Abstract: Example stands for supporting a component, such as a rotor blade, are described herein. An example stand described herein includes a blade support having an opening extending from an edge of the blade support towards a center of the blade support. The opening is to receive a rotor blade of an aircraft, for example. The example stand also includes a base to support the blade support above a supporting surface. The blade support is rotatably coupled to the base about a horizontal axis perpendicular to a central axis of the blade support such that the blade support can tilt the rotor blade relative to the supporting surface.

Abstract: An enclosure for carrying an adjustable payload. The enclosure is beneficially used on a rotorcraft blade or other similar structure. The enclosure has a first element having a first flange and an upper element. The first element has an upper surface which has a first angle with respect to a lower surface of the first flange in a direction extending from an inboard direction to an outboard direction. The upper element has a lower surface which has a second angle with respect to an upper surface of said upper element in a direction extending from an inboard direction to an outboard direction, the lower surface being in contact with the upper surface of said first element, the second angle being in a direction which is opposite to the direction of said first angle. The first element and the upper element define a cavity for holding a payload.

Abstract: A method and apparatus for reducing a vibratory response in a structure using a tuning object. A selected mass may be identified for the tuning object. A plurality of channels may be formed in a workpiece having a mass greater than the selected mass to form the tuning object having the selected mass. The tuning object may be bonded to the structure using an adhesive bond to reduce the vibratory response of the structure.
