Abstract
In this paper, we develop flying boat type small UAV. In Japan, many disasters such as an earthquake and a volcanic eruption have occurred. UAVs play an important role in disasters since these are fit aerial photography. A helicopter type, an airship type and so on are major UAVs. However, a long flight is impossible for helicopter type. Moreover the lowness of mobility is demerit of airship type. In this study, we develop small UAV which is able to take off from water and land. The UAV also can fly at a low speed and observe various sites from the air.
