Isro hot-tests CE-20 engine for GSLV-Mk3 to be used for next OneWeb launch | India News – Times of India


BENGALURU: The Indian Space Research Organisation (Isro) has successfully carried out the flight acceptance hot test of a CE-20 engine for a duration of 25 seconds in its high altitude test facility Mahendragiri.
The test happened on Friday. This engine is earmarked for the next GSLV-Mk3 mission — the LVM3-M3 — identified for the launch of the next set of 36 OneWeb India-1 satellites.
“The cryogenic upper stage of the LVM3 vehicle (C25 stage) is powered by a CE-20 engine working with the LOX-LH2 propellants combination. This engine develops a nominal thrust of 186.36 kN in vacuum,” Isro said.
The major objectives of the flight acceptance test were to confirm the integrity of hardware, assessment of subsystems’ performance and tune the engine for meeting mission requirements parameters for flight operation.
“Analysis of test data confirmed the satisfactory performance of the engine systems. This engine will be assembled to the C25 flight stage being integrated for the LVM3 M3 vehicle,” Isro added.
As reported by TOI earlier, the next OneWeb launch by Isro is through a commercial contract Space PSU NewSpace India Limited (NSIL) has with Bharti-backed OneWeb.
Earlier this week (October 23) Isro launched 36 OneWeb satellites onboard the GSLV-Mk3 — LVM3-M2 mission — as part of NSIL’s contract. The mission was GSLV-Mk3’s first commercial mission and India’s first attempt to launch a commercial satellite in a non-PSLV mission.
