To understand the effects of SAF introduction on the initial contrail formation process, soot (nvPM) emission data taken from combustion experiments under the condition of a hypothetical in-flight condition was examined to use to estimate the initial crystal formation process. A flight mission analysis utilizing the examined soot emission index presents estimation of the potential of initial contrail formation, and the conditions and effects of low-sooting SAF application on the contrail formulation. The present study only treats the early stage of the contrail formation, a simulated flight path consideration gave insight into the understanding of the onset condition of the contrail.

摘要

To understand the effects of SAF introduction on the initial contrail formation process, soot (nvPM) emission data taken from combustion experiments under the condition of a hypothetical in-flight condition was examined to use to estimate the initial crystal formation process. A flight mission analysis utilizing the examined soot emission index presents estimation of the potential of initial contrail formation, and the conditions and effects of low-sooting SAF application on the contrail formulation. The present study only treats the early stage of the contrail formation, a simulated flight path consideration gave insight into the understanding of the onset condition of the contrail.
