1. A rotor mounting assembly for an aircraft comprising:
a boom configured for mounting to a wing of the aircraft;
a mount for mounting a rotor assembly, the mount connected to the boom at a joint and tiltable about the joint from a forward thrust orientation in which the rotor assembly can provide forward thrust to a vertical thrust orientation in which the rotor assembly can provide vertical thrust;
a multi-link assembly extending from the boom to the mount, the multi-link assembly comprising a crank arm fixed to the boom at a first connection point, a coupler arm fixed to the mount at a second connection point, and at least one section of airframe connecting the crank arm to the coupler arm through the joint, wherein the first connection point, the second connection point, and the joint do not align in the forward thrust orientation and do align in the vertical thrust orientation; and
an actuator for actuating the multi-link assembly to control tilting of the mount.
