Srinagar, Feb 01: Under the Technology Development Fund (TDF) scheme by DRDO, a Green Propulsion System showcased its successful in-orbit functionality via a payload launched during the PSLV C-58 mission.
The project, led by Bengaluru-based start-up Bellatrix Aerospace Pvt Ltd, introduced the 1N Class Green Monopropellant thruster for microsatellite altitude control and orbit maintenance.
Telemetry data from the PSLV Orbital Experimental Module (POEM) at ISRO Telemetry, Tracking, and Command Network (ISTRAC) in Bengaluru has been meticulously validated, surpassing all performance benchmarks.
This groundbreaking technology offers a non-toxic, environmentally friendly propulsion system tailored for low orbit space missions. The system comprises indigenous components such as Propellant, Fill and Drain Valves, Latch Valve, Solenoid Valve, Catalyst Bed, Drive Electronics, and more, making it ideal for missions with high thrust requirements
The comprehensive project, executed by Bellatrix Aerospace Pvt Ltd under the guidance of DRDO's Project Monitoring & Mentoring Group, successfully demonstrated pulsed mode and steady-state firing in a vacuum.
Noteworthy achievements include passivation of residual propellant in outer space, propellant realisation, and establishing a filling procedure under the TDF.
The Technology Development Fund, a Ministry of Defence flagship program executed by DRDO as part of the 'Make in India' initiative, plays a crucial role in funding innovation within the defence and aerospace sectors, particularly benefiting start-ups and MSMEs.
