Boeing awards seventh 7E7 contract to Hamilton Sundstrand

Boeing has selected Hamilton Sundstrand to provide the ram air turbine emergency power system for the all-new 7E7 Dreamliner, the seventh system awarded to the Connecticut-based company.

The ram air turbine, sometimes referred to as the RAT, is an emergency power system designed to provide electric and hydraulic power to the airplane in the event that other power sources are disrupted.

Hamilton Sundstrand is also supplying the 7E7's environmental control system, the electric power generating and start system, the remote power distribution system, the auxiliary power unit, the primary power distribution system and the nitrogen generation system.

"We couldn't be happier with the team we are assembling on the 7E7 program," said Mike Bair, senior vice president of the 7E7 program. "These are proven performers who understand the challenges and expectations we are facing and they are helping us develop solutions for our customers."
