A major milestone in the development of ISRO’s next generation launch vehicle, GSLV MkIII, was achieved on successful long duration hot test (635 seconds) of high thrust cryogenic engine (CE20) on 28-04-2015 at ISRO Propulsion Complex, Mahendragiri, Tamil Nadu. The CE20 cryogenic engine is being indigenously developed by ISRO to power the cryogenic stage of GSLV MkIII launch vehicle. The completion of successful long duration hot test has once again proved ISRO’s capability in mastering the complex cryogenic technology. All subsystems of this engine such as Thrust Chamber, Injector, Gas Generator, LOX & LH2 Turbopumps, Control Components, Pyro systems etc., and the ground Test Facility systems performed very well and the parameters are well within the prediction. A series of development tests on this engine are being carried out to validate the performance and to prove the design of the engine. Two cold start tests and four short duration hot tests were already carried out on this engine at IPRC, Mahendragiri.
