The partnership between GKN Aerospace and Pratt & Whitney is being taken to a new level with the GTF™ engines that power the Airbus A220 and Embraer E-Jet E2 aircraft. The production of low-pressure compressor (LPC) aerofoils for the Pratt & Whitney PW1500G and PW1900G engines is being enhanced through GKN Aerospace’s advanced robotic milling and super-polishing technologies.
GKN Aerospace has expanded its existing Risk and Revenue Sharing Programme (RRSP) with RTX-owned Pratt & Whitney, signing a new agreement that covers the majority of the main aerofoils in the low-pressure system. Under the terms of the deal, the company will continue to provide component supply and engineering support throughout the service life of the engines, which is expected to span several decades to come.
GKN Aerospace and Pratt & Whitney Concentrate Production in Newington
What began as low-volume production in 2018 has since evolved into a highly automated operation at the company’s Newington facility. Robotic milling has minimised tolerance deviations, while in-house super-polishing technology has shortened lead times and boosted efficiency.
Joakim Andersson, President of GKN Aerospace’s Engines division, described the move as a strong endorsement of the company’s capabilities in the aerofoil and blade & vane sector. He added that it provides long-term stability for the Newington facility and positions the company for growth opportunities on next-generation engine platforms.

The agreement further cements Newington’s status as a centre of excellence in metallic aircraft engine components.
The teams’ next focus will be on ramping up production, with the goal of reaching full-rate serial production by the third quarter of this year (2026).
