Fifteen various Army aircraft were examined to determine if a fire suppressant, void filler foam kit could be designed for each of them that would fill the void space surrounding the lower hemisphere of the fuel tank, thus reducing the susceptibility of the aircraft to fire from incendiary rounds. Low- density polyurethane foam was investigated for the outer walls of the fuel tanks, fuel system components, and in all areas where a spark may be generated in the presence of fuel vapor. Fluorocarbon film was selected for covering the foam. No adverse flight characteristics were discovered with any of the foam kits installed. The plastic film envelope covering some of the blocks was improperly sealed, allowing an increase in the weight of the blocks due to liquid absorption.
