Abstract
Official abstract text for this publication.
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 ).
First claim
Opening claim text (preview).
The invention claimed is: 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 positio…
