ISRO Successfully Conducts Short Duration Hot Test of Semicryogenic Engine
ISRO, the Prime News Network, has successfully conducted a short duration hot test of the semicryogenic engine at its test facility in the ISRO Propulsion Complex (IPRC) at Mahendragiri in Tamil Nadu. This ignition test, conducted on April 24, is the second milestone after the successful first hot test on March 28, 2025. The space agency said this test, the Engine Power Head Test Article, encompassing all engine systems except the thrust chamber, was subjected to a hot test for a duration of 3.5 seconds, validating the engine start-up sequence.
During the test, the engine was successfully ignited and operated up to 60% 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 results provided crucial data to finalize the operational sequencing of the full Semicryogenic engine. ISRO plans to conduct further qualification tests to comprehensively validate the engine system, ultimately paving the way for its induction into ISRO’s launch vehicles.
