Ignition delay time (IDT) measurements for Jet A-1 fuel samples have been performed with a rapid compression machine (RCM) and a high-pressure shock tube (ST). The IDT measurements span a pressure range from 7 to 30 bar, a temperature range from 670 K to 1200 K, and fuel/air equivalence ratios phi from 0.3 to 1.3. Expressions fitting the experimental data sets were obtained, with fitting parameters being provided. The combined RCM/ST data aimed at providing information on the two-stage ignition behavior and on the transition from NTC chemistry to high-temperature radical chain-branching, which are important and hard to meet targets in the development of chemical surrogates.
