The ignition and combustion characteristics of aluminum droplets under two different environments of normal gravity and weightlessness were studied by an advanced experimental method. The results show that gravity has a great influence on the dynamic characteristics of aluminum droplet combustion and the morphological structure of combustion products. In addition, the composition and pressure of the oxidizing environment also affect the particle size, particle size distribution and morphology of the combustion products.
