ISRO has successfully conducted two hot tests of the Gaganyaan Service Module Propulsion System (SMPS) at the space agency’s Propulsion Complex in Mahendragiri on July 3.The short-duration tests, lasting 30 seconds and 100 seconds respectively, were aimed at validating the test article configuration, ISRO said in a statement on Wednesday.
“The overall performance of the propulsion system during these hot tests was normal as per pre-test predictions. During the 100s test, simultaneous operation of all Reaction Control System (RCS) thrusters in different modes (steady state; pulsed) along with all Liquid Apogee Motor (LAM) engines was also successfully demonstrated.
“ISRO’s Liquid Propulsion System Centre (LPSC) is leading the technology development activities for the Gaganyaan SMPS. SMPS is a critical system of Gaganyaan Orbital Module and is required during orbital manoeuvring as well as specific abort scenarios,” the space agency said.
