Boeing Picks UTC to Design, Build 787-10 Engine Housings

United Technologies Aerospace Systems adds another entry to its Dreamliner supply Assembly in South Carolina More than 20 proprietary parts Aftermarket support, too

United Technologies Corp.’s UTC Aerospace will design and manufacture nacelles for Boeing Commercial Airplanes’ forthcoming 787-10 program, the next variant in the Dreamliner series. Last week Boeing announced the 787-10 would be assembled exclusively at its North Charleston, S.C., plant, rather than at more than one site as it does with the preceding two versions of the 787.

The value of the contract was not announced.

The 787 Dreamliner is Boeing’s new, long-range wide-body twin-engine passenger jet. Boeing also claims it is its most fuel-efficient commercial aircraft, with a structure based on a large volume of composite materials helping to reduce fuel consumption by up to 20% versus similar-size jets.

One of the Dreamliners’ distinguishing design details is the scalloped nacelles (external engine housings), meant to reduce engine noise.

The 787-10 is the largest jet in the 787 series, nearly 225 feet long, with a range up to 7,000 nautical miles. The length of the design was cited as one reason for Boeing’s recent decision to assembly the jets in North Charleston only, rather than at both that plant and the Everett, Wash., site.

UTC Aerospace Systems' Aerostructures business supplies more than 20 proprietary parts for previous entries in the Dreamliner series, including nacelles, inlets, thrust reversers, fan cowls and exhaust systems.

Its new assignment covers design and manufacturing of nacelle systems for both the GE Aviation GEnx and Rolls-Royce Trent 1000 engine variants.

Also, UTC Aerostructures will provide aftermarket support of the 787-10 nacelle systems through its global network of MRO overhaul facilities and spares.

"After being part of the Boeing 787 Dreamliner journey from concept to production for the past 10 years, we're gratified Boeing has selected us to continue the next leg with them," stated Aerostructures president Marc Duvall. "With outstanding dispatch reliability for our nacelle components on the in-service 787-8, we look forward to providing Boeing with the nacelle systems for the newest member of its Dreamliner family."

Boeing’s 787-9 is assembled at both the North Charleston and Everett plants, but the 787-10 design will be too long for convenient transport between the locations.
At Everett, Wash., Boeing Commercial Airplanes rolled out a 787-8, the first Boeing Dreamliner completed at the new rate of 10 airplanes/month. The buyer of this jet is International Lease Finance Corp., and it will be operated by Aeromexico.

A horizontal stabilizer is an elevating surface on the tail of fixed-wing aircraft, and is a critical design detail providing equilibrium, stability, and control of flight. The composite materials are critical to numerous components of Boeing’s 787, which was designed to carry high-volumes of passenger traffic over medium-range distances – and achieve energy savings.
Boeing South Carolina in North Charleston is one of two assembly plants for the 787, the first commercial jet built primarily from composite materials.
