Patent Images
1. A monitoring system for monitoring a flight control actuator of an aircraft, comprising:
- an actuator including;
sensors that collect, during each flight of the aircraft, a series of measurements of parameters relative to said actuator,memory, physically integrated in said actuator, that stores a set of damage indicators, anda control module physically integrated in said actuator and connected to said sensors; and
a processor, which is installed on board the aircraft and is external to said actuator, that calculates the set of damage indicators using, cumulatively, the series of measurements collected during each of the aircraft'"'"'s flights,wherein said control module sends the series of measurements via a communication system of the aircraft to said processor, andwherein said processor calculates the damage indicators in real time, before sending the damage indicators to said control module, said control module storing the calculated damage indicators from said processor in said memory.

Abstract
The invention concerns a system for monitoring a flight control actuator of an aircraft, including:
- an actuator (1),
- sensors (3a-3d) in the actuator (1) to collect, during each flight of the aircraft, series of measurements of parameters relative to the said actuator,
- processing means (5) to calculate a set of damage indicators using, cumulatively, the series of measurements observed during each of the aircraft'"'"'s successive flights, and
- a memory (7; 7a) to store the said set of damage indicators, where the said memory is integrated in the actuator.
