ATK to Produce Composite Fan Containment Cases for GEnx Engines

07 August 2006

Alliant Techsystems has received a multi-year, multi-million dollar contract from General Electric to produce fan composite containment cases for its GEnx engine.

The GEnx engine is designed to provide lower operating costs and greater fuel efficiency for the new Boeing 747-8. The five-year contract highlights ATK’s emerging role as a provider of large-scale composite components for aircraft engines.

The GEnx engine is the world's only jet engine that incorporates both a front fan composite containment case and composite fan blades. The new engine will reduce the aircraft’s weight, increase its payload capacity and extend its range.

“ATK is a world-leader in the design, development and production of automated processes for large-diameter composite structures,” said Ray Bronson, Vice President and General Manager, ATK Space Systems and Sensors. “We’re proud to be selected by GE, and we look forward to expanding our role in the commercial aerospace marketplace.”

The first ATK-fabricated GEnx fan composite containment case is scheduled for delivery in the spring of 2007. Design and production of the GEnx containment cases will begin immediately at ATK’s facilities in Clearfield, Utah.
