"fan produces 24 tonnes of thrust"....I greatly doubt it.
My reasons for stating this:
1) The fan aero system includes both the rotor AND stator vanes. The rotor creates some thrust, but the stator also creates thrust by converting dynamic pressure to static (by capturing and converting swirl energy). This stator portion of fan thrust has no connection to the thrust bearing.
2) The forward face of the LPT disc assembly is a large piston area with several atmospheres' worth of static pressure applied. (This is completely separate from forces acting on the airfoils.)
To what extent to you "greatly doubt it"?
For a high by-pass turbofan engine producing 30 tonnes of thrust overall at full power, what percentage of that thrust do you estimate is produced by the fan, the fan stators and jet efflux?
