LIGHTNING PROTECTION MEASURES FOR AIRCRAFT FUEL SYSTEMS. PHASE 2

Abstract

Research was conducted to develop technology leading to methods of overcoming aircraft lightning strike hazards and to investigate the potential hazards introduced by these methods. The program included experimental and analytical investigations of (a) flame program included propagation characteristics through the 707 vent system, (b) the effectiveness of flame arresters of various designs located at different sections of the vent system, (c) explosion suppression techniques utilizing an explosively disseminated chemical agent to prevent explosion in aircraft tanks upon sensing a flame propagating through the vent tube, and (d) the previously reported ultra-high blast pressure effects and large volume plasma generation. Analytical evaluations were performed concerning the addition of air to the combustible vapor mixture to obtain high-velocity effluent from the vent outlet to prevent flashback, the use of mechanical valves to isolate vent passages, and the use of bladders as fuel containers. A purely theoretical analysis was performed to evaluate the potential hazards due to icing of selected flame arrester designs.
