Abstract

A rotor assembly includes a rotor hub which rotates about a hub rotation axis and a blade connected to the rotor hub. The blade rotates with the rotor hub around the hub rotation axis, and the blade is configured to rotate around a pitch rotation axis of the blade to adjust a pitch of the blade. The rotor assembly includes a pitch horn having a first end rotatably connected to the blade. The pitch horn is configured to rotate with the blade around the pitch rotation axis of the blade to adjust the pitch of the blade, and the pitch horn is configured to rotate relative to the blade around a pitch horn pivot axis arranged at a non-parallel angle relative to the pitch rotation axis of the blade.
