1. A method of estimating fatigue life of a structure, comprising:

  • determining strain on the structure using a plurality of gauges positioned on the structure;

    detecting a parameter of the structure with a plurality of sensors positioned on the structure;

    converting the detected parameter and the determined strain to proportional loads acting on the structure;

    transforming the proportional loads to coordinate system data associated with the structure; and

    estimating a fatigue life of the structure based on the coordinate system data.
