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.

Device and method for detecting a fault in a low-pressure fuel pump of a turbojet and turbojet including one such device

A device and method for monitoring a high-pressure pump in a turbomachine fuel supply circuit by detecting opening of a pressurizing and shut-off valve mounted on an outlet side of a fuel flow regulating valve, by measuring rotational speed of the turbomachine corresponding to the opening of the pressurizing and cut-off valve, and by monitoring change in a value of the rotational speed to propose replacement of the high-pressure pump when the measure value rotational speed reaches a predetermined threshold.

Monitoring of a high-pressure pump in a turbine engine fuel supply circuit

A method for monitoring engines of a plane, including at least two engines, each engine being controlled and monitored by an engine monitoring calculator, the calculators being connected to each other by a communication network and each calculator monitoring operating parameters of one engine. The method being characterized in that both calculators output on the network the value of at least one of the parameters for comparison with the same parameter outputted by the other calculator, and if a value of one calculator deviates from a value of the other calculator by a difference higher than a predetermined threshold, one of the engines is diagnosed as operating abnormally.
