In an exciting development, the Indian Space Research Organisation (ISRO) and Wipro 3D have joined forces to revolutionize space technology. They have successfully manufactured the PS4 3D-printed rocket engine, which will power the fourth stage of the Polar Satellite Launch Vehicle (PSLV).
The PSLV is a remarkable expendable launch system that is specifically designed to place earth observation and scientific satellites into precise orbits. With its advanced navigation, guidance, and control systems, the PS4 stage ensures accurate orbital placement for a variety of applications such as remote sensing, oceanography, and disaster warning.
Traditionally, the PS4 engine was manufactured using conventional machining and welding techniques. However, in a groundbreaking move, Wipro 3D and ISRO decided to redesign it using additive manufacturing technology. This approach offers superior precision, reduces resource utilization, and significantly cuts down on material wastage and production time.
By utilizing Design for Additive Manufacturing and Laser Powder Bed Fusion technology, Wipro 3D and ISRO were able to consolidate the multiple and diversified components of the PS4 engine into a single unified production unit. This not only enhanced production efficiency but also improved the overall structural integrity of the engine.
The Director of Liquid Propulsion Systems Centre at ISRO, V Narayanan, expressed his excitement about the partnership, stating that Wipro 3D's expertise in additive manufacturing has been crucial in realizing their vision for sustainable space exploration. He also added that the successful integration of the 3D-printed PS4 engine into their mission is a significant milestone for ISRO and sets new standards for advanced manufacturing in the space industry.
Similarly, Yathiraj Kasal, the GM and Business Head of Wipro 3D, shared his enthusiasm for the project, highlighting the potential of advanced manufacturing in space. He also emphasized the partnership's contribution to ISRO's "Make in India" initiative and its promotion of domestic innovation and manufacturing. Kasal eagerly awaits the second round of testing to see the PS4 engine in action alongside ISRO.
After rigorous testing at the ISRO Propulsion Complex in Mahendragiri, the engine's performance was confirmed to meet the design safety and efficiency standards. The key performance metrics, including optimal chamber pressure, fuel management, combustion efficiency, and specific impulse, were all successfully tested under real-world conditions.
This partnership between ISRO and Wipro 3D is a prime example of the potential of advanced manufacturing in the space industry. It not only pushes the boundaries of innovation but also paves the way for more sustainable and efficient space exploration. We eagerly await the future developments of this collaboration and the exciting possibilities it brings.
