Product: Wing flap for regional aircraft.
Radius proposed to Bombardier Aircraft a concept
for a new type of monolithic Outboard Flap structure
to replace an existing aluminum design. Following
a close collaboration with Bombardier design groups,
Radius proposed an RTM replacement for the multi-part
metal original. Radius provided design assistance,
tooling, manufacturing and process development,
and several first articles necessary for the certification
process. Radius also provided a number of materials
characterization panels and sub-elements to support
development and certification.
The RTM molding technique used
reduces the number of components by 95% (through
functional integration) and gives a very good
out-of-mold surface finish, so it is possible
to paint without labor-intensive surface filling
and preparation. The part is significantly lower
in cost than the metallic component.
Development started mid 2000.
The Flap is expected to be certified in late 2003.
