A landing gear door system for a landing gear compartment includes a door pivotable about a pivot pin configured for disposition in a longitudinal direction on an airframe, and a mechanism configured to rotate the door about the pivot pin between a closed position, in which an outer surface of the door panel is configured to provide aerodynamic continuity with an outer aircraft skin of the airframe, and an open position, in which the door is rotated into the landing gear compartment and an opening is exposed. The door has a door panel rigidly connected with an arm such that the door panel and arm generally form a V-shape as viewed in the longitudinal direction.
Composite Structural Panels And Methods Of Forming Thereof
Described are novel composite structural panels and methods of forming such panels. In some examples, a method comprises wrapping a mandrel with a composite tape to form a composite tube. This wrapping operation allows forming composite tubular structures with any cross-sectional profiles defined by the mandrel. The wrapping is also used to control the fiber orientations in the composite tubular structures. The composite tube is then cut into composite tubular structures. In some examples, the composite tube is partially cured prior to the cutting, which allows removal of the mandrel while preserving the shape of the composite tube. This cutting operation allows forming composite tubular structures with different lengths, shapes, and orientations of the ends. The composite tubular structures are disposed on a support structure and are bonded to each other. In some examples, this bonding operation also involves final curing of the composite tubular structures.

F16B 31/02
Abstract:
A load-indicating washer for use with a fastener. The washer is comprised of a circular base plate, a domed cap that projects from the base plate, a cavity formed between the circular base plate and the domed cap, and a fastener hole that extends through the circular base plate and the domed cap. The domed cap is configured to collapse into the cavity upon application of a force that exceeds a threshold.
