By - Composite winglets extend range and cut operating costs
GKN Aerospace has delivered the first production aircraft set of winglets to Bombardier Aerospace, Belfast for the new Bombardier CSeries aircraft that will serve the 100- to 149-seat market segment.
Delivery of the composite winglets has followed a three-year design, test and initial manufacturing programme which has minimised winglet weight and complexity and maximised aircraft fuel efficiency through improved design and state-of-the-art manufacture and assembly. The CSeries aircraft is scheduled to enter into service in 2014.
The winglets will make an important contribution to the CSeries aircraft's targets in relation to fuel burn, emissions, range and performance, which will beat any current aircraft in its class. Across aviation, winglets are transforming the performance of aircraft, reducing wing drag to bring significant fuel savings
