Skew detection system for aircraft lifting surfaces

摘要

The system has units that are arranged on two shutters, respectively, where the units are arranged against each other and cooperate for triggering an alarm from determined misalignment of the shutters. One of the units include magnetic sensors (31-33) e.g. hall-effect sensors, delivering an electric signal to an electronic processing unit, where the electric signal represents a position of the sensors with respect to a magnet (30) e.g. neodymium-iron-bore magnetic material. The electronic processing unit provides an alarm signal when the determined misalignment is reached.
