ISRO and Wipro 3D Forge New Frontier in Space Technology
In a groundbreaking collaboration, the Indian Space Research Organisation (ISRO) and Wipro 3D have joined forces to propel space exploration into a new era. Their partnership has yielded the successful creation of the PS4 3D-printed rocket engine, a marvel of innovation that powers the fourth stage of the Polar Satellite Launch Vehicle (PSLV).
The PSLV, renowned for its precision in placing earth observation and scientific satellites into orbit, serves a multitude of vital functions such as remote sensing, oceanography, cartography, mineral mapping, and disaster warning systems.
Traditionally, the PS4 engine was crafted through conventional machining and welding techniques. However, the collaboration between ISRO and Wipro 3D has revolutionized this process by employing additive manufacturing technology. This cutting-edge approach not only enhances precision but also minimizes resource consumption, reduces material wastage, and significantly slashes production time.
Through the adoption of Design for Additive Manufacturing (DfAM) and Laser Powder Bed Fusion (LPBF) technology, the intricate components of the PS4 engine have been consolidated into a single, unified unit. This consolidation not only streamlines production but also reinforces structural integrity, ensuring reliability and performance under the demanding conditions of space.
Dr. V Narayanan, Director of the Liquid Propulsion Systems Centre (LPSC) at ISRO, expressed his enthusiasm for the project, hailing it as a significant milestone for ISRO and a testament to the transformative power of advanced manufacturing in space exploration. The partnership not only advances ISRO’s 'Make in India’ initiative but also fosters domestic innovation and manufacturing capabilities.
Yathiraj Kasal, GM and Business Head at Wipro 3D, echoed Dr. Narayanan's sentiments, emphasizing the honor and privilege of contributing to such a pioneering endeavor. The 3D-printed PS4 engine, with its integral complex cooling channels, exemplifies sustainability and efficiency, embodying a commitment to minimizing material wastage and post-print machining operations.
Rigorous testing conducted at the ISRO Propulsion Complex in Mahendragiri has validated the engine's performance under real-world conditions, confirming its adherence to design safety and efficiency standards. Key performance metrics, including optimal chamber pressure, fuel management, combustion efficiency, and specific impulse (Isp), have all met or exceeded expectations.
As ISRO and Wipro 3D await the successful second round of testing, anticipation runs high for the PS4 engine's inaugural flight alongside the PSLV. This collaboration not only propels India's space exploration endeavors to new heights but also sets a precedent for advanced manufacturing in the global space industry.
