The Indian Space Research Organisation terminated the primary sizzling test on an intermediate configuration of the semi-cryogenic engine following an unanticipated spike in the turbine pressure and subsequent lack of turbine speed.
The intermediate configuration of the semi-cryogenic engine is also called an influence head test article (PHTA).
The July 1 test at ISRO Propulsion Complex (IPRC), Mahendragiri, Tamil Nadu, was carried out in the direction of creating a 2,000 kN (Kilonewton) thrust semi-cryogenic engine to energy the booster levels of future launch autos, the Bengaluru-headquartered nationwide area company stated in a press release on Monday.
The goal of the test was to validate the built-in efficiency of the essential subsystems such because the gasoline generator, turbo pumps, pre-burner and management parts by finishing up a hot-firing for a brief length of 4.5 seconds, it stated.

“The ignition and generation of hot gas within the pre-burner chamber that drives the main turbine to drive the fuel and oxidiser pumps was focussed,” the assertion from ISRO stated.
“The test proceeded as predicted till 1.9 seconds validating the ignition and subsequent performance of PHTA. At 2.0 seconds, an unanticipated spike in the turbine pressure and subsequent loss of turbine speed was observed. As a precautionary step, the test was terminated. Analysis under progress would offer further understanding before proceeding with further hot tests for longer duration,” the assertion stated.
The semi-cryogenic engine utilises a propellant mixture of liquid oxygen and kerosene, and the PHTA kinds the primary {hardware} test of the engine growth programme.
The test was carried out on the devoted test facility just lately established at IPRC for testing semi-cryogenic engines and levels.
ISRO had commenced the testing of PHTA in May at this facility.
