| PROPOSAL TITLE: | Affordable Composite Fan Containment Case with Integral Toughening Elements |
TECHNICAL ABSTRACT (LIMIT 200 WORDS)
The proposal program will develop and demonstrate an affordable
manufacruring approach to fabricate the latest generation of damage
tolerant composite fan case designs. These designs embed a grid of
stiffener ribs within the composite laminate to limit damage propagation
that is initiated during the fan blade containment event. This grid blunts
the crack growth and restricts damage within a "safe zone" that permits
structural viability of the case after the blade is contained. The
proposed work package will demonstrate that advanced braiding concepts can
be used to fabricate these composite-toughening elements in a cost-
effective manner. This economically viable fabrication method will allow
widespread application of the toughened design concept and enable weight
efficient, safe containment system designs for high bypass turbofan
engines.
POTENTIAL COMMERCIAL APPLICATIONS
Assuming that the technology is successfully demonstrated, this approach
can be applied to the design of all jet engine fan containment cases.
