November 20, 2010 - ITT Corporation has delivered its first major structural subassemblies for the CH-53K heavy lift helicopter to Sikorsky Aircraft Corporation. This delivery culminates nearly three years of advanced design, development, testing and manufacturing to provide sponsors for the CH-53K helicopter. These assemblies represent significant technology advancement by applying composite materials versus traditional metals to military aircraft that operate in harsh environments. Sponsors attach to each side of a helicopter fuselage and house important components, such as landing gear, fuel, and other mechanical and electrical assemblies without compromising interior passenger or cargo space. Each sponsor is 25 feet long by 4 feet wide and 5 feet high. |

This
delivery supports the first prototype aircraft, with future
potential to support 200 aircraft during the life of the
program. The CH-53K helicopter program is using proven and
mature technologies that will significantly expand the fleet?s
capability in comparison to its predecessor, the CH-53E
helicopter, by tripling the aircraft?s lift in high and hot
environments while reducing support and maintenance costs.
In
addition, the composite sponsors are designed to be
significantly more resilient to the environmental conditions,
ballistics and in-flight stress, while allowing for increased
cabin width without a change in vehicle footprint.
To meet
the demanding weight, durability and affordability objectives of
the CH-53K helicopter program, ITT is employing the latest
composite design and manufacturing technologies for these
important flight structures, including electronic model control,
laser-ply projection, five-axis computer numerically controlled
machining, automated trimming and drilling, as well as laser and
ultrasonic inspection of all subassemblies.
?We?ve
brought the best of our composite technology and experience to
produce a stronger, more durable and operationally flexible
aircraft to help the Marines perform their critical missions,?
said Jim Barber, vice president for ITT?s Integrated Structures
business area. ?ITT is committed to growing our composites
business so we can serve our customers? needs.? Production will
be accomplished at ITT?s Electronic Systems facility in |
