An investigation was conducted to establish the feasibility of using perforated hollow plastic spheres to pack aircraft fuel tanks to provide fire and explosion suppression capability. The program involved establishing several sphere configurations, producing test quantities, determining performance under electrical spark and incendiary gunfire conditions, and evaluating fuel system compatibility. These sphere configurations varying in diameter from 34 to 1 inch with perforations of 0.060 to 0.100 mils were evaluated. All configurations provided some explosion suppression, but the goal of 3 psi maximum peak pressure rise required for fuel tank applications was not achieved. Fuel system compatibility was slightly inferior to that experienced with polyurethane foam.
