Abstract: 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.

Abstract: 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.

Abstract: A seven day clock includes an open-face and a single hand rotatably mounted to, and generally centrally disposed on, the face. A motor driver rotates the hand at a uniform rate of rotation, about an axis of rotation, in a plane parallel to the face. The hand rotates in complete 360 degree revolutions about the face once every seven complete days. The face is demarked into seven contiguous equal sectors each bounded by two radii extending radially outwardly from the axis of rotation and labelled consecutively with the consecutive days of a week. The clock is adapted for a user to apply removable writing so that the writing overlays the face, and so that the removable writing is within the sectors.
