Abstract: A gap measurement tool assembly for measuring a gap at a through hole between mating parts of a structure is provided. The assembly includes a gap measurement tool with a first end, a second end, and a body having a hollow inner channel, an exterior annular crevice, a first exterior annular groove having a cross-hole intersected by the hollow inner channel, and a second exterior annular groove. The assembly includes a first seal element, a second seal element, and a third seal element. The assembly is configured for insertion and sealing into the through hole, and the cross-hole is configured to align with the gap. When compressed air is passed into the gap, an air gage system takes a measurement of one of, a back pressure, an air flow, or a differential pressure, and correlates the measurement to a predetermined gap measurement, to determine a gap size of the gap.

Abstract: Methods and structures are disclosed. An example method includes: rotating a tubular mandrel about a longitudinal axis of the tubular mandrel; depositing a composite material on an inner surface of the tubular mandrel to form a composite tubular member on the inner surface of the tubular mandrel; inserting and expanding an inner expandable mandrel within the composite tubular member to cause the inner expandable mandrel to press the composite tubular member against the inner surface of the tubular mandrel; curing the composite tubular member; removing the inner expandable mandrel; placing a frame within the composite tubular member; and removing the tubular mandrel so as to obtain the composite tubular member with the frame placed therein.

Abstract: A method and apparatus for managing a configuration of a vehicle structure. Data sets are compared each representing the configuration of the vehicle structure at different phases in a lifecycle of the vehicle structure. Each of the data sets includes identifications of components for the vehicle structure. Differences are identified between the identifications of the components in the data sets.
