The invention discloses a blade detection device. The device comprises a detector and at least one diversion coil arranged on a blade and along a periphery of the blade. The diversion coil possesses a first terminal and a second terminal which are next to each other and are arranged with an interval. The first terminal of the diversion coil is connected to a power supply. The second terminal of the diversion coil is grounded through a load so as to form a loop. After energization, the detector is used for detecting a state of the loop and outputting a detection result of a closed state or a disconnection state of the loop. The invention also discloses a blade detection method, a blade assembly, an aircraft and a control method thereof. In the invention, a damage condition of the blade can be accurately and automatically detected.
