Local Leading Edge Damage from Hard Particle and Soft Body Impacts (Task IVB)

Abstract

This report describes a study to experimentally determine the leading edge local response of typical blade materials to impact loading and derive analytical/empirical models of the response. The three fan blade type materials investigated were the J79 blade material of 403 stainless steel, the F101 blade material of 8A1-1Mo-IV (8-1-1) titanium and the APSI metal matrix blade material of boron/aluminum. The local leading edge damage problem was investigated on the three materials using glass beads, steel spheres, granite pebbles, ice, and artificial birds as the impactors. The resulting specimen damage for each impactor type and size was characterized by identifying the damage mode and quantifying the damage by making various damage measurements.
