Civil engines
At GKN Aerospace, we design and develop engine components for today’s aircraft with an eye on tomorrow’s world. Using advanced lightweight materials and cutting-edge technologies like additive manufacturing, we meet the high demands of modern aviation while driving the industry towards a more sustainable future.

Powering a sustainable future of flight
With over 90% of new large passenger aircraft worldwide powered by our components, we continue to innovate and refine engine technologies that are more efficient, sustainable and technologically advanced than ever before.

With a lifecycle approach
Transforming aerospace one engine at a time
At GKN Aerospace, innovation is at the heart of everything we do. Not only do we design and deliver engine components aimed at reducing emissions and optimising fuel efficiency, but we also focus on designing lightweight structures that enhance performance.
Our design responsibility extends beyond initial development, covering the entire lifecycle of engine programmes – from addressing field issues and repair development to managing load condition and requirement updates. We work closely with our partners to ensure that sustainable flight is not just a vision but a reality at every stage of an engine’s life.

Wide-ranging expertise
Products and capabilities
Our expertise spans several high-performance engine components, including:
- Fan statics: Advanced cases and frames in titanium and composites for engines like the Trent XWB and GEnx
- Fan rotatives: Hubs and rotating components for maximum efficiency
- Low-pressure compressors: High-performance rotors
- Exhaust structures: Lightweight, aerodynamically optimised exhaust structures to reduce weight and improve performance

Research and development
Engine innovation through collaboration
At our global technology centre (GTC) in Trollhättan, we work alongside academics, industry leaders and research institutions to advance engine technologies. We’re at the forefront of creating aerospace solutions for a better tomorrow, participating in more sustainable engine system programmes and using state-of-the-art manufacturing techniques.
Part of the solution


Efficiency and reliability
Pioneering additive manufacturing
We leverage additive manufacturing (3D printing) to create complex, lightweight engine components that enhance performance and reduce environmental impact. This technology enables more precise designs, shorter production times and significant weight reductions, leading to improved fuel efficiency.

Revolutionizing fabrication
Leading the way in advanced engine structures
GKN Aerospace leads the industry in the fabrication of fan cases and turbine exhaust structures. We employ cutting-edge techniques like laser welding and aerodynamic duct optimisation to ensure maximum durability and performance. These innovations allow us to deliver tailored solutions that meet the challenges of civil aviation.
