High-lift actuation

Goodrich Corporation has been selected by Bombardier to design and produce the high-lift actuation system for the Bombardier CSeries family of commercial aircraft.



These high-lift actuation systems will control the movements of the wings’ surfaces, which are deployed for take-off and landing to increase an aircraft’s lift co-efficient.


The selection is expected to generate more than $750m (£510m) in original equipment and aftermarket revenue over 20 years. The work will be performed by Goodrich’s Actuation Systems team in Wolverhampton.


Goodrich will provide a fully integrated high-lift flap-and-slat system for the aircraft, including actuators, power-drive units, wing-tip brakes, electronic control units, cockpit levers, transmission shafts and sensors.


The company claims that this design has undergone millions of high-lift flight hours with a range of aircraft.


The Goodrich team in Wolverhampton will also provide the thrust reverser actuation system, an integral part of the streamlined enclosure for the Pratt & Whitney PurePower PW1000G engine that will power the CSeries. Goodrich was selected to provide the nacelle system for the PW1000G in 2008.


‘In providing both the high-lift and thrust reverser actuation systems to Bombardier, we are leveraging our experience on these products to provide a truly integrated and optimised solution for the new-generation single-aisle CSeries aircraft,’ said Eric Schulz, president of Goodrich Actuation Systems.


Bombardier estimates that the CSeries aircraft, which is still in the design phase, will emit 20 per cent less CO2 and 50 per cent less NOx. The company also claims it will fly four times quieter and offer a 20 per cent fuel burn advantage. The company hopes that these factors will result in 15 per cent-improved cash operating costs compared to current in-production aircraft of a similar size.


Lufthansa is scheduled to receive up to 60 of the aircraft when they enter into service in 2013.
