<p>A new concept of the droplet array generation technique was proposed to realize a high quality and high reliability performance of microgravity experiments of multiple-droplet combustion. Each fuel droplet was formed on the intersection of the X-shape fine SiC fibers by supplying the liquid fuel through a fine glass tube. Several sets of the X-shape fibers and corresponding fine glass tubes were aligned at an interval to make a droplet array. All the droplets in array were simultaneously generated in a short time. In flame spread experiments, an end-droplet was ignited by a hot-wire igniter to initiate the flame spread along the array. Microgravity experiments of droplet array combustion were demonstrated with the new droplet array generation technique using a drop experiment facility MGLAB in Japan. In microgravity, large droplets, which were often failed to be generated in normal gravity, were successfully generated through this method. The present technique is also effective in droplet array combustion experiments using a high-volatility fuel, whose prevaporization is not negligible. The flame spread rate and the flame spread limit of linear droplet arrays were compared with existing experimental results. Effects of the suspending fiber on the flame spread were also discussed.</p>
