Ordnance Impacts on Jet Engine Fan Blades

Abstract

This report describes the experimental section of a program to investigate the damage that a .50 cal ogive inflicts on typical jet engine fan blade materials. Three materials, titanium, graphite epoxy composite and boron aluminum composite, were perforated by .50 caliber ogives at 488 m/s. The impact obliquities were investigated, 90 degrees and 60 degrees to trajectory. The momentum transfer during the impact was measured by use of a ballistic pendulum on which the targets were mounted. The momentum transfer was greatest for titanium, considerably lower for boron/aluminum and even lower for graphite expoxy. The results agree favorably with the calculated values at 90 degrees but differ at 60 degrees.
