Abstract

L'invention se situe dans le domaine de la surveillance de l'état d'un aéronef et, plus précisément, de l'état d'un turboréacteur équipant l'aéronef. Elle concerne un turboréacteur (10) à double flux équipé d'un système (30) de régulation du turboréacteur et de détection d'une anomalie de température dans le compartiment inter-veines. Selon l'invention, le système (30) de régulation et de détection comprend un thermocouple (22), un capteur de température de soudure froide (23) et un calculateur (21), une soudure chaude (223) du thermocouple (22) étant positionnée dans une veine primaire (14) du turboréacteur et deux soudures froides (224, 225) du thermocouple étant positionnées dans un compartiment inter-veines (132). Le capteur de température de soudure froide (23) est positionné dans le compartiment inter-veines (132) au voisinage des soudures froides (224, 225). Le calculateur (21) est positionné dans un compartiment de soufflante (111). Il est agencé pour déterminer, d'une part, une température dans la veine primaire (14) en fonction d'une tension entre les deux soudures froides et d'une température mesurée par le capteur de température de soudure froide (23) et, d'autre part, pour déterminer une anomalie de température dans le compartiment inter-veines (132) en fonction de la température mesurée par le capteur de température de soudure froide (23).The invention lies in the field of monitoring the condition of an aircraft and, more precisely, the condition of a turbojet fitted to the aircraft. It relates to a bypass turbojet (10) equipped with a system (30) for regulating the turbojet and for detecting a temperature anomaly in the inter-vein compartment. According to the invention, the regulation and detection system (30) comprises a thermocouple (22), a cold junction temperature sensor (23) and a computer (21), a hot junction (223) of the thermocouple (22) being positioned in a primary stream (14) of the turbojet engine and two cold welds (224, 225) of the thermocouple being positioned in an inter-stream compartment (132). The cold weld temperature sensor (23) is positioned in the intervein compartment (132) adjacent to the cold welds (224, 225). The computer (21) is positioned in a fan compartment (111). It is designed to determine, on the one hand, a temperature in the primary duct (14) as a function of a voltage between the two cold welds and of a temperature measured by the cold junction temperature sensor (23) and, on the other hand, to determine a temperature anomaly in the intervein compartment (132) as a function of the temperature measured by the cold junction temperature sensor (23).
