RP-3 jet fuel is the main fuel for aircraft in China,
and it is
also a source of fire. C6F12O (Novec 1230) has
an outstanding fire extinguishing performance and minimal environmental
impacts. In this study, the application of C6F12O in the inhibition of RP-3 jet fuel fire was considered, and the
ignition delay time (IDT) of C6F12O/air and
RP-3/air adding C6F12O was measured using a
shock tube. In addition, the results showed that the IDT of C6F12O was 500–900 μs and less sensitive
to temperature compared with those of common fuels in the range of
1150–1958 K, and the influence of C6F12O on the IDT of RP-3 jet fuel was influenced by many factors including
temperature, the concentration of C6F12O, and
the stoichiometric ratio of RP-3 jet fuel. According to the experimental
results, the mechanism of C6F12O was verified
and modified, and then integrated with the mechanisms of RP-3 jet
fuel; 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 analysis
of the inhibition of RP-3 jet fuel combustion by C6F12O.
