Development of a Mach 1.5 Sand Erosion Test Apparatus is described. This rotating arm apparatus is designed to simulate the erosive environment which a turbine engine fan or compressor blade would see when operating with sand or dust ingestion. It will be used to evaluate the mechanisms of sand erosion and the relative erosion resistance of fan and compressor blade and coating materials at rotor tip speeds up to 1600 ftsec. This report describes the design and development of the apparatus including the rotating arm, power train, test enclosure, and sand control system. Calibration and correlation experiments are also described.
