Abstract: A cargo restraint that accommodates restraining ULDs having a distorted or elevated retention base is disclosed (e.g., a retention base that is spaced above a conveyor plane, for instance coinciding with a cargo deck). An outer pawl includes at least one pivot that is maintained in a fixed location on the outer pawl, and that is movable along a slot to change the elevation of the pivot (and the elevation of a restraining head of the outer pawl when in an erected position). Movement of the pivot along the slot first allows the restraining head of the outer pawl to be positioned above a retention base of a ULD, including when the retention base is at an elevated position. Further movement of the pivot along the slot allows the restraining head of the outer pawl to engage and move the retention base of the ULD toward/to the conveyor plane.

Abstract: A composite PDU tire in an aircraft cargo handling system may comprise a plurality of bonded regions configured to propel cargo within an aircraft cargo bay. The composite tire may include edge regions that are stiffer than a cylindrical region. The edge regions may be configured to have a greater wear resistance and abrasion resistance relative to the cylindrical region. The cylindrical region may be configured to have greater traction relative to the edge regions. The edge regions may include a fillet profile and may be configured to reduce chipping as cargo climbs across the tire.

Abstract: A releasable restraint may comprise a spline housing and a plunger removably coupled to the spline housing. A plurality of snap clips may be rotatably coupled to the plunger. The plurality of snap clips are configured to create an interference with the spline housing to limit movement of the plunger with respect to the spline housing. The plunger is configured to release from the spline housing in response to a pull force exceeding a predetermined threshold value.

Abstract: A cargo handling system (CHS) is provided and includes a guide tray along which an electric rail extends and a carrier movably disposable within the guide tray. The carrier includes a carrier surface, guide and contact rollers for establishing electric communication with the electric rail with the carrier movably disposed within the guide tray, drivable elements to assume retracted or extended positions at which, with the carrier movably disposed within the guide tray, the carrier surface is deployed within or above the guide tray, respectively; and a control system. The control system is configured to draw current from the electric communication between the electric rail and the contact roller and to use the current to operate the drivable elements to move the carrier along the guide tray and to control extension and retraction of the drivable elements.
