1. A method of analyzing a turbine engine to determine a normal engine condition or a faulty engine condition, said method comprising the steps of:

  • acquiring at least one engine operating parameter;

    calculating at least one engine residual value from said at least one engine operating parameter;

    normalizing said at least one engine residual value to yield at least one normalized engine residual;

    mapping, via a clustering technique, said at least one normalized engine residual as at least one input vector into an engine condition space having a plurality of clusters, each of said plurality of clusters representing either a normal vector engine condition or a faulty vector engine condition;

    identifying a closest cluster within said engine condition space, said closest cluster being closer to said at least one input vector than any other of said plurality of clusters; and

    determining a normal engine condition for the engine undergoing analysis if said closest cluster represents a normal vector engine condition, and determining a faulty engine condition for the engine undergoing analysis if said closest cluster represents a faulty vector engine condition.
