Bengaluru:The Indian Space Research Organisation (ISRO) 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 July 1 test at ISRO Propulsion Complex (IPRC), Mahendragiri, Tamil Nadu, was conducted towards developing a 2,000 kN (Kilonewton) thrust semi-cryogenic engine, known as power head test article (PHTA), to power the booster stages of future launch vehicles, the Bengaluru-headquartered national space agency said in a statement on Monday.
The objective of the test was to validate the integrated performance of the critical subsystems such as the gas generator, turbo pumps, pre-burner and control components by carrying out a hot-firing for a short duration of 4.5 seconds, it said. "The ignition and generation of hot gas within the pre-burner chamber that drives the main turbine to drive the fuel and oxidiser pumps were focussed," the statement from ISRO said.
