Some questions come to mind. If the IP disc self ejects, are we looking at a disc failure as the cause? Or is it more along the lines of the "Rigid Coupling" feature, which I am assuming is the disc's bearing mount on the shaft? Generally, with turbine engines things get heavier and more robust as the Rotating mass approaches its center, the shaft, itself.
since heavier and more massive assemblies cause more damage when they fail, how specifically is this incident impinging on this model's maintenance and service life ?
Also, my intuition is that Intermediate Turbine is the focus of high acceleration and pressure increase of the air mass, could excess bearing wear be caused by engineering insufficient to contain this stress? Also, could you explain the oft misunderstood difference between the Turbojet and the TurboFan?
Thanks, bear
