1. An erosion detection system for detecting erosion in blades in a turbine engine, the erosion detection system comprising:

  • a sensor data processor, the sensor data processor adapted to receive engine sensor data from the turbine engine and generate sensor data residuals and sensor data residual slopes from the sensor data; and

    a cluster analysis mechanism, the cluster analysis mechanism adapted to perform a cluster analysis on the sensor data residuals and sensor data residual slopes using a first Gaussian density function representing a good turbine blade cluster and a second Gaussian density function representing an eroded turbine blade cluster to determine a likelihood that erosion has occurred in the blades.
