Abstract
A blade inspection system includes: a transmitter of electromagnetic waves mounted in a first unmanned aerial vehicle (UAV); a receiver of electromagnetic waves mounted in a second UAV; at least one processor communicably coupled to the transmitter and the receiver; and a memory storing instructions executable by the at least one processor. The instructions causes the at least one processor to execute: emitting electromagnetic waves from the transmitter to the rotating surfaces of the blades of a wind power plant in a state where the first UAV and the second UAV face each other with the blades sandwiched therebetween; receiving, by the receiver, at least one of a reflected wave and a diffracted wave generated by the blades due to the emission of the electromagnetic waves from the transmitter; and determining whether there is an abnormality in the blades through analysis of the reflected wave or the diffracted wave.
