1. A system for detecting torsional anomalies of an aircraft during a failure, the aircraft having a first drive shaft and a second drive shaft, the system comprising:

  • a grating, having;

    a plurality of teeth extending from the grating, the grating coupled to a first interconnection between the first drive shaft and the second drive shaft;

    a support bracket in close proximity to the first interconnection and positioned about the grating;

    a first sensor mounted on the support bracket;

    a second sensor mounted on the support bracket; and

    a processor comprising;

    a lookup table comprising;

    a plurality of spectral data of predetermined faults;

    the processor for comparing a spectral analysis of an output of the first sensor and second sensor to the lookup table;

    wherein the first sensor and second sensor are configured to detect the teeth of the grating.
