Rain Erosion Test specimens
High Precision Specimens for Rain Erosion Testing
Olsen Wings produces RET specimens made for testing LEP systems, soft shells and advanced coatings under extreme erosion-inducing conditions.
Each specimen is manufactured with controlled balance, geometry and surface finish to ensure valid and repeatable results in high speed RET facilities.
Precisioned for Critical, High Cost Validation
Rain Erosion Testing is one of the most expensive validation processes in materials development. As offshore wind deployment increases, leading edge erosion intensifies, making controlled and repeatable RET evaluation increasingly important.
A single invalid test cycle can delay projects, compromise qualification timelines and increase costs. This makes specimen precision essential.
Our RET specimens remove uncertainty from the test setup and ensure that results reflect actual material performance rather than sample imperfections.
For R&D teams and OEMs working under tight budgets and strict performance targets, this reliability is a clear advantage.
Flexible Configuration for R&D Requirements
Specimens can be customised in geometry, thickness, offsets and material composition, typically in epoxy systems. Specimens can be produced in multiple layups, weights and offsets, leaving room for additional material layers when required for advanced comparative studies. Typical specimen imbalance is controlled tightly between 0.05 g and 0.30 g to secure stability in high‑speed test environments.
We can also supply specimens with specific coatings or multi layer build ups to match customer test setups and evaluation criteria.
Reliable Coating Evaluation
Coating developers use our RET specimens to validate erosion resistance, bond durability and coating performance under accelerated loading. The controlled geometry and reproducible surface quality allow coating systems to be compared on equal terms and avoid invalid results in qualification programs.
Reliable Data for Research and Testing
Universities and independent test centres rely on our RET specimens for research grade erosion studies and comparative testing.
Stable mass distribution and consistent surface accuracy ensure that data reflects material behaviour rather than variations in specimen design, which is essential for academic research and collaborative industry projects.
