Abstract: An unmanned aircraft 1 according to an embodiment of the present invention provides an unmanned aircraft that properly makes a forced landing in case of an abnormality. The unmanned aircraft 1 is configured as a multicopter that flies with lift and thrust generated by rotation of six rotors 13. The unmanned aircraft 1 identifies a forced landing site in a case of having detected an abnormality during flight and controls motors 12 configured to drive the respective rotors 13, to make a landing at the identified forced landing site. The unmanned aircraft 1 is consequently enabled to make an autonomous forced landing at a specific site in case of an abnormality.

Abstract: The objective of the present invention is to provide a device configuration, a method and the like for performing an imaging survey within a survey space using an unmanned aerial vehicle. Provided is an unmanned aerial vehicle provided with at least four rotating blades, and a control unit which controls the rotation of the at least four rotating blades, wherein the unmanned aerial vehicle is provided with a survey camera in a position on a chassis of the unmanned aerial vehicle, between at least one rotating blade positioned on the side in the direction of travel, from among the at least four rotating blades, and at least one rotating blade positioned on the opposite side to the direction of travel, and wherein, when flying above a surface in which a liquid is at least partially present, the unmanned aerial vehicle flies while at least partially preventing scattered liquid from reaching above the chassis by means of the at least four rotating blades.
