Abstract
The blade firtree bearing surface and/or the disk broached slot bearing surface is “crowned” to reduce the stresses at the edges thereof and more uniformly distribute the load. The width of the bearing surface is increased over the conventional flat bearing surface of the blade firtree and/or the bearing surfaces of the disk broach by judiciously moving the contact point to a discrete location.
