Advanced manufacturing
Pioneering smart rocket test technologies
A key example of our forward-leaning approach is GKN Aerospace’s collaboration with Northrop Grumman on the SMART (Solid Motor Annual Rocket Technology) project. This partnership showcases our expertise in both space and aerospace propulsion systems.
Through this collaboration, GKN Aerospace has contributed cutting-edge technology to the development of smart demonstration rocket test motors. By leveraging advanced manufacturing techniques, including additive manufacturing (AM), we improved the production of rocket motor components. One of the key benefits has been the ability to drastically reduce lead times for manufacturing, with some processes achieving up to 75% time savings.

The GE9X engine
The GE9X engine, developed by GE Aerospace, is a major breakthrough in modern aviation. Designed to power Boeing's advanced 777X aircraft, it is the world’s largest and most fuel-efficient commercial jet engine. It is designed to operate with sustainable aviation fuels (SAFs), significantly reducing emissions, lowering noise levels, and enhancing fuel efficiency.
GKN Aerospace’s key contributions
GKN Aerospace play an essential role in the development and production of critical components for the GE9X engine. With decades of experience and a focus on innovation, we provide solutions that enhance the engine's performance and reliability.
1. Lightweight composite fan cases and spacers
We manufacture composite fan cases and spacers using advanced carbon-fiber composites. These lightweight components reduce the overall engine weight, contributing to improved fuel efficiency and lower emissions.
2. Additive manufacturing
Our cutting-edge additive manufacturing techniques, including Selective Laser Melting (SLM), allow us to produce high-precision engine parts. This advanced process helps optimize engine weight and performance by enabling the creation of complex, lightweight structures.
3. Advanced materials for durability
Thanks to our expertise in material science, we develop components that can withstand the extreme temperatures and pressures within the GE9X engine. These materials ensure the engine operates reliably and efficiently over time.
4. Collaborative engineering
We work closely with GE Aerospace to ensure that every component we produce meets the highest safety and efficiency standards. This partnership is a testament to our ability to support some of the most demanding aerospace projects.

Reducing environmental impact
From research to reality
Since the 1990s, GKN Aerospace has been a key partner in major European research projects, including Clean Sky, which focuses on reducing aviation’s environmental impact. Through these initiatives, we are shaping the future of aerospace by driving sustainable practices and introducing cutting-edge technologies that redefine what’s possible.

Sustainable manufacturing
Expanding our capabilities
In line with our commitment to innovation, we recently invested $50 million to expand our industry-leading sustainable additive manufacturing capabilities. This investment enhances our ability to produce lightweight, high-performance components, accelerating the aerospace industry’s transition to sustainable propulsion technologies.
