Rotor with offset

Abstract

A multi-planar rotor assembly for offset flapping hinges. In embodiments, the multi-planar rotor assembly includes an upper rotor disposed within a first vertical plane, and a lower rotor disposed within a second vertical plane vertically offset from the first vertical plane. A plurality of blade assemblies is coupled to the upper and lower rotors, with each blade assembly attached to a respective rotor via an offset flapping hinge positioned radially outward from a central rotational axis of the multi-planar rotor assembly. The upper and lower rotors are angularly offset relative to each other by a defined angular offset configured to establish a predetermined angular spacing between adjacent blade assemblies disposed across the first and second vertical planes. The multi-planar rotor assembly facilitates reduced flapping hinge offset distances, smaller rotor hub diameter, lower aerodynamic drag, reduced structural loads, improved maintenance access, and optimized control component clearances.
