A Honeywell International Inc. unit has awarded a contract to GKN plc's aerospace operation to supply nacelle systems for Honeywell's HTF7000 series business-jet turbofan engine.
The pact is expected to be worth more than $750 million and covers design, manufacture and integration with the engine. GKN Aerospace will deliver the complete propulsion system, podded into the nacelle, to the customer's assembly line.
The GKN Cowes facility on England's Isle of Wight plans to use polymer matrix composites in creating the fan cowl doors and inlet skins and barrels, and is considering composites for the inner and outer fan ducts and engine fan frames. Those frames are in use on engines for the U.S. government's F-35 Joint Strike Fighter program.
For the turbo prop nacelle doors, GKN will use standard epoxies at the cold end and bismaleimides at the hot end of the lower cowls and outer exhausts.
GKN Aerospace supplies a comparable nacelle system to Honeywell for the Challenger 300 business jet, made by Bombardier Inc. aerospace unit in Dorval, Quebec.
Honeywell's aerospace business segment is based in Phoenix.
