Rotor with blades including outer blade shell and inner structural member

摘要

A rotor for use in an aircraft includes an inner hub; and a plurality of blades arranged around the inner hub, each of the plurality of blades comprising an inner structural member; an outer blade shell surrounding the inner structural member; and a centering block located at a base of the inner structural member proximal to the inner hub, wherein the centering block is located between a first lateral portion of the inner structural member and a second lateral portion of the inner structural member, wherein the centering block is further connected to the outer blade shell, and wherein the centering block allows the outer blade shell to rotate about an axis approximately corresponding to the inner structural member.

1. A rotor for use in an aircraft comprising:
an inner hub; and a plurality of blades arranged around the inner hub, each of the plurality of blades comprising:
an inner structural member;a structural outer blade shell surrounding the inner structural member;a centering block located at a base of the inner structural member proximal to the inner hub, wherein the centering block is located between a first lateral portion of the inner structural member and a second lateral portion of the inner structural member, wherein the centering block is further connected to the outer blade shell, wherein the centering block is connected to the outer blade shell by at least two bearings having a common axis of rotation, the base of the inner structural member fastened directly to the inner hub, andwherein the centering block allows the inboard portion of the structural outer blade shell to rotate about a single axis approximately corresponding to the inner structural member, an inboard portion of the outer blade shell rotatable about the single axis relative to both the centering block and the inboard portion of the base of the inner structural member proximal to the inner hub;wherein the first lateral portion of the inner structural member and the second lateral portion of the inner structural member extend from the base of the inner structural member and beyond the centering block in a direction towards an outboard end of the outer blade shell.
