ABSTRACT:
A blade retaining sub-assembly for use in a gas turbine engine which includes at least one radially extending blade mounted in a dovetail slot of a rotatable annular disk. The sub-assembly prevents the blade from migrating from the dovetail slot in an axially forward direction and includes a pair of circumferentially spaced lugs extending from a pair of adjacent disk posts such that each of the lugs are disposed axially forward of, and circumferentially adjacent to, respective ones of the lateral surfaces of the blade dovetail. The sub-assembly further includes a retainer plate disposed in each of the lugs and the plate restrained. The plate includes a body section and a contoured platform which is disposed in confronting relationship with the blade dovetail, wherein the contoured platform includes a periphery which is predeterminedly shaped and positioned so as to enhance a load carrying capability of the plate and lugs. The plate is restrained by a bracket attached to a spacer having an aft portion disposed in the dovetail slot inward of the blade, wherein the bracket includes a slotted mount hole which enhances a capability of the plate to flex about an axis which is generally parallel to a radially extending centerline passing through the hole.
