SCE-200
Indian semi-cryogenic rocket engine / From Wikipedia, the free encyclopedia
Dear Wikiwand AI, let's keep it short by simply answering these key questions:
Can you list the top facts and stats about SCE-200?
Summarize this article for a 10 year old
The SCE-200 (also referred as Semi-Cryogenic Engine-200) is a 2 MN thrust class liquid rocket engine, being developed to power ISRO's existing LVM3 and upcoming heavy and super heavy-lift launch vehicles. It is being developed by Liquid Propulsion Systems Centre (LPSC) of ISRO and is expected to have first flight in 2020s.

Burning liquid oxygen (LOX) and RP-1 kerosene in an oxidizer-rich staged combustion cycle [5] , the engine will boost payload capacity of LVM3 replacing current L110 stage powered by 2 Vikas engines. It is also expected to power ISRO's upcoming Next Generation Launch Vehicle (NGLV)[6] rockets (previously planned as ULV) as well as ISRO's future reusable rockets based on RLV technology demonstrations.[7][8][9][10][11]
The engine in September 2019 reportedly had become ready to begin testing in Ukraine and enter service no earlier than 2022. The use of engine of India's first human spaceflight, hence was ruled out by ISRO. By November 2022, SCE-200 had neared completion of its qualification tests. Stage and development had been complete and a facility to test it at ISRO Propulsion Complex Mahendergiri was getting ready for ground tests.
