CE-20

Overview

Development and Testing

• On 28 April 2015, CE-20 cleared a 635 seconds long duration hot test at IPRC, Mahendragiri test facility. This test was preceded by two cold start tests and four short duration hot tests.
• On 16 July 2015, the first developmental CE-20 engine 'E1' was successfully endurance hot tested at ISRO Propulsion Complex, Mahendragiri for a duration of 800 seconds with Mixture Ratio Controller in closed loop mode. This duration is approximately 25% more than the engine burn duration in flight. This was tenth development test for CE-20
• On 10 August 2015, a short duration hot test on the CE20 engine was done to demonstrate the successful engine ignition with tank pressure conditions as in flight.
• On 19 February 2016, the second developmental CE-20 engine 'E2' was hot-tested for a duration of 640 seconds with Mixture Ratio Controller in closed loop mode at ISRO Propulsion Complex, Mahendragiri.
• On 03 December 2016, flight acceptance test of 25 seconds in high altitude conditions was carried out on third developmental CE-20 engine. It was successfully flown on the first developmental flight 'D1' of the GSLV Mk-III on 5 June 2017.
• On 25 January 2017, CE-20 engine E2 integrated with development stage for GSLV Mk III, C25 'D' was tested for duration of 50 seconds.
• On 17 February 2017, CE-20 engine E2 integrated with development stage for GSLV Mk III, C25 'D' was tested for duration of 640 seconds.
• On 11 October 2018, CE-20 engine E6 completed 25 second long flight acceptance test in high altitude conditions for GSLV Mk III M1/Chandrayaan-2 mission
