Abstract

Un système d'aéronef comprend un ventilateur, un capteur de pression différentielle, un capteur de température et un contrôleur de système. Le ventilateur fournit un flux d'air à au moins un échangeur de chaleur. Le capteur de pression différentielle détecte une différence de pression entre une entrée du ventilateur et une sortie du diffuseur du ventilateur. Le capteur de température détecte une température à l'entrée du ventilateur. Le contrôleur de système est paramétré pour pouvoir recevoir la différence de pression détectée, la température détectée et une vitesse du ventilateur, et il détermine un point de fonctionnement du ventilateur en se basant en outre sur la différence de pression détectée, la vitesse du ventilateur et la température détectée. Le point de fonctionnement indique la contamination d'au moins un échangeur de chaleur.
