Improved load detection on a flight control actuator

摘要

The actuator has a primary path including a hallow screw terminated by an attachment piece of the primary path, and a secondary path including a safety rod recovering load. The rod ends with a spherical head having clearance, when the primary path carries the load. The head is received in a female form of an attachment piece of the secondary path. Detection units detect the load of the secondary path. The detection units include bridge-type silicon sensors to detect the load on a fixation screw (12) assuring top attachment of the secondary path and to detect constraints of the secondary path.
