Sand erosion is a phenomenon whereby solid particles impinging on a wall cause serious mechanical damage to the wall surface. Aircraft engines operating in a particulate environment are subjected to the performance and lifetime deterioration due to sand erosion. Especially, the compressor of the aircraft engines is severely damaged. In our previous study, we developed a three dimensional sand erosion prediction code and applied it to a subsonic axial compressor. However, design trends for modern compressors continue to increase blade loadings and decrease aspect ratios, and a modern compressor is a transonic compressor. Therefore, it is important to study sand erosion on such as transonic compressors for designs. In the present study, Rotor 37 is used on sand erosion simulations and the particle motion and erosion rate and so on are investigated.
