Abstract: A method is provided for remanufacturing a machine component having multiple holes. The holes are provided to match in alignment with corresponding holes of an adjacent component in a machine assembly. First and second sets of holes are selected from the holes of the machine component on the basis of being located within first and second limits of positional tolerance with respect to corresponding holes of the adjacent component. Each hole from the first set of holes is bored to define openings in axial alignment with holes of the adjacent component. Each hole from the second set of holes is bored to an enlarged diameter and then plugged with a deformable insert. Each of these inserts is then drilled to define openings in axial alignment with holes of the adjacent component.

Abstract: Systems and methods for reducing wind pressure on wind turbine blades by selectively opening excessive wind portals in the turbine blades. One embodiment comprises a wind turbine system in which each of the turbine's blades has a portal therethrough that is opened or closed by a movable panel. Each panel is connected on one edge to the corresponding blade at the edge of the portal. Hook-and-loop material (Velcro) is attached to the edges of each portal and panel, allowing the panels to alternately open and then close the portals over a series of high wind events. Excessive wind pressure forces the panels to be released, opening the portals. Gravity or reversed wind direction with respect to the blade can be used to reseal the panels.
