Patent number: 8876042Abstract: An assembly includes a unitary nacelle structure and an integrated fan housing for a gas turbine engine assembly. The unitary nacelle structure includes an inlet region and a fan cowl region, and is configured to at least partially circumscribe the integrated fan housing. The integrated fan housing comprises an integral composite structure and includes a fan case sized and configured for encircling a fan blade assembly of an associated gas turbine engine, a fan hub, and a plurality of fan outlet guide vanes. The unitary nacelle structure cooperates with the integrated fan housing to transfer static and dynamic loads directly to a support structure, rather than through the engine core, to minimize backbone bending.Type: GrantFiled: June 30, 2010Date of Patent: November 4, 2014Assignee: General Electric CompanyInventors: Donald George LaChapelle, Christopher Charles Glynn, Donald Lee Gardner, Stephen Craig Mitchell, Mullahalli Venkataramaniah Srinivas, Edward Atwood Rainous, David Lance Pennekamp
