PROGNOSTIC OF DURATION BEFORE MAINTENANCE BY FUSION BETWEEN MODELING AND SIMULATION, FOR ELECTRONIC EQUIPMENTS ON BOARD IN AN AIRCRAFT

摘要

The invention relates to the predictive maintenance of electronic equipment embedded in an aircraft (1). To produce a prognosis, provision is made for: a modeling step (48) of the equipment (3) with a damage model (53) by external aggression; a simulation step (49) of damage until failure; a learning step (64); a classification step (65) of calculated and normalized values; and a melting step (61) giving the real life expectancy in unit time before maintenance. The invention applies in particular to an aircraft (1) with a rotary wing, for example a helicopter drone.
