Advancing next-generation low-emission aircraft – OFELIA

GKN Aerospace is contributing to the development of next-generation aircraft propulsion through OFELIA, a Clean Aviation-funded programme supporting technologies that reduce the environmental impact of small- and medium-range aircraft.

The project focuses on advancing the Open Fan engine architecture, one of the most promising pathways to improve fuel efficiency and support industry targets to reduce aviation emissions by around 20% versus 2020 levels, with potential entry into service from the mid-2030s.

Launched in November 2022 and led by Safran as part of a major European consortium, OFELIA is advancing promising propulsion technologies from concept stage to real-world testing, culminating in a full-scale demonstration of a next-generation engine low-pressure system. The project also evaluates compatibility with sustainable aviation fuels and hydrogen, and works with airframers and regulators to address installation and certification considerations.  Together, these activities support the aviation sector’s pathway toward climate-neutral flight by 2050.

GKN Aerospace’s contribution focuses on the design and manufacture of advanced load-carrying structures, leveraging its expertise in lightweight multifunctional design of critical structures for the next generation of engine architectures. Through the project, GKN Aerospace is also demonstrating new additive manufacturing capabilities, including the production of one of the largest titanium cases manufactured using Laser Direct Energy Deposition – wire technology. These innovations enable lighter components, reduced material waste, and improved production efficiency, supporting both environmental performance and long-term market competitiveness
