The Indian Space Research Organisation terminated the first hot test on an intermediate configuration of the semi-cryogenic engine following an unanticipated spike in the turbine pressure and subsequent loss of turbine speed.
The intermediate configuration of the semi-cryogenic engine is also known as a power head test article (PHTA).
The July 1 test at ISRO Propulsion Complex (IPRC), Mahendragiri, Tamil Nadu, was conducted towards developing a 2,000 kN (Kilonewton) thrust semi-cryogenic engine to power the booster stages of future launch vehicles, the Bengaluru-headquartered national space agency said in a statement on Monday.
