C-Series-winglet

UK-based GKN Aerospace has delivered a first set of winglets to Bombardier Aerospace for the new CSeries aircraft.

This delivery comes after a three-year design, test and manufacturing programme, which has reduced the weight and complexity of winglet, resulting in maximised fuel efficiency of the aircraft.

GKN Aerospace stated that the winglets would contribute towards the CSeries jet’s targets to achieve reduced fuel burn, lower emissions, and greater range and improved performance compared with rival aircraft in the segment.

GKN Aerospace Europe and special products group chief executive officer Phil Swash said that the design and development of the winglet has involved the full expertise of the team.

"We are commencing now on a production programme that will continue beyond the end of the first quarter of this century," Swash added.

GKN Aerospace secured $100m contract from Bombardier in 2010 to design and manufacture the winglet for the CSeries airliner.

The delivery of first winglet was expected in early 2011 to support the aircraft’s entry into service in 2013.

Initially, the maiden flight for the CSeries jetliner was scheduled for the end of 2012, but was postponed due to supplier delays in the delivery of components.

CSeries aircraft, which is now scheduled to enter service in 2014, will serve the 100 to 149 seat market and compete with smaller aircraft built by Airbus and Boeing.

Powered by Pratt & Whitney PurePower PW1500G engines, the CSeries jets are expected to offer 20% fuel savings compared with rival jets, with a 15% operating cost advantage to airlines.
