This study was undertaken at AEDC to provide information relating to the impact on the environment when JP-4 fuel is jettisoned from jet planes. The specific areas investigated were 1 the physical breakup of the JP-4 into droplets, 2 the physical properties of JP-4, 3 the drag coefficient of JP-4 droplets, 4 the evaporation characteristics of JP-4 droplets, and 5 the effects of JP-4 on the atmospheric processes of condensation of water vapor. Data and information provided in the first four areas should be useful in developing a computer model to predict the eventual distribution of JP-4 from a specific fuel dump under particular atmospheric conditions. The results of the studies in the area of atmospheric condensation indicate JP-4 vapors should have neglibible effects. However, small JP-4 droplets may act as effective seed nuclei to initiate precipitation under favorable conditions.
