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 ϕ 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.

已使用快速压缩机（RCM）和高压冲击管（ST）对Jet A-1燃料样品进行了点火延迟时间（IDT）测量。IDT测量的压力范围为7至30 bar，温度范围为670 K至1200 K，燃油/空气当量比ϕ为0.3至1.3。获得了适合实验数据集的表达式，并提供了适合参数。RCM / ST组合数据旨在提供有关两阶段着火行为以及从NTC化学到高温自由基链支化的过渡的信息，这些信息在化学替代物的开发中非常重要且难以实现。
