ISRO successfully tests new liquid rocket engine

• The new liquid rocket engine manufactured through additive manufacturing technology by the Indian Space Research Organization (ISRO) was successfully tested.

• The test was successfully conducted at ISRO Propulsion Complex in Mahendragiri, Tamil Nadu on 9 May.

• This redesigned PS4 engine has reduced the part count from 14 to one 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 used in both the PSLV first stage reaction control system and the fourth stage of the PSLV launch vehicle.
