The modernization of military aircraft has included the addition of fuel tank fire/explosion protection. A military transport, like any other aircraft, is susceptible to fuel tank explosions from a number of sources, including combat gunfire. Studies have shown that the fuel tanks are the largest single contributor to the vulnerability from high explosive incendiary (HEI) rounds for transport aircraft. Since no aircraft has the inherent capability to suppress flames within the fuel tank ullage, it is important to provide a tank explosion protection system that prevents fires and explosions inside the fuel tanks during all modes of aircraft operation. The Lockheed Aeronautical Systems Company and the United States Air Force have acquired considerable knowledge about explosive suppressant foam through its use in the Lockheed-built C-130 aircraft. This foam material prevents or limits flame and pressure wave propagation and acts as an anti-slosh baffle. In-service experience with the foam is discussed. Associated maintenance problems and impacts on man-hours, weight, and cost is also reviewed. The status of the new foam materials being developed to eliminate electrostatic problems with the present explosion suppressant foam will be stated and assessed. Alternative techniques and methods to achieve fuel tank explosion protection were proposed for the C-130 and will be compared to the performance of the foam installation. Finally, explosion suppression is put into perspective with other C-130 wing modernization features.
