Assembly
Ducommun AeroStructures supplies complex assemblies, sub-assemblies and kitting
for many of the world's aircraft manufacturers.
Our production engineering teams develop assembly tooling and fixtures for optimum
workflow and process efficiency. These fixtures and jigs are then built in-house
as part of program-specific work cells.
Spoilers. We use assembly jigs that we designed and assembled for both C-17 and
737 spoilers. These jigs were designed to minimize space since, for example, there
are 12 different spoilers on a 737. Composite Structures engineers designed the
jigs so a left and a right side are located on a single plate, saving space and
making for efficient workflow. During assembly we take the bonded component, do
close tolerance drilling to install bushings and bearings and then prep and paint.
An elaborate paint system is used for completing the assembly and preparing it for
install. We also assemble the framework for every 737 spoiler. This is made up of
end ribs and a leading edge channel that is riveted together in an assembly fixture.
Those details have been phosphoric acid anodized and primed and are being put together
in a clean room. Then they go to the bond tool and that's the start of the layup
for spoilers.
C-17 spoilers, add fairings, the bearings to titanium fittings, all done in assembly
jigs. We developed the entire system to meet the engineering requirements as part
of the IPT group with Boeing. Responsible for the design and build of the whole
string of tools - bond tools and assembly tools.
