Sikorsky receives ITT helo sub-assemblies

SALT LAKE CITY, Nov. 22 (UPI) -- ITT Corp. has delivered to Sikorsky Aircraft its first major composite structural subassemblies for the CH-53K heavy lift helicopter.

The company said the delivery follows nearly three years of advanced design, development, testing and manufacturing to provide sponsons for the aircraft and represent a significant technology advancement by applying composite materials to military aircraft that operate in harsh environments.

"We've brought the best of our composite technology and experience to produce a stronger, more durable and operationally flexible aircraft to help the U.S. 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."

Sponsons attach to each side of a helicopter fuselage and house components such as landing gear, fuel and other mechanical and electrical assemblies without compromising interior passenger or cargo space.

Each sponson 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 CH-53K program.

ITT said to meet the weight, durability and affordability objectives of the CH-53K helicopter program it used the latest composite design and manufacturing technologies, 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.
