Abstract
With a device for error detection of adjustable flaps on aircraft wings, it is proposed that each flap is provided with a tube as a transmission element arranged in the wing span. The tube is connected fixedly at one end with the flap and is rotatably held. On the free end of the tube, a measuring arm is fixedly arranged on the tube and a sensor fixed to the flap structure is arranged. When an error occurs, the flap twists, whereby a distance change between the sensor and measuring arm occurs. The signals of the sensor are transmitted for error localization of each flap to an evaluation device, which switches off the drive via a control device with occurring errors.
