UTC to supply nacelles for latest Dreamliner

LOS ANGELES — More than a half dozen of United Technologies Corp.’s (UTC’s) operations and its suppliers will build the engine nacelle systems for Boeing Co.’s new 787-10 Dreamliner.

The aerostructures business of UTC’s Charlotte, N.C.-based UTC Aerospace Systems unit, which has built the nacelles for the initial two versions of the Dreamliner, has been picked by Chicago-based Boeing for the same role on the newest version, due to begin final assembly in 2017. No financial details were disclosed.

The aerostructures unit will provide inlets, thrust reversers, fan cowls and exhaust systems for the engine options offered by both Fairfield, Conn.-based General Electric Co. and London-based Rolls-Royce Plc, UTC said.

The nacelle system contains about 60-percent composites, 30-percent aluminum and 10-percent titanium and other materials, according to a spokesman for UTC’s aerostructures business in Chula Vista, Calif.

Titanium is used mainly in the highest-temperature areas, such as the exhaust nozzles, forward bulkheads for inlets and the core cowl, he noted.

The UTC aerostructures operations participating in 787-10 work include its Everett, Wash., facility, for the inlet; and its Riverside, Calif., plant, which makes the inner barrels, the spokesman said. Thrust reversers are produced at the Mexicali, Mexico, facility, with Riverside making the inner fixed structures. The exhaust system is built by the San Marcos, Texas, facility.

In addition, the actuation system for the thrust reversers will be made primarily in Britain and France by UTC Aerospace Systems’ actuation and propeller systems operations.

Moreover, the fan cowls are provided by UTC supplier Composites Technology Research Malaysia Sdn Bhd (CTRM), Selangor, Malaysia, while the translating sleeve—a key part of the thrust reverser system—will come from Austrian supplier FACC AG.

UTC Aerospace Systems also supplies more than 20 proprietary components and systems for the 787, the subsidiary of Hartford, Conn.-based UTC said.

Marc Duvall, president of the aerostructures segment, said in a statement that his group has been on the 787 program "from concept to production" over the past 10 years. The 787-10, the longest version of the Dreamliner, will carry 323 passengers up to 7,000 nautical miles.
