Feasibility of an Impact Shell for Combat Helmets

Abstract

An Impact Shell was developed to attenuate acceleration at higher velocities (14.1 ft/s and 17.3 ft/s) than the current Army helmet blunt impact requirements (10 ft/s). Baseline helmet blunt impact testing was completed using the Advanced Combat Helmet (ACH) at 14.1 ft/s and 17.3 ft/s and a variety of commercially available materials were evaluated as potential external energy absorbers. Two materials were down selected, evaluated and compared to the baseline using the Army's standard blunt impact test methodology at elevated impact velocities (14.1 ft/s and 17.3 ft/s).
