The test facilities designed thus far did not simulate the aerodynamic effect of the flow field over the erosion specimen. This effect can be a very important factor in turbomachine erosion, where the flow is constantly turned by rotating and stationary cascades. Two erosion test facilities were, therefore, built during the course of this study. The first wind tunnel with a stationary specimen was designed to obtain basic erosion data, particle impact, and rebound characteristics. Another unique test facility was then designed to simulate and measure the erosion of turbomachine blades. With the basic information developed in this test facility and the empirical relations derived therefrom, the necessary data are available to calculate the material removed by erosion. This, together with an analysis of particle trajectories in turbomachines, can be used in the prediction of erosion of the different turbine components by the ash particles.
