Abstract
A new system is described that is able to detect mechanical failures in a rotating shaft or shafts such as those which may be found in an aircraft or other mechanical device or vehicle. The system comprises a first accelerometer provided on the rotating shaft to be monitored and a reference accelerometer provided elsewhere, and further comprising means for comparing information received from these accelerometers so as to determine a fault in the rotating shaft that is being monitored.
Claims15
A system for detecting a mechanical fault of a rotating shaft of a component;
- said system comprising:
- a first accelerometer configured to be connected to said rotating shaft of said component for obtaining first information relating to movement of the rotating shaft;
- and
- a second, reference accelerometer configured to be connected to said component at a location that is not on said rotating shaft, for obtaining second, reference information relating to said location that is not on said rotating shaft;
- and
- means for comparing said first information with said second information to detect said fault in said rotating shaft.
