Foam Overhead Cover Support (FOCOS) System for Dismounted and Mounted TOW Positions

摘要

This report presents the results of a concept development study of the use of polyurethane foam in constructing protective overhead cover support for TOW fighting positions. Two principal methods of cover support fabrication were considered: 1. A two component spray polyeurethane fabrication foam applied on a prepared form. 2. Hand-mixed polyurethane foam expanded within a fabric form. In both cases, an arch-shaped support with a 4-ft (1.2-m) radius and a 5-ft(1.5-m) length was made. The foam-filled fabric form was selected as having the highest potential for successful application by weapon crews. Subsequent field tests of the selected system demonstrated that a TWO weapon crew can erect an effective cover support system in field without special tools or equipment. (Author)
