Foreign Object Impact Design Criteria. Volume 3
Abstract
The program objective is to establish specific design criteria and provide the analytical design tools to assess and improve the foreign object damage (FOD) tolerance of turbine engine fan and compressor blading. The program will aid in the design of more efficient, damage-tolerant blading by replacing trial-and-error FOD test and evaluation practices with systematic transient- structural-analysis methods, test procedures, and design criteria. Task I has been completed. A design structure was developed for the purposes of providing a consistent framework in which to constitute the design criteria, guiding the overall technical effort, and formulating a data foundation to define the problem environment. The major part of Tasks II and III, development of the transient-structural-response and interactive-loading models and interfacing these models, was accomplished. Task IV through XI address local and structural impact testing, material-property determination, error-band analysis, and the formulation of design criteria. All of the Task IV testing to establish the properties for the metallic materials in the program has been completed, and testing is currently underway to establish the properties for the composite materials that are under investigation. Tests and analysis for the generation of local and gross structural-damage design data are in progress, and bench testing of structural elements for analysis validation is nearing completion. Single- blade whirligig testing has started, and the R and D test plan for a full stage of shrouded F101 blades has been completed.
