Successful CE20 uprated Engine Hot Test with 21.8 T vacuum thrust The CE20 cryogenic engine indigenously developed for LVM3 has been subjected to a successful hot test at an uprated thrust level of 21.8 tonnes for the first time on November 9, 2022. This will enhance the LVM3 payload capability up to 450 kg with additional propellant loading.
The major modification carried out on this test article compared to previous engines was the introduction of a Thrust Control Valve (TCV) for thrust control. In addition to this 3D-printed LOX and LH2 turbine, exhaust casings were inducted into the engine for the first time.
During this test the engine operated with ~20 t thrust level for the first 40s, then the thrust level was increased to 21.8t by moving the thrust control valve. During the test, engine and facility performance was normal and the required parameters were achieved.
