Abstract
A retractable rotor blade for a flying vehicle is configured to undergo extension and retraction movement and includes an interlink assembly, a helical ribbon assembly for reinforcing the interlink assembly, and a flexible and elastic sleeve configured to cover the interlink assembly and the helical ribbon assembly in the extended and retracted states of the rotor blade. The interlink assembly has 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. Each of the link base subassemblies has a damper configured to dampen movement of the interlink assembly during extension and retraction of the rotor blade.
