Gaganyaan Mission: Major Service Module Propulsion System Testing Completed | India News – Times of India

Bengaluru: ISRO said on Thursday that it was successfully tested will be the same Service Module Propulsion System (SMPS) at the ISRO Propulsion Complex (IPRC) in Mahendragiri on Wednesday.
“The test consisted of five liquid apogee motors (Lam) engines with 440 N (Newtons) of thrust and 16 feedback control systems (rcs) thruster with a thrust of 100 N. The Service Module (SM) is a regulated bi-propellant based propulsion system that meets the requirements of the Orbital Module, performs orbit injection, circularization, on-orbit control, de-boost maneuver and performance. SM based abort (if any) during ascent phase,” ISRO said.
The LAM engines provide the main propulsive force during the mission’s ascent phase, while the RCS thrusters ensure precise attitude correction.
“The warm test of the System Demonstration Model (SDM) simulated the fluidic circuit of the SMPS, including propellant tank feed system, helium pressurization system, flight-worthy thrusters and control components,” ISRO said.
It added that the first hot test of the Phase-2 test series demonstrated the integrated performance of the Gaganyaan SMPS.
“The test, carried out for 250 seconds, consisted of firing the RCS thrusters as well as the LAM engines in continuous mode, following the test profile,” ISRO said.
As part of the Phase-I test series of the SM SDM, ISRO had previously conducted five hot tests, with a total duration of 2,750 seconds.
ISRO said, “The first stage consisted of five 440 N LAM engines and eight 100 N RCS thrusters. For the Stage-II test series, the current configuration includes the full configuration of five 440 N LAM engines and 16 100 N RCS thrusters.” “
The SMPS has been designed, developed and realized by the Liquid Propulsion Systems Center (LPSC).
“With the successful completion of this warm test, SMPS has moved forward in demonstrating its integrated performance in full configuration. Going forward, ISRO has scheduled five additional tests to demonstrate nominal and off-nominal mission scenarios , which reinforce the rigor of the test and the commitment to mission success.”
