Abstract
A method to and an apparatus including a processor configured to determine a mass parameter indicative of a mass of an aircraft brake assembly, the mass parameter determined using an estimated amount of energy absorbed by the brake assembly in a given period of time and a corresponding estimated change in temperature of the brake assembly. Also disclosed is a non-transitory computer readable storage medium having stored thereon instructions which when executed by a processor, cause the processor to perform the method.
Claims20
A system comprising:
- temperature sensor configured to sense a temperature of an aircraft brake assembly on an aircraft and output temperature data indicative of the sensed temperature, wherein the temperature sensor is mounted to a brake disc in the aircraft brake assembly and the aircraft includes a plurality of braking modes;
- and
- a processor configured to:
- receive the temperature data,
- use the temperate data to estimate a change in temperature of the aircraft brake assembly,
- repeatedly determine a mass parameter indicative of a mass of the aircraft brake assembly, the mass parameter is determined using an estimated amount of energy absorbed by the brake assembly in a given period of time and the estimated change in temperature of the brake assembly,
- store each of the mass parameters and a point in time corresponding to the mass parameter,
- determine a trend in the mass parameters of the brake assembly over the period, wherein the determination of the trend is based on the stored mass parameters and points in time, and
- select a braking mode from the plurality of braking modes based on the trend in the mass parameters.
