An efficient, economical, reliable method for reducing aircraft fuel tank explosion potential that can easily be manufactured or retrofitted to existing aircraft systems. Ducting means to connect an aircraft's propulsion or auxiliary power gas turbine jet engine air intake suction area to the aircraft's fuel tank ullage area to effect continuous or selective suction operation for removal of potentially explosive fuel fume-vapors and replacement of the fume-vapors with outside or temperature controlled outside air with lower-oxygen content air or inert su...
1. A method for using an aircraft's dedicated propulsive or, auxiliary power engines for purging and removing dangerous fuel fumes and heat from within said aircraft's, fuel tank or fuel tank compartment areas with replacement of said fumes and heat by cooler, mechanically refrigerated air or cabin-cockpit outflow air comprising:(a) a duct or conduit means interconnecting said aircraft's fuel tank ullage and fuel tank compartment areas and said aircraft's dedicated engine's outside air intake section for the transmission of said fuel fumes and hot air in...
