R&D installed the first Aerospace Rain Erosion Tester for a coating company. Based on a 3-bladed helicopter principle, the test specimens are shaped like the leading edges of an airplane wing. This test setup simulates and ensures conditions very similar to real-life harsh weather and rain in an accelerated way with very high repeatability.

With the Aerospace Rain Erosion Tester from R&D, it is possible to make unique and faster testing of erosion on the leading edges of airplane wings. By having a rain erosion tester in-house, the company can perform more precise and frequent testing of coatings – reducing costs and time-to-market,” explains Rasmus Refshauge, Key Account Manager at R&D.

R&D has installed a Rain Erosion Tester at five different coating companies that supply coating to the wind and aerospace industry.

Full DNV-GL and specification compliance

To simulate the speed of an airplane compared to a wind turbine, the test specimen maximum tip speed has been increased from 173 m/s to 224 m/s. The test system has a proven level of repeatability and complies with SAE AMS-C-83231A Aerospace Material Specification for Coatings. This test system has a proven level of repeatability and fulfills DNV GL's Recommended Practice (DNVGL-RP-0171) for the testing of rotor blade erosion protection systems.
