Claim Text:
1. A method of estimating health of aircraft brake system friction material, comprising the steps of: sensing a temperature of the friction material; supplying the sensed temperature to a processor-implemented thermal model, the processor-implemented thermal model configured to estimate friction material temperatures at one or more locations on the friction material; supplying the estimates of friction material temperatures to a processor-implemented thermal oxidation model, the processor-implemented thermal oxidation model configured, based on the estimates of friction material temperatures, to estimate friction material loss due to thermal oxidation; supplying data representative of runway fluid exposure to a processor-implemented catalytic oxidation model, the processor-implemented catalytic oxidation model configured, based on the runway fluid exposure, to estimate friction material loss due to catalytic oxidation; and estimating the health of the friction material based on the estimates of friction material loss from the processor-implemented thermal oxidation model and the processor-implemented catalytic oxidation model.
