The Indian Space Research Organisation (ISRO) has achieved a significant breakthrough by conducting a successful long-duration test of its PS4 engine, which was redesigned for production using advanced additive manufacturing (AM) techniques, commonly known as 3D printing. This marks a major milestone in India’s space exploration endeavors.
Key Points:
– ISRO conducted a long-duration test of the PS4 engine, redesigned for production using cutting-edge additive manufacturing techniques.
– The new single-piece engine saves 97% of raw materials and reduces production time by 60%.
– The engine underwent successful hot testing for a duration of 665 seconds on May 9.
Details:
– The PS4 engine, utilized in the fourth stage of the Polar Satellite Launch Vehicle (PSLV), was manufactured through AM technology, significantly enhancing efficiency and reducing resource consumption.
– Previously manufactured through conventional machining and welding methods, the engine has now been redesigned as a single piece, eliminating the need for 14 separate parts and 19 weld joints.
– The Laser Powder Bed Fusion technique employed in the manufacturing process has led to substantial savings in raw material usage and production time.
– Developed by ISRO’s Liquid Propulsion Systems Centre (LPSC), the engine utilizes earth-storable bipropellant combinations and was hot tested at ISRO Propulsion Complex, Mahendragiri, Tamil Nadu.
– Detailed simulations and testing were conducted to ensure the engine’s performance parameters met expectations.
Following successful testing, ISRO plans to integrate the AM PS4 engine into its regular PSLV program, marking a significant advancement in India’s space technology capabilities.
The successful testing of the 3D-printed rocket engine underscores ISRO’s commitment to innovation and signifies a leap forward in India’s space exploration endeavors.
