Despite current fire prevention and mitigation approaches, fuel flammability can overwhelm post-crash fire scenarios. The Workshop on Aviation Fuels with Improved Fire Safety was held November 19-20, 1996 to review the current state of development, technological needs, and promising technology for the future development of aviation fuels that are most resistant to ignition during a crash. This book contains a summary of workshop discussions and 11 presented papers in the areas of fuel and additive technologies, aircraft fuel system requirements, and the characterization of fuel fires. 606 $aAirplanes$xFuel 606 $aAirplanes$xFuel consumption 606 $aFire prevention 615 0$aAirplanes$xFuel. 615 0$aAirplanes$xFuel consumption. 615 0$aFire prevention. 676 $a629.134/351 712 02$aNational Research Council (U.S.) 712 02$aNational Research Council (U.S.).$bCommittee on Aviation Fuels with Improved Fire Safety. 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9910969774003321 996 $aAviation fuels with improved fire safety$94469359 997 $aUNINA
