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.
Claims12
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 monitoring system is characterised in that the said memory (7a) is integrated in the actuator.
A flight control actuator of an aircraft configured to be in connection with a computer (5) on board the aircraft, characterised in that it includes:
- sensors (3a, 3b) to collect, during each flight of the aircraft, series of measurements of parameters relative to the said actuator, and
- a non-volatile memory (7a) physically integrated in the actuator to store a set of damage indicators calculated by the said computer by using cumulatively the series of measurements observed during each of the aircraft's successive flights.
A method for monitoring a flight control actuator of an aircraft, characterised in that it includes the following steps:
- collecting, during each flight of the aircraft, series of measurements of parameters relative to the said actuator,
- calculating a set of damage indicators, using, in cumulative fashion, the series of measurements observed during each of the aircraft's successive flights, and
- recording the said set of damage indicators in a non-volatile memory physically integrated in the actuator.
