Abstract

A rotor hub assembly includes an open rotor hub assembly with an open rotor hub and a mounting plate. The open rotor hub includes an annular base portion with periphery and a plurality of rotary member portions arranged about the annular base portion that each define an aperture for receiving a rotor blade. The mounting plate spans the annular base portion and is coupled to the annular base portion by a resilient member to accommodate radially expansion and contraction of the annular base portion according to loads exerted on the rotor hub by rotor blades seated in the apertures of the rotary member portions.
