test Article, excluding the thrust chamber, and lasted 3.5 seconds.
The engine was ignited and operated at 60% of its rated power level, showing stable and controlled performance.
The tests aim to validate the engine's design, including critical subsystems like the turbo pumps and pre-burner.
The results will help finalize the operational sequencing of the full semicryogenic engine.
More qualification tests are planned before the engine can be integrated into ISRO's launch vehicles.
The launch activities for the NASA-ISRO Synthetic Aperture Radar (NISAR) satellite aboard the GSLV-F16 have already started in Sriharikota.
The Second Stage (GS2) of the GSLV was flagged off on March 24 for the NISAR mission.
