The exposure results of ten experimental rain erosion resistant coatings on an F-100F aircraft which penetrated thunderstorms as part of the Project Rough Rider flight tests have been correlated to whirling arm erosion simulation results. The rankings of the erosion resistance of materials determined on the whirling arm were similar for the same materials in actual flight exposures. Because the results from the whirling arm technique and the flight tests were similar, the whirling arm is considered to be a good research tool for exploratory development of rain erosion resistant materials.
