NEWS – ISRO tests Additive Manufacturing (AM) Liquid Rocket Engine

HIGHLIGHTS

• Hot Test Success:
  • Isro hot-tested a liquid rocket engine designed through additive manufacturing (AM) technology.
  • Conducted at the Iaro Propulsion Complex in Mahendragiri, Tamil Nadu, the test validated key performance parameters of the redesigned PS4 engine.
• Additive Manufacturing (AM) Technology:
  • AM involves depositing materials layer by layer to create 3D objects.
  • The conventionally manufactured PS4 engine is used in the fourth stage of the Polar Satellite Launch Vehicle (PSLV) and the Reaction Control System of PSLV’s first stage (PS1).
• Redesign Benefits:
  • Isro’s Liquid Propulsion Systems Centre (LPSC) redesigned the engine using the Design for Additive Manufacturing concept.
  • Advantages include reducing parts from 14 to a single piece, eliminating 19 weld joints, saving raw material usage, and reducing production time by 60%.
• Manufacturing Partner:
  • Wipro 3D was involved in the manufacturing of the engine using additive manufacturing technology.
