Abstract:
Systems and methods provide for edge protection and visual damage indication for a composite blade stringer. According to one aspect, an edge protection and visual indication system may be an edge treatment provided over an outer edge of a web of a composite blade stringer. The edge treatment may include a number of material layers encompassing the outer edge of the web and extending from a first surface of the web to a second surface of the web. The material layers may include a color contrasting layer and fiberglass layers. The material layers may alternatively include two overlapping, pre-cured angles.
Abstract:
An access door structure for a wing skin is received in an access hole opening which incorporates a protective glove having a set of mistake resisting features and engaging the periphery of the access hole opening. An inner door seals an interior of the access hole opening and has multiple fastener attachment elements and a set of mating mistake resisting features. An outer door engaged over an exterior of the access hole opening has fastener holes for mating alignment with the fastener attachment elements and receives a plurality of fasteners for engagement of the inner and outer doors.
Abstract:
A method of installing a door in an access opening in a skin of an aircraft. A composite inner door panel is positioned against an inside face of the skin. A composite outer door panel is positioned against an outside face of the skin. A plurality of fasteners is installed through fastener openings in the composite outer door panel. The plurality of fasteners is tightened to form a chamfered interface between the skin and the composite outer door panel.
