Answer: ISRO
Notes: The Indian Space Research Organisation (ISRO) successfully conducted the first PreBurner Ignition trial for semi-cryogenic engine (SCE)-200 on May 2, 2024 at the semi-cryo integrated engine test facility (SIET) at IPRC, Mahendragiri. The pre-burner ignition test article (PITA) is a full complement of the engine power head system, excluding the turbopumps. The test proved that the pre-burner could ignite smoothly and continuously. The Vikram Sarabhai Space Centre (VSSC) created a start fuel ampule that combines triethylaluminium and triethyleboron to ignite the semi-cryogenic engine. This ampule was used for the first time in ISRO's 2000 kN semi-cryogenic engine.
