COMFORT AND STABILITY RATINGS FOR PROTOTYPE LINCLOE TITANIUM HELMET SYSTEM

Abstract

Six test subjects awarded comfort and stability ratings for the standard 3.16 pound M-1 steel helmet system and an experimental 1.53 pound LINCLOE one-piece titanium helmet system. The suspension system of the experimental helmet was attached directly to the titanium ballistic shell, obviating the need for a helmet liner. Subjective ratings were recorded for: ease of adjustment of the suspension system comfort, helmet warmth, location of chinstrap, interference with hearing, noise produced by the helmet, interference with aiming the carbine and stability when running, jumping, grenade throwing and crawling under a wire obstacle. After scaling, differences between the ratings for the experimental and the standard systems underwent t-testing for significance. There was only one significant difference between the two systems: the experimental system was rated as more stable when throwing grenades. It is suspected that the M-1 helmet was rated as inferior on this task because it tipped forward, interfering with vision, while the experimental system did not.
