Leading edge protection

The problem

Composite propellers, next-generation aircraft wings, and wind turbine blades are pushing aerodynamic and efficiency boundaries — but their leading edges are highly vulnerable to erosion and impact damage.

Conventional metal leading edge guards, especially those made from sheet-pressed titanium, present challenges:

  • Excess weight that reduces overall efficiency
  • Inferior geometry control, especially on dual-curvature or complex shapes
  • Reduced thickness at the edge where protection is needed most
  • Limited ability to integrate seamlessly with composite or polymer structures

Our solution: 

Ultima Forma produces tough electroformed nickel and nickel-cobalt leading-edge guards that are both lighter and more erosion-resistant than titanium.

CAE is used to simulate leading edge performance and propose suitable design solutions to customer use cases.

Using our proprietary electroforming process, we:

  • Tailor thickness — reinforcing the edge where impacts occur, reducing material on the sides to save weight
  • Maintain complex 3D geometry, including dual curvature designs for advanced aero performance
  • Bond or co-mould directly to composite or polymer structures for seamless integration
  • Deliver precision fit and repeatability through digital design-to-manufacture workflows

Why it is better:

  • Up to 90% lighter than solid titanium for equivalent protection
  • 10× better volumetric loss resistance from particle erosion
  • Functionally graded construction — thicker at the leading edge for strength, thinner at the sides for mass efficiency
  • Compatible with high-volume automated manufacture and QA control
  • Already in trial use with aerospace partners, supported by a UK grant to scale production
