Abstract: A rotor blade assembly includes a rotor blade (504) comprising an inboard end (506) and an outboard end (508). A composite yoke fitting (502) made from a composite material is attached to the rotor blade (504). The composite yoke fitting (502) includes an outboard portion (510) inserted into the inboard end (506) of the rotor blade (504), an inboard portion (512), and a flexure region (514) about which the rotor blade (504) is configured to flex. The inboard portion (512) and the flexure region (514) are outside the rotor blade (504).

Abstract: The present invention includes a system and method for slowing the rotation of a rotor (902) using, for example, rotor brake system (900) for a rotorcraft (906) comprising: one or more generators connected to a main rotor gearbox (914); an electric distributed anti-torque system (924) mounted on a tail boom (108) of the rotorcraft comprising two or more electric motors connected to the one or more generators, wherein the two or more electric motors are connected to one or more blades; and wherein a rotation of the rotor is slowed by placing a drive load on the main rotor gearbox with the one or more generators to bleed the mechanical power from rotor into electrical power via the two or more electric motors, wherein the electric distributed anti-torque system generates thrust in opposing directions.
