Abstract

A retractable rotor blade assembly includes a rotor hub assembly having a rotor hub wall, a pitch disc mounted to the rotor hub wall for undergoing rotation about a longitudinal axis, and retractable rotor blades configured to be extended and retracted relative to the rotor hub assembly. Each of the rotor blades has an interlink assembly, a blade base, and a damper for dampening movement of the interlink assembly during extension and retraction of the rotor blade. The interlink assembly includes a plurality of interconnected link base subassemblies each configured to be translated along a span of the rotor blade such that each subsequent link base subassembly becomes stacked one atop the other while remaining connected to a next link base subassembly. The blade base is interconnected between the pitch disc of the rotor hub assembly and one of the interconnected link base subassemblies.
