The aim of this study is to clarify stability of a drone in a narrow space. In this study, behavior of a drone in a narrow duct was investigated. Experiments were carried out using a drone with a size of 223×232×50 mm and a duct with a diameter of 1030 mm. The drone was installed with changing in axial, circumferential and radial positions of the duct. A range in which a drone can stably fly in a duct was examined and shown as a map. A lot of vibration patterns of a drone were investigated in some points, some of them vibrates strongly and the other points vibrates weaker than those points. With respect to the radial direction of the duct, the closer the center, the more stable the hovering of the drones. The drone was relatively unstable on the lower side compared to the upper side of the duct.
