The new liquid rocket engine manufactured through additive manufacturing technology by the Indian Space Research Organization (ISRO) successfully tested.
On 9 May, the test successfully conducted at ISRO Propulsion Complex in Mahendragiri, Tamil Nadu.
This newly redesigned PS4 engine has reduced the number of parts from 14 to one piece and eliminated 19 weld joints.
This will result in significant savings in raw material usage per engine, reducing metal powder from 565 kg to 13.7 kg and reducing production time by 60%.
This new, redesigned engine will be utilized in both the PSLV First Stage Reaction Control System and fourth stage of the PSLV launch vehicle.
ISRO is planning to include this PS4 engine in the regular PSLV programme.
Additive manufacturing technology means 3D printing of PS4 engines.
Private partner Wipro 3D and ISRO joined hands to successfully complete hot testing of 3D printed PS4 engine.
This will usher in a new era of advanced 3D manufacturing technology for India’s space programme.
