Abstract

L’invention concerne un système de détection de fuites (2) d’un moteur d’un aéronef comprenant :- un réservoir (10) ayant une ouverture de sortie (18);- un système de tuyauterie (12) comprenant une conduite principale (20) ayant une première portion de conduite (22) connectée à l’ouverture de sortie du réservoir et une deuxième portion de conduite (26) connectée au système d’injection du carburant de la chambre de combustion ;- un premier capteur (28), apte à estimer un débit instantané de carburant sortant du réservoir, - un deuxième capteur (30), apte à estimer un débit instantané de carburant entrant dans la chambre de combustion,- un contrôleur (32) configuré pour calculer une différence entre le débit instantané estimé par le premier capteur et le débit instantané estimé par le deuxième capteur pour la présence d’une fuite dans la conduite principale. Figure à publier avec l’abrégé : Figure 1The invention relates to a leak detection system (2) of an aircraft engine comprising: - a tank (10) having an outlet opening (18); - a piping system (12) comprising a main pipe (20) having a first pipe portion (22) connected to the outlet opening of the tank and a second pipe portion (26) connected to the fuel injection system of the combustion chamber; - a first sensor (28) ), capable of estimating an instantaneous flow rate of fuel leaving the tank, - a second sensor (30), capable of estimating an instantaneous flow rate of fuel entering the combustion chamber, - a controller (32) configured to calculate a difference between the instantaneous flow estimated by the first sensor and the instantaneous flow estimated by the second sensor for the presence of a leak in the main pipe.
