TELEPHONE NUMBER (include area code) N/A Standard Form 298 (Rev. 8-98) Prescribed by ANSI Std. 239.18 Decomposition rates of gas-phase kerosene-based fuels and surrogates with and without the addition of a thermal stabilizer additive were measured at high temperatures in an aerosol shock tube. Fuels studied include RP-1, RP-2, and n-dodecane, and the thermal stabilizer studied was 1,2,3,4-tetrahydroquinoline. Decomposition rates were measured in approximately 0.5% fuel/argon mixtures for temperatures of 1100 to 1300 K and pressures of 3 to 8 atm. Fuel concentration was measured using infrared laser absorption at 3.39 micrometers. The decomposition rates for neat RP-1 and RP-2 were found to be very similar and were found to be slower than that of a simple kerosene surrogate, n-dodecane.
