Development of an Unmanned Observation Aerial Vehicle (UAV) as a Tool for Volcano Survey Kazuto SAIKI῍ and Takeshi OHBA῍῍ An unmanned aerial vehicle (UAV) named “Osaka University Sky-+” was developed as a field survey tool based on the concept that the researchers and the sta# of the municipality who investigate volcanic field were able to operate it easily, safely, and at low cost. Sky-+ is a radio control airplane with wingspan of 3* cm. It is controlled by three channel signal for motor, aileron, and elevator. Remote control distance is about .** m limited by human distance vision. The strong points of Sky-+ are as follows ; custom-designed manufacturing of the black polypropylene foam for the airframe material, an electric ducted fan is employed to secure the safety, portable on one’s back because of the new design of the airframe division, the payload that reaches -** g is secured, and achievement of the high flight performance against the strong wind around +* m/s. Field test for Sky-+ was performed at Kusatsu-Shirane volcano on +/ May ,**2. During the field tests, Sky-+ obtained movies of the crater lake and data of H, S gas concentration in the air. A training course in assembly and operation of Sky-+ was held at Osaka University and Kansai Mokei Airport (KMA) on -ῌ. August ,**2. By the field test and the training course, we proved that the development concept of Sky-+ had been achieved. Key words : Unmanned Aerial Vehicle (UAV), radio control, airplane, volcanic survey. +ῌ ῐ ῎ ῑ ῏. 5,6789:;<=>?@A:B/C&>. D EF= GHIJK L+,MN O+ L. "#$%&'()*+,-./ 01 2 . +,&PK-Q RGS TU V%MW. X ,**.. Y!
