ISRO successfully tests Cryogenic Engine (CE-20) for GSLV Mk-III / Chandrayaan-2 Mission Home / Archives/ ISRO tests Cryogenic Engine (CE-20) for GSLV Mk-III
The upper stage of GSLV MK-III vehicle is powered by Cryogenic Engine (CE)-20 which develops a nominal thrust of 186.36 kN with a specific impulse of 442 seconds in vacuum. The engine operates on gas generator cycle using LOX / LH2 propellants combination. The major subsystems of the engine are thrust chamber, gas generator, LOX and LH2 turbo pumps, igniters, thrust & mixture ratio control systems, Start-up system, control components and pyro valves. The fifth hardware of CE-20 integrated engine designated as E6 is earmarked for GSLV Mk-III M1-Chandrayaan 2 mission. The flight acceptance hot test of E6 engine was successfully tested for 25 seconds at High Altitude Test facility, ISRO Propulsion Complex (IPRC), Mahendragiri on October 11, 2018. The test demonstrated steady state operation of engine. The performance of all engine subsystems were observed to be normal during the hot test.
