Abstract: A method of using a seal to seal a space between a first structure and a second structure that is movable relative to the first structure, the method includes engaging both the first structure and the second structure with the seal so as to seal the space with the second structure in a first position relative to the first structure, and disengaging the second structure from at least a portion of the seal with the second structure in a second position relative to the first structure so that at least a portion of the space is unsealed, where the second structure swipes across the seal moving between the first position and the second position.

Abstract: A seal is provided. The seal includes a seal panel having lateral sides. The seal also includes a seal locking mechanism coupled to the seal panel. The seal locking mechanism is configured to resiliently move, under impetus of an actuator, between an unbowed position of the seal locking mechanism and a bowed position of the seal locking mechanism.

Abstract: A seal for sealing a space between a first structure and second structure. The seal includes a seal base configured to couple with the first structure so as to form a respective seal with the first structure, a resilient lattice body coupled to the seal base, and a cover. The cover includes an inner surface coupled to the resilient lattice body in an opposing relationship relative to the seal base so that the cover moves towards and away from the seal base in a biasing direction of the resilient lattice body, and a bulbous outer surface configured to engage the second structure so as to form a respective seal with the second structure.

Abstract: A composite edge of an aircraft wing includes a composite wing box skin panel, attached to an outward wing spar in an attachment region, and a composite ramp, upon an outer surface of, and co-cured with, the composite wing box skin panel. The composite wing box skin panel has a proximal end and a distal end, with an overhanging edge, with substantially constant thickness and ply count in the attachment region. The composite ramp has a maximum ramp thickness at the distal end, the distal end being set back from the overhanging edge, defining a shoulder on the overhanging edge. A composite wing edge skin panel, having a thickness substantially equal to the maximum ramp thickness, is attached to the composite wing box skin panel at the shoulder and adjacent to the distal end of the ramp.

Abstract: A composite edge of an aircraft wing includes a composite wing box skin panel, attached to an outward wing spar in an attachment region, and a composite ramp, upon an outer surface of the composite wing box skin panel. The composite wing box skin panel has a proximal end and a distal end, with an overhanging edge, with substantially constant thickness and ply count in the attachment region, the overhanging edge being without any joggle. The composite ramp has a maximum ramp thickness at the distal end, the distal end being set back from the overhanging edge, defining a shoulder, having a relief radius, on the overhanging edge. A composite wing edge skin panel, having a thickness substantially equal to the maximum ramp thickness, is attached to the composite wing box skin panel at the shoulder and adjacent to the distal end of the ramp.

Abstract: Aircraft trailing edge devices, including devices having forwardly positioned hinge lines, and associated methods are disclosed. An aircraft system in accordance with one embodiment of the invention includes a wing and a trailing edge device coupled to the wing. The trailing edge device can be movable relative to the wing between a stowed position and a deployed position, with the trailing edge device having a leading edge, a trailing edge, an upper surface, and a lower surface. The upper surface can have an intersection point with the wing when the trailing edge device is in the stowed position. The motion of the trailing edge device relative to the wing can include rotational motion about a hinge line positioned forward of the intersection point, and a gap can be positioned between the trailing edge of the wing and the leading edge of the trailing edge device when the trailing edge device is in the deployed position.

Abstract: A multi-section aircraft door includes a sliding joint permitting a lower door section displacement into the flight deck area. The door includes an upper door section having a lower edge. The lower edge is connectably joined to an upper member of a two-member sliding joint. The upper member slidably joins to a sliding joint lower member. The sliding joint lower member is connectably joined to a lower door section upper edge. The upper member and the lower member of the two-member sliding joint include paired apertured embossments. A frangible pin slidably mates in each apertured embossment pair. A lever and cam form a frangible pin removal assembly. The lever is held in a normally upright position by either a spring device or a clevis and pin assembly. A rotating clasp or a ball détente system can also replace the frangible pin/apertured embossment and cam/lever.

Abstract: A flight deck door for an aircraft that is both ballistic resistant and intruder proof. The flight deck door includes a laminated ballistic resistant material which can also provide intruder resistant properties. The ballistic resistant or armor material can be laminated onto a core to provide additional rigidity to the flight deck door. The core also increases the rigidity of the flight deck door and increases intruder resistance. Also sound dampening layers may be added to the door.
