The Indian Space Research Organisation, ISRO successfully tested the new liquid rocket engine manufactured through Additive Manufacturing technology. The test was successfully carried out on May 9th at ISRO Propulsion Complex in Mahendragiri in Tamilnadu. This new redesigned PS4 engine has brought down the number of parts from 14 to a single piece and eliminated 19 weld joints. This will significantly save on the raw material usage per engine, reduce metal powder from 565 kgs to 13.7 kgs and reduce the production time by 60 percent.

Akashvani Correspondent reports that this new redesigned engine will be used for the fourth stage of PSLV launch vehicle and also in the Reaction Control System of the First Stage in PSLV. ISRO is planning to induct this PS4 engine into the regular PSLV program. Additive Manufacturing technology means 3D printing of PS4 engines. The Private partner Wipro 3D joined hands with ISRO to successfully carry out the hot testing of the 3D printed PS4 engine. This will usher in a new era of advanced 3D manufacturing technique of India’s space programme.
