Abstract
An integrally bladed rotor (IBR) includes a hub and blades, each blade includes an airfoil section extending from a blade root at the hub to a blade tip defining a radially outboard extent of the rotor blade to aerodynamically interact with a flow of air for compressing the air. A root fillet is integrally formed with the hub the airfoil section integrally extends therefrom. The blade includes a localized increased blade root thickness portion defined based on at least one of an axial thickness of a web portion of the hub and a chord length of the blade.
