Dust erosion damage of military gas turbines is a serious problem in many current service areas. The subject program is designed to gain an improved understanding of the various mechanisms of dust erosion, as a basis for possible future development of turbine materials with improved innate erosion resistance. The experimental program is organized to evaluate the relative importance of erosion influencing variables introduced by the carrier gas, the dust suspension and the target materials themselves. The report describes the following functional tasks 1 the execution of the erosion test program, including the design and construction of special test equipment, 2 the analysis of erosion data and development of physical and mathematical models to define erosion mechanisms, and 3 organization of the erosion data in forms useful to the design engineer and the materials development specialist.
