Abstract

L’invention concerne un système de lubrification (100) pour turbomachine d’aéronef, comprenant : - un réservoir de lubrifiant (26) ; - un orifice (42) de retour de lubrifiant prévu sur le réservoir ; - un séparateur air-lubrifiant (32) ; - une canalisation (30) d’extraction d’air chargé de lubrifiant, agencée entre le réservoir (26) et le séparateur (32) ; - un échangeur lubrifiant-carburant (36) alimenté par du lubrifiant avant son passage par l’orifice de retour de lubrifiant (42) prévu sur le réservoir. Selon l’invention, le système comporte un dispositif (52) de détection de fuite de carburant dans l’échangeur, le dispositif de détection de fuite comprenant un accéléromètre (54) monté sur la canalisation d’extraction (30) et configuré pour identifier le passage dans cette canalisation d’un mélange de lubrifiant et de carburant se produisant en cas de fuite dans l’échangeur (36). Figure pour l’abrégé : figure 2The invention relates to a lubrication system (100) for an aircraft turbomachine, comprising: - a lubricant reservoir (26); - a lubricant return orifice (42) provided on the reservoir; - an air-lubricant separator (32); - a pipe (30) for extracting air charged with lubricant, arranged between the reservoir (26) and the separator (32); - A lubricant-fuel exchanger (36) supplied with lubricant before it passes through the lubricant return port (42) provided on the tank. According to the invention, the system comprises a device (52) for detecting a fuel leak in the exchanger, the leak detection device comprising an accelerometer (54) mounted on the extraction pipe (30) and configured to identify the passage through this pipe of a mixture of lubricant and fuel occurring in the event of a leak in the exchanger (36).
