摘要： A method of making a pressure bulkhead assembly of an aircraft includes determining an optimized position of splice angles such that splice surfaces of the splice angles will form a circumferential splice surface of the pressure bulkhead assembly with an optimized shape. The method further includes performing a virtual fit between the plurality of splice angles, at the optimized position, and an aft pressure bulkhead. The method also includes determining splice-angle-hole positions of splice-angle holes to be drilled in each one of the splice angles such that the splice-angle holes will correspond to aft-pressure-bulkhead holes, pre-drilled in the aft pressure bulkhead. The method further includes drilling the splice-angle holes in each one of the splice angles at the splice-angle-hole positions. The method also includes joining each one of the splice angles with the aft pressure bulkhead such that the splice surfaces form the circumferential splice surface with the optimized shape.

摘要： Methods for using predictive shimming to optimize part-to-part alignment. In accordance with one embodiment, the process uses measurement data acquired from mating surfaces and key features to virtually align two parts in a manner that optimizes the final orientation of the parts and determines the geometry of the shim needed to achieve this orientation during assembly.

摘要： A manufacturing system includes a holding structure and actuators that are coupled to the holding structure. The actuators support the component and apply displacements to select locations of the component to change a current shape of the component toward a target shape of the component. The system includes a metrology system that takes measurements of the current shape of the component. The system includes a controller that utilizes a closed feedback loop to determine a deviation between the current shape and the target shape based on the measurements and to provide commands that iteratively change the displacements in response to changes in the current shape until the current shape is within a tolerance of the target shape.

摘要： A pressure bulkhead assembly for an aircraft includes an aft pressure bulkhead and a plurality of splice angles. The aft pressure bulkhead includes a bulkhead interface surface and aft-pressure-bulkhead holes, pre-drilled through the bulkhead interface surface. The plurality of splice angles is configured to be coupled to the aft pressure bulkhead. Each one of the plurality of splice angles includes a flange surface, configured to mate with the bulkhead interface surface. Each one of the plurality of splice angles also includes splice-angle holes, drilled through the flange surface. Each one of the plurality of splice angles further includes a splice surface, extending from the flange surface. With the splice-angle holes aligned with the aft-pressure-bulkhead holes, a plurality of splice surfaces forms a circumferential splice surface with an optimized shape.
