Abstract
An integrally bladed rotor for an aircraft engine includes a hub and a circumferential array of blades extending from the hub. Each blade has an airfoil extending from a gaspath side of a platform provided at a periphery of the hub. The platform has a radial thickness T. An edge of the airfoil is disposed at an axial distance Lfrom an adjacent axial edge of the platform. A projection extends radially inwardly from an interior side of the platform opposite to the gaspath side. The projection has an axial thickness t, a radial height h from the interior side of the platform, and an axial distance Lfrom the adjacent axial edge of the platform. T is a radial thickness of the platform at an axial location of the projection, and
