SCE-200 : 🇮🇳's First Semi-Cryogenic Engine

Updated: Jun 5, 2023


  • SCE-200 also known as Semi-Cryogenic Engine - 200 ( Tonne Thrust )

  • Developed by Liquid Propulsions Systems Centre ( LPSC ), Thiruvananthapuram, Kerala, India. ( Part of ISRO )

  • ISRO's 2000kN Semi-Cryogenic Engine will use Liquid Oxygen (LOX) and ISROSENE ( A Green propellant for use in future rocket & satellite propulsion systems, Basically rocket grade version of kerosene ) More About it Here:- ISROSENE LINK

  • It's an Oxidizer Rich Staged Combustion Cycle Engine that will be Used to Power ISRO's Future Medium and Heavy Lift Launch Vehicles, which help ISRO to deliver more payload into Space.

  • It will first Replace the 2 VIKAS Engines of the LVM3 Core Stage with 1 SCE-200 Engine. Even that New 1 Engine can Produce more thrust than the Previous 2 Engines. Which Help's in the Increase Payload Capacity of the LVM3 Launch Vehicle.

  • The engine however will not be the part of first flight of Gaganyaan, India's first manned mission to space given timelines and schedules

  • There are speculations that this engine will be used in ISRO's Future Next Generation Launch Vehicle (NGLV) Previously termed as Unified Launch Vehicle (ULV)

  • In 2009, the SCE-200 program was approved for ₹1798 crore (US$230 Million) and the program to develop a 2 MN class or 2000 kN Class main engine began

Test Stand Info:-

  • ISRO had a Newly Commissioned Semicryogenic Integrated Engine & Stage Test facility at the ISRO Propulsion Complex (IPRC), Mahendragiri.

  • The newly established test facility at IPRC, Mahendragiri, is capable of testing semi-cryogenic engines up to 2600 kN thrust and will support the subsequent testing and qualification of the fully integrated Semicryogenic engine and stage.
