Rain Erosion Testing

The leading edge of a wind turbine blade is exposed to rough conditions during operation. This sets high demands to the leading edge protection (LEP) solution.

The various LEP solutions must withstand extreme conditions, and therefore testing them is essential to understand their erosion behaviour and performance. Accelerated Rain Erosion Testing of a leading edge solution not only proves the performance of the product, but also enhances the understanding of failure modes and is therefore extremely valuable to the customer.

With the vast experience on LEP solutions in AeroNordic and a growing demand from both OEMs and material suppliers, we have decided to expand our services to include Rain Erosion Testing.

The construction of the substrate plays a vital role in the resulting performance of any LEP solution. In the new recommended practice from the DNV-GL work group, the substrates are required to reflect the actual blade substrate construction. Our technicians are experienced in processing virtually every known blade production and repair solution. This allows us to support the customers to validate their LEP solution for every operational blade type currently available.

This test rig combined with the processing skills of our workshop gives AeroNordic a unique position in the wind industry as an independent 3’rd party.

In AeroNordic, we always strive to excel on quality, and our RET is fully compliant to the DNVGL-RP-0171. Our dedicated and highly skilled technicians manufacture the test specimen and perform the RET test and the results are evaluated and documented by our excellent team of engineers.
