Boeing has awarded a contract to UTC Aerospace Systems to provide complete nacelle systems for the 787-10 Dreamliner variant. The deal extends the existing contract awarded in 2004 for the provision of inlets, thrust reversers, fan cowls and exhaust systems for the GE and Rolls-Royce engine options on the 787-8 and 787-9.

With 80 years of experience and certification of more than 19 modern nacelle programs since 2011 – we know nacelles. We have the capability to design and manufacture the full aerodynamic structure that protects the jet engine and optimizes aircraft performance.
