Abstract

The invention concerns a device for the recognition of residual synchronization errors of multiple slats or flaps placed next to each other in aircraft. According to the invention, a current-carrying wire is run through the slats or flaps placed next to each other. This wire is fastened at one end in the area of the gap between the slats or flaps and, on the other side, run through a cutting device. A detector can be used to detect and indicate the change in resistance when the wire is cut.

Claims

1. Device for the recognition of residual synchronization errors of multiple stats or flaps placed next to each other in aircraft,

characterized in that,

a current-carrying wire is fed through the slats or flaps arranged next to each other, where such wire is fastened at one end in the area of the gap between the slats or the flaps and on the other side fed through a cutting device and that, by means of a detector, the change in resistance can be detected when the wire is cut.

2. Device according to claim 1, characterized in that, the cutting device consists of an annular cutter.

3. Device according to claim 1 or claim 2, characterized in that, the distance between the wire and the cutter is selected in such a manner that the relative movement caused by wing flexing and installation tolerances between the slats or flaps arranged next to each other does not cause the wire to be cut.

4. Device according to one of the claims 1 though 3, characterized in that, the fastening of the wire at one end is done with at least one clamping screw.
