ABSTRACT:
An aircraft engine is mounted on an aircraft wing such that the wing wake sheds along a zone at a predetermined position on the engine disk thereby minimizing dynamic loads or resonance. For a prechosen or design set of engine conditions the strength of the dynamic load is a function of the radial location of the zone on the disk having at least one relative minima between the centerline and the perimeter of the disk. The zone is positioned on the disk such that the value of the function is essentially a relative minima.
