Extensive high temperature solid particle rebound characteristics testing and analysis has been continuing at the University of Cincinnati. These measurements have been done in the high temperature erosion wind tunnel facility. The target material effect on rebounding characteristics when exposed to high temperatures has been investigated analytically. In addition, measurements have been completed for the following target materials: INCO 718, Ti 6-4, 2024 Al, Lead and Beryllium. Useful particle rebound characteristics have been derived from the measured data. The measured impulse relationship can be used to estimate the force interaction between the particle and the target material during the impact event. The particle rebound characteristics are very important parameters for calculating the particle trajectories and consequently predicting the erosion damages.

The paper presents various types of turbine scoops damages that are being found in the operating process of air turbine engines (TSO). When dividing them, having in mind a genesis of their origin, a special attention has been paid to corrosion and high-temperature erosion, often being a reason for destruction of the entire unit. The damages hereto described have been illustrated with examples collected during endoscope surveys of TSO internal spaces or their post-failure disassembly. The summary points out to the ways and directions of works aiming at early detection of TSO turbines units damages, and thus at improvement of their operating safety.
