As a way of energy saving and emission reduction, the blended fuel strategy can effectively reduce the dependence on fossil energy. In this paper, a long-chain alcohol—n-butanol was selected and blended with aviation kerosene to study the spray characteristics of the blended fuel in a constant volume environment. The results show that at a blending ratio of 10%, the blended fuel and pure aviation kerosene show similar spray characteristics. As the blending ratio increased, the spray tip penetration and spray cone angle of the blended fuel were more different from those of aviation kerosene. The spray volume and mass of entrained gas of AKB10 and aviation kerosene were larger, showing a better fuel-gas mixing degree.
