Abstract

L'invention concerne la maintenance prédictive d'équipements électroniques embarqués dans un aéronef (1). Pour produire un pronostic, on prévoit : une étape de modélisation (48) de l'équipement (3) avec un modèle d'endommagement (53) par une agression externe ; une étape de simulation (49) d'endommagement jusqu'à défaillance ; une étape d'apprentissage (64) ; une étape de classification (65) de valeurs calculées et normalisées ; et une étape de fusion (61) donnant le pronostic réel de durée de vie en unité de temps avant maintenance. L'invention s'applique notamment à un aéronef (1) à voilure tournante, par exemple un drone d'hélicoptère.
