A hover-capable aircraft includes a body including a tubular strut, a first rotor assembly rotatably coupled to the body and positioned about the strut, wherein the first rotor assembly includes a first plurality of circumferentially-spaced blades, a first actuation assembly including a first plurality of electronically controlled actuators coupled to a first swashplate and configured to control the movement of the first swashplate relative to the body, and a control system coupled to the body and configured to control the first plurality of actuators, wherein the control system includes a cable extending through a passage formed in the tubular strut and in signal communication with the first plurality of actuators.

Hover-capable aircraft

A method and device provide a rotorcraft operator with real-time information concerning acoustic radiation on a region of the ground in the vicinity of the rotorcraft. A noise radiation model and at least one measured flight variable determine a high noise region on the ground that is bounded by a predefined noise level threshold. The method/device may include a display showing the high noise region and the position of the rotorcraft on a map. The rotorcraft operator may also be provided with real-time Blade-Vortex Interaction ('BVI') avoidance guidance while the rotorcraft is in flight.
