ISRO successfully conducts hot test of CE20 cryogenic engine for LVM3 launch
ISRO scientists said this will enhance the LVM3 payload capability up to 450kg with additional propellant loading
The Indian Space Research Organisation (ISRO) successfully conducted the hot test of CE20 cryogenic engine
indigenously developed for LVM3 at an uprated thrust level of 21.8 tonne for the first time late on Wednesday night.
“The major modifications carried out on this test article compared to previous engines
was introduction of Thrust Control Valve (TCV) for thrust control. In addition to this 3D printed LOX and LH2 turbine exhaust casings
were inducted in the engine for the first time,” ISRO said on Thursday.
“During this test the engine operated with ~20t thrust level for first 40s, then thrust level was increased to 21.8t by moving thrust control valve.
During the test, engine and facility performance was normal and required parameters were achieved”, ISRO said.
HT had reported early November that ISRO is working to add to the weightlifting capacity of its heaviest rocket
Launch Vehicle Mark-3-- for its second launch scheduled early next year.
