ISRO successfully tests Gaganyaan Service Module Propulsion System

The Hindu  

Indian Space Research Organisation successfully tested the Gaganyaan Service Module Propulsion System at ISRO Propulsion Complex in Mahendragiri, Tamil Nadu, on July 19. This test involved five liquid apogee motor engines with a thrust of 440 N, and 16 reaction control system thrusters with a thrust of 100 N. The service module of Gaganyaan is a regulated bi-propellant based propulsion system that caters to the requirements of the Orbital Module, performing orbit injection, circularisation, on-orbit control, de-boost manoeuvring, and SM-based abort during the ascent phase. The hot test of the System Demonstration Model emulated the fluid circuit of the Service Module Propulsion System, encompassing the propellant tank feed system, helium pressurisation system, flight-qualified thrusters, and control components. The first hot test of the Phase-2 test series demonstrated the integrated performance of the Gaganyaan Service Module Propulsion System.
