Tiered suppliers to these partners (including small and medium sized enterprises) are critical to EFE and the full value chain needs to collaborate to achieve the programme objectives. This diversity will allow cross-sectoral knowledge transfer and innovation as well as yielding benefits such as an affordable and sustainable air transport system to society at large.

The development of a competitive aero engine is a long process, initiated by acquiring cutting-edge technology through research and technology programmes in a wide range of engineering disciplines. These unproven innovations need to be at a sufficiently low risk before they can be included in a product design, and we do this by using a representative demonstrator vehicle as part of the technology validation process. Only after successful technology validation can we consider a specific product design and verification programme for an engine entering service.
