Abstract:

The program objective is to establish specific design criteria and provide the analytical design tools to assess and improve the foreign object damage tolerance of turbine engine fan and compressor blading. This program will aid in the design of more efficient damage-tolerant blading through the replacement of trial and error FOD test and evaluation practices with systematic transient structural analysis methods, test procedures and design criteria. A design system structure was completed and initial versions of the preliminary and final design transient structural response computer programs were developed. In addition, the interface between the bird loading model and the final design response model was completed. Three first stage blades were selected for modeling and testing. Tests and analyses to be used to generate local and gross structural damage design data are in progress and planning was completed for structural element impact tests. Composite and metallic specimens for local and gross damage testing were designed and most of these specimens have been fabricated. A parametric matrix to guide the analyses and validation testing was completed and FOD design criteria goals were formulated for consideration in the program.
