Leading Edge Protection

Leading Edge Protection (LEP) for wind turbines


PolyTech’s leading edge protection layer is designed to absorb the impact energy from raindrops and other particles and thereby  protecting the leading edge from the fatigue damage that eventually leads to erosion. 

Our concept uses pre-casted soft polyurethane shells tailored specifically to fit the geometry of the leading edge of the individual blade type. We optimise material thickness to provide maximum protection at the most stressed areas of the leading edge and minimise transitions with the original blade surface. The distortion of the aerodynamic blade profile is minimized so that our system provides a better aerodynamic performance compared to conventional leading edge protection systems.
