ISRO and Wipro 3D Partner on 3D-Printed PS4 Rocket Engine for PSLV
Bengaluru: The Indian Space Research Organisation (ISRO) and Wipro 3D announced a significant partnership in space technology on Friday, unveiling the successful manufacturing of the PS4 3D-printed rocket engine for the fourth stage of the Polar Satellite Launch Vehicle (PSLV).
The PSLV is a vital launch system designed for precise orbital placement of earth observation and scientific satellites, facilitating applications such as remote sensing, oceanography, and disaster warning.
The PS4 stage is equipped with advanced navigation, guidance, and control systems to ensure accurate orbital deployment. Its versatility for various spacecraft missions is enhanced by multiple restart capabilities and payload adaptability.
Traditionally manufactured through conventional methods involving machining and welding, the PS4 engine underwent a transformative redesign using additive manufacturing technology. This approach offers superior precision, minimal resource utilization, and significant reductions in material wastage and production time.
Wipro 3D and ISRO employed Design for Additive Manufacturing (DfAM) and Laser Powder Bed Fusion (LPBF) technology to consolidate diverse PS4 engine components into a unified production unit, enhancing efficiency and structural integrity.
Dr. V Narayanan, Director of the Liquid Propulsion Systems Centre (LPSC) at ISRO, highlighted, “Wipro 3D’s expertise in Additive Manufacturing has been pivotal in realizing our vision for sustainable space exploration. Integrating the 3D-printed PS4 engine into our mission is a significant milestone for ISRO, setting new standards in advanced manufacturing for the space industry.”
Yathiraj Kasal, GM and Business Head of Wipro 3D, added, “We are honored to collaborate with ISRO on this pioneering project, advancing ISRO’s ‘Make in India’ initiative and fostering domestic innovation. Manufacturing the PS4 engine for the PSLV vehicle underscores our commitment to space excellence.”
The 3D-printed PS4 engine features intricate cooling channels, emphasizing sustainability and operational efficiency with reduced material waste and machining needs.
Extensive testing at ISRO’s Propulsion Complex in Mahendragiri validated the engine’s performance under real-world conditions, meeting stringent safety and efficiency standards. Key performance metrics, including optimal chamber pressure, fuel management, combustion efficiency, and specific impulse (Isp), were successfully demonstrated during extended duration tests.
