and frames for the A350 XWB -900
& -1000
• 100% of stringers and frames are
inspected using Orbital ATK’s
designed and patented NDI systems
Stringers and Frames
Orbital ATK is an industry leader in high-quality, automated composite manufacturing. A technology built for the next generation commercial aircraft, Orbital ATK’s patented automated stiffener forming machine (ASFM) provides lower cost, higher quality stiffeners, with superior compaction and repeatability compared to those produced using the previous industry-standard, hand lay-up process. Orbital ATK ASFM technology is also unique in the flexibility of its design. Providing both a linear and radial option, the ASFM can fabricate stringers and the frames, which make up the skeleton of a commercial aircraft fuselage shell, at production rates of nearly 10 times that of the traditional lay-up process.

Orbital ATK delivers affordable innovation that drives next-generation commercial engines. A world-leader in the design, development and production of automated processes for large diameter composite structures, Orbital ATK applies this expertise to the next-generation commercial aircraft engine market. Orbital ATK provides a light-weight option to traditional metal structures in the production of composite fan containment cases and composite aft cases as demonstrated on the GEnxTM and Rolls-Royce Trent XWB engines. The benefit of weight reduction provides greater fuel efficiency, increased payload capacity and extended range of the aircraft.
