This report documents the results of testing conducted in July and August 2001 at the Naval AirWarfare Center-Weapons Division, China Lake, CA, as part of the continued effort to characterize uncontained engine events. This effort was performed in support of the Federal Aviation Administration Aircraft Catastrophic Failure Prevention Program. Data generated from this test will support the penetration equation development for the Uncontained Engine Debris Damage Analysis Model (UEDDAM), a developmental design tool for conducting aircraft safety analysis for engine rotor burst events. This testing investigated composite materials and metals for use in component shielding applications. Previous testing had focused on aircraft skins and structural components. Four materials were investigated during this series of testing: 2024-T351 aluminum, Ti-6Al-4V titanium, Inconel(Trade Name) 625 low-cycle fatigue, and a generalized composite. Impact data from these materials was used to characterize the ballistic response via a material constant within the penetration equations. This material property was previously denoted as the dynamic shear modulus. Examination of the ballistic limit equation used within the UEDDAM has determined that the material constant is more appropriately a shear constant. NTIS
