“…Finnie [2 and Smeltzer, at al. [3] have conducted theoretical analyses of the erosion of ductile materials. In more recent investigations [1,4,5], further insight into the actual mechanism of erosion has been obtained by examining the target surface at high magnification using metallographic techniques and electron microscopy.…”

In operating gas turbine engines in dusty environments, severe erosion of compressor and turbine components results. This erosion adversely effects engine performance. Predicting erosion in the rotating machine of gas turbine is a complex problem. This paper presents test data from the high temperature material erosion facility at the University of Cincinnati. Data was obtained between a target temperature of ambient and 649°C (1200°F) for AM355, Rene 41 and L605 cobalt. In addition, particle velocity and impingement angle were varied.

“…The investigation of Smeltzer and Compton on the mechanisms of erosion was not complete at this writing (32,33). Their work includes not only the determination of the significance of particle size and concentration, angle of particle impingement, type of metal subjected to erosion, type of dust and particle impact velocity; but also air pressure, temperature of the specimen, stress in the specimen and heat treatment of the specimen.…”

“…Maximum erosion can occur at impingement angles ranging from about 20 deg for soft materials to 90 deg for brittle materials (18,33,35,37,38). For a typical steel compressor blade material, the impingement angle of maximum erosion is between 30 and 40 deg.…”

The object of this paper is to present in one place most of the documented experience that shows the interrelationship of gas turbines, dust and air cleaners; and to compare opinions on what an air cleaner must do to prevent a gas turbine from failing because of air-borne contaminants. This experience covers three types of gas turbine air cleaners in both the laboratory and the field, on wheeled and tracked vehicles, and on helicopters and air cushion vehicles. The consensus is that gas turbines do need air cleaners if they are going to compete with piston engines in their environment. The information is presented so that a person specifying a gas turbine air cleaner knows what factors he must consider, and can determine the relative importance of the features of the air cleaner that would best suit his needs.
