摘要： A device for detecting a fault in a low-pressure fuel pump of a turbojet. The pump is driven by an accessory gearbox including a gear for mechanically driving the accessories. The device measures the vibration frequencies of the accessory gearbox and detects, from among the frequencies, at least one vibration frequency of the low-pressure fuel pump. The device allows a fault in the low-pressure fuel pump to be detected as soon as it occurs.

摘要： A method for monitoring plane engines The present invention relates to a method for monitoring engines of a plane comprising at least two engines (m1, m2, m3, m4), each engine (m1, m2, m3, m4) being controlled and monitored by an engine monitoring calculator (1, 2, 3, 4), said calculators (1, 2, 3, 4) being connected between them by a communication network (5) and each calculator (1, 2, 3, 4) monitoring the operating parameters (p, V) of the engine (m1, m2, m3, m4) it monitors. The method is characterized in that both calculators (1, 2, 3, 4) emit (60; 100) on the network (5) the value (V(k)) of at least one of said parameters (p(k)) for being compared (62; 102, 103, 104) with those (V(k′)) of the same parameter (p(k) p(k′)) emitted by the other calculator (1, 2, 3, 4), and in that, if a value (k)) deviates from the other (V(k′)) by a difference (d1(k), d2(k), d3(k)) higher than a predetermined threshold (S), one of the engines (m(k)) is diagnosed as being in an abnormal operation.
