Its ground test with an increased thrust of 27.6%, and 47% of increase for its high altitude test.
Even the eventual thrust of the deployed engine will be smaller than during its test stage, just like the GE9X had the thrust of 61 tonnes during its engineering test, but its actual thrust on the Boeing 777X is 50 tonnes.
China's VCE has achieved a maximum afterburner thrust of 270 KN during its high altitude test, but its actual maximum thrust after being deployed on the J-36/J-50 can still easily exceed 200 KN.
