Abstract
A holographic inspection method was developed for composite spar/shell fan blades, such as an experimental fan blade and an advanced fan blade. This method was employed to insure the quality of newly fabricated blades. Holographic inspection also was used to indicate initiation and growth of cracks as a result of resonant fatigue testing and spin testing. Metallographic examinations were conducted to show the good correlation between the holographic data and actual blade structures.
