Collaboration with Wipro 3D
The successful testing of the 3D printed PS4 engine was made possible through a collaborative effort between ISRO and private partner Wipro 3D. Leveraging their expertise in additive manufacturing, Wipro 3D worked closely with ISRO to conduct hot testing of the engine at the Mahendragiri facility in Tamil Nadu. This collaboration highlights the synergistic partnership between the government and the private sector in advancing space technology in India.
Redefining Rocket Design: Design for Additive Manufacturing (DFAM)
One of the key aspects of this achievement is the innovative redesign of the conventional PS4 engine to make it compatible with additive manufacturing technologies. ISRO implemented a process known as Design for Additive Manufacturing (DFAM), which involved reconfiguring the engine to reduce complexity and streamline production. The redesigned engine boasts a remarkable reduction in the number of parts, from 14 to a single piece, and eliminates 19 weld joints, leading to significant savings in raw material usage and production time.
Sustainable Innovation: Benefits of 3D Printing Technology
The adoption of 3D printing technology in rocket engine manufacturing offers several advantages, including enhanced efficiency, reduced waste, and improved sustainability. By drastically reducing the amount of metal powder required for production, from 565 kg to a mere 13.7 kg per engine, ISRO has achieved a remarkable 97 percent reduction in raw materials, contributing to a more eco-friendly manufacturing process. Additionally, the streamlined production process has resulted in a 60 percent reduction in production time, allowing for faster turnaround and cost savings.
Versatile Application: Integration into Launch Vehicles
The newly redesigned PS4 engine, which utilizes a bipropellant combination of nitrogen tetroxide as oxidizer and monomethyl hydrazine as fuel, holds immense potential for various applications in space missions. It is slated to be integrated into the fourth stage of the Polar Satellite Launch Vehicle (PSLV), enhancing the efficiency and performance of the launch vehicle. Furthermore, the engine will also be utilized in the reaction control system of the first stage of the PSLV, further showcasing its versatility and adaptability in diverse space missions.
Conclusion: Pioneering Innovation in Space Exploration
As ISRO continues to push the boundaries of space exploration and technology, the successful testing of the 3D printed liquid rocket engine 'PS4' represents a significant leap forward in rocket propulsion technology. This groundbreaking achievement not only demonstrates India's technological prowess but also underscores the nation's commitment to innovation and sustainability in space exploration. With this remarkable feat, ISRO sets a new benchmark for excellence in rocket propulsion technology, paving the way for future advancements and inspiring generations of scientists and engineers.
