ISRO achieved the major milestone with the successful hot testing of a liquid rocket engine manufactured through AM technology for a duration of 665 seconds on May 9, a release from the space agency said. The engine used is the PS4 engine of PSLV (Polar Satellite Launch Vehicle) upper stage.
The new engine, now a single piece, saves 97 per cent of raw materials and reduces production time by 60 per cent, ISRO said.
ISRO achieved the major milestone with the successful hot testing of a liquid rocket engine manufactured through AM technology for a duration of 665 seconds on May 9, a release from the space agency said.
The PS4 engine manufactured in the conventional machining and welding route has been in use for the fourth stage of PSLV which has a thrust of 7.33 kN in vacuum condition. The same engine is also used in the Reaction Control System (RCS) of the first stage (PS1) of PSLV, the release said.
The engine uses the earth-storable bipropellant combinations of Nitrogen Tetroxide as oxidiser and Mono Methyl Hydrazine as fuel in pressure-fed mode. It was developed by ISRO’s Liquid Propulsion Systems Centre (LPSC).
