Further, as per the Indian space agency, during the test, the engine was successfully ignited and operated up to 60 per cent of its rated power level, demonstrating stable and controlled performance.

These tests are part of a planned series of evaluations designed to validate the design integrity and performance of critical subsystems, including the low-pressure and high-pressure turbo pumps, pre-burner and associated control systems, the statement added.

The results provided crucial data to finalise the operational sequencing of the full Semicryogenic engine.

Further qualification tests are scheduled to comprehensively validate the engine system, ultimately paving the way for its induction into ISRO's launch vehicles. (ANI)
