Inventors:

- Providence RI, US
John McCullough - Weatherford TX, US
Russell Steven Cole - Euless TX, US
Zachary Edwin Dailey - Grapevine TX, US

International Classification:

B64C 27/48
B29C 70/54

Abstract:

A rotorcraft main rotor system, including a yoke, a rotor blade, and a grip assembly attaching the rotor blade to the yoke. The grip assembly includes a grip body formed from a contiguous laminated composite and has a substantially constant thickness, where the grip body has an upper extension, a lower extension and a connecting portion connected between an inboard end of the upper extension and an inboard end of the lower extension. An inside surface of the upper extension faces, and is substantially parallel to, an inside surface of the lower extension, and the upper extension has first features and the lower extension has second features that are aligned with the first features, where the first features and second features each include at least one of an edge contour, attachment holes, or first protective elements.
