Abstract : This program was undertaken to establish the feasibility of using superhybrid materials for the manufacture and testing of large fan blades. In addition it was the objective of this program to investigate the FOD resistance of large metal spar/superhybrid fan blades. The technical effort reported herein was comprised of several elements of work, conducted in series. These elements included: (1) Preliminary blade design; (2) Detailed analysis of two selected superhybrid blade designs; (3) Manufacture of two process evaluation blades and destructive evaluation; and (4) Manufacture and whirligig testing of six prototype superhybrid blades.
