Assembly of complex multi-component titanium/inconel structure
|
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.
One example of our assembly capabilities are aircraft 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. Ducommun AeroStructures 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.

In the process of building C-17 spoilers, we add fairings, plus the bearings to titanium fittings, and all work is completed in assembly
jigs. We developed the entire system to meet the engineering requirements as part
of the IPT group with Boeing. We are responsible for the design and build of the whole
string of tools - bond tools and assembly tools.
Foam Matrix Core SystemTM Technologies
Many assemblies can benefit from our innovative FMC SystemTM processes. An important element of these patented technologies is design-for-integration. The FMC System results in lower part count and fewer manufacturing labor hours. When compared to conventional designs such as a bolted or secondarily bonded wing, for example, a Foam Matrix Core SystemTM design relies on structural foam cores that provide integrity and support primary load path among integral fiber reinforced components. Fewer parts and the elimination of secondary bonding or
