Abstract

An integrally bladed rotor (IBR) (201) includes a hub (210) and blades (220), each blade (220) includes an airfoil section (230) extending from a blade root (266) at the hub (210) to a blade tip defining a radially outboard extent of the rotor blade (220) to aerodynamically interact with a flow of air for compressing the air. A root fillet (240) is integrally formed with the hub (210) the airfoil section (230) integrally extends therefrom. The blade (220) includes a localized increased blade root thickness portion (256) defined based on at least one of an axial thickness (250) of a web portion of the hub (210) and a chord length (258) of the blade (220).
