Hamilton Sundstrand Awarded Bombardier CSeries Aircraft Electrical Power System

Electric Power Generation and Distribution System (EPGDS) to perform power generation, power distribution, and load management functions.


WINDSOR LOCKS, CT -- Bombardier Aerospace has selected Hamilton Sundstrand to supply the electrical power system for the Bombardier CSeries family of commercial aircraft. Hamilton Sundstrand is a subsidiary of United Technologies Corp.

The Hamilton Sundstrand Electric Power Generation and Distribution System (EPGDS) performs power generation, power distribution and load management functions for the CSeries aircraft.

The EPGDS generates electrical power via two variable frequency generators and provides necessary interfaces with avionics and member systems to convey data and serve embedded utility loads throughout the aircraft. The EPGDS provides secondary load management through its five secondary power distribution assemblies, which receive alternating or direct current (AC/DC) power inputs from power centers, then manage and distribute the power to load equipment. Hamilton Sundstrand also provides emergency power via an electric air-driven generator.

"Hamilton Sundstrand is proud to play a key role with Bombardier in the CSeries aircraft program," says Joe Triompo, president, Hamilton Sundstrand Aerospace Power Systems. "Our experience and proven systems integration capabilities will be instrumental in supporting Bombardier's performance and operating cost objectives for this new commercial family of aircraft."

Hamilton Sundstrand projects the program value to be in excess of $2 billion over the life of the program.

The Electrical Power System for the CSeries aircraft will be primarily designed and manufactured in Hamilton Sundstrand's Rockford, IL, facility.

Bombardier also recently selected Kidde Aerospace & Defense, a subsidiary of Hamilton Sundstrand, to supply the CSeries aircraft's integrated fire protection system. Hamilton Sundstrand was previously selected by Pratt & Whitney to provide the control system — including the electronic, fuel, pneumatic, and thermal management systems — for its PurePower family of engines for the Bombardier CSeries aircraft.
