Abstract:
A system for displaying guidance aids to a crew for ground obstacle avoidance, particularly wingtip clearance. Perspective areas are drawn representing the current locations of the wingtips over the ground and predicted locations out into the future for a specified time or a specified distance. A flight crew may use these displayed guidance aids to determine the proximity of any perceived threat to the airplane. This capability addresses the costly problem of wingtip/airplane ground collisions. The disclosed graphical cue systems are specifically targeted toward aircraft that have a large wing span/size and/or folding wingtips.

Abstract:
A coating includes at least one coating layer containing first particles, second particles, and third particles distributed throughout a cross-linked, continuous polymer matrix. An outer surface of the coating layer includes surfaces of at least first particles extending outward from a top periphery of the polymer matrix. The outer surface exhibits a property of delaying ice formation compared to the coating layer without the first particles. A method includes applying a coating composition in one application step. The one-step coating composition contains first particles, second particles, and third particles in a base containing a polymer. A coating composition includes first particles, second particles, and third particles distributed in a matrix precursor.
Abstract:
A system (100) is provided for access to system-related resources for complex-system parts. The system (100) includes a barcode reader (202) and front-end engine (204) coupled thereto. The barcode reader (202) is configured to scan a barcode located on a complex-system part. The barcode encodes links to respective system-related resources for the complex-system part, including software-based systems and/or electronic documents. The barcode reader (202), then, is configured to decode the links from the barcode. The front-end engine (204) is in turn configured to generate a portal that identifies the complex-system part, and that includes the links decoded from the barcode. The front-end engine (204) is also configured to cause display of the portal in a graphical user interface through which the links are navigable to access the respective system-related resources for the complex-system part.
Abstract:
A gas separation module includes at least one inlet port, a plurality of outlet ports, and a plurality of hollow fiber membranes. Individual fibers have a feed end and a product end with a retentate interior side and a permeate exterior side. The module includes a feed tubesheet within the shell segregating the at least one inlet port and the permeate side of the fibers. The feed tubesheet includes a matrix and at least one segment joint. The segment joint separates segments of the feed tubesheet from one another. A formation method includes positioning a hollow fiber membrane material in association with at least one tubesheet segment joint and applying a matrix. The method includes forming a feed tubesheet from cured matrix and the segment joint and forming a plurality of hollow fiber membranes from the fiber material. The segment joint separates segments of the feed tubesheet from one another.
Abstract:
A method and apparatus for managing parts. Location information is displayed for a part on an aircraft on a mobile device. A determination is made as to whether the part is present in a location using a sensor system in the mobile device when the mobile device is in a zone including the location. A presence of the part in the location is indicated in response to the part being present in the location.
Abstract:
Interlaminar features of a composite structure are laid up by placing and steering individual chopped fiber pre-preg segments onto a substrate.
Abstract:
Two composite carbon fibre laminates (24, 26) are joined together by a bondline (22) having portions exposed to the ambient environment. The bondline contains scrim (32) embeded in adhesive layers (34, 36) having an electrical conductivity and impedance matched to that of the laminates in order to mitigate effects of lightning strikes.
