Device for detecting breakage of a primary path in a flight control actuator

摘要

A device (13) for detecting the breakage of a primary path in a flight control actuator, said actuator having a primary path (1) comprising a rotary hollow screw (2), a secondary path (10) comprising a safety rod (3) that reacts the load passing through the screw (2), said device (13) being characterized in that it comprises a position sensor (15), connected to the screw (2), to measure information representative of the angular position thereof, and a disconnection system (17) able to disconnect the screw (2) position sensor (15) in the event of relative movement of the rod (3) with respect to the screw (2) if there is a break in the primary path (1).

1. A device (13) for detecting breakage of a primary load path in a flight control actuator, said actuator having a primary load path (1) comprising a hollow rotary screw (2), a secondary load path (10) comprising a load-assuming safety rod (3) passing through the screw (2), said device (13) being characterized in that it includes a position sensor (15), connected to the screw (2) for measuring information representing its angular position, and a disconnection system (17), capable of disconnecting the position sensor (15) from the screw (2) in the event of relative displacement of the rod (3) with respect to the screw (2) upon a break of the primary load path (1).
