This study investigated the application of C6F12O in inhibiting RP-3 jet fuel fires. The ignition delay time (IDT) of C6F12O/air and RP-3/air with added C6F12O was measured using a shock tube. The results showed that C6F12O had a short IDT and was less temperature-sensitive compared to common fuels. The study provides a basis for the chemical kinetics analysis of C6F12O inhibition of RP-3 jet fuel combustion.
RP-3 jet fuel is the main fuel for aircraft in China,and it isalso a source of fire. C6F12O (Novec 1230) hasan outstanding fire extinguishing performance and minimal environmentalimpacts. In this study, the application of C6F12O in the inhibition of RP-3 jet fuel fire was considered, and theignition delay time (IDT) of C6F12O/air andRP-3/air adding C6F12O was measured using ashock tube. In addition, the results showed that the IDT of C6F12O was 500-900 & mu;s and less sensitiveto temperature compared with those of common fuels in the range of1150-1958 K, and the influence of C6F12O on the IDT of RP-3 jet fuel was influenced by many factors includingtemperature, the concentration of C6F12O, andthe stoichiometric ratio of RP-3 jet fuel. According to the experimentalresults, the mechanism of C6F12O was verifiedand modified, and then integrated with the mechanisms of RP-3 jetfuel; the integrated mechanism can well predict the IDT of C6F12O/air and RP-3/air adding C6F12O. This work provides a good basis for the chemical kinetics analysisof the inhibition of RP-3 jet fuel combustion by C6F12O.
