ISRO conducted the first ignition trial for SCE-200 (semi-cryogenic engine-200) at the semi-cryo integrated engine test facility (SIET) in Mahendragiri.
Semi-cryogenic engine ignition is achieved using a start fuel ampule which uses a combination of Triethylaluminium and Triethyleboron.
This is used for the first time in ISRO in the 2000 kN semi-cryogenic engine.
The SCE-200 is a 2MN thrust class liquid rocket engine developed by ISRO’s Liquid Propulsion Systems Centre (LPSC).
This next generation rocket engine is designed to enhance the payload capability of ISRO’s Launch Vehicle Mark-III launcher and other future launch vehicles.
