Rotating structure and a method of producing the rotating structure

A rotating structure, comprising:

• a turbomachine hub having a plurality of mounting slots each defined by a cavity surface;
• a plurality of rotatable fan blades each having an anchor structure disposed in an associated one of the mounting slots;
• and
• at least one wear member disposed between each anchor structure and the cavity surface defined by the associated mounting slot,
• wherein each wear member includes at least two materials having different moduli of elasticity and disposed in discrete portions of the wear member.

A method of producing a rotating structure having a rotatable member and a rotatable hub wherein an anchor member of the rotatable member is adapted for retention by surfaces defining a slot in the hub, the method comprising the steps of:

• determining stresses experienced by first and second anchor structure portions as a result of the hub rotating the rotatable member;
• providing a wear member including first and second wear member portions having different wear characteristics that are dependent upon the stresses;
• and
• assembling the anchor structure and the wear member in the slot so that the wear member is disposed between the anchor structure and the surfaces defining the slot and so that the first and second wear member portions are disposed adjacent the first and second anchor structure portions, respectively.
