Proving any leading edge solution that will last the life of the turbine is not a simple process. Accelerated, rain erosion test rigs where a glass fibre profile is coated with a test product, and spun round at a high angular velocity is currently the best method. advantEDGE have recently tested their solution using the Polytech test rig and have found it will last over 10 times longer than current blade material. This is a great result as advantEDGE is one of the only available solutions where the erosion protection of the rain effected surface is not dependant on the environmental condition it was originally applied in. This is also just the start as further tests are planned where more improvements have been implemented to further increase the life. This is just part of a much wider program of erosion and environmental condition trials currently being carried out.
