Experimental Identification of the Thermal Parameters of an Aircraft Braking System During the Braking Phase

Abstract

This paper concerns the modelling of the thermal evolution of a multi-disc aircraft brake during the aircraft’s stopping phase. An experimental set up using flywheels to simulate realistic aircraft braking is used to measure temperatures in the different components of the system using thermocouples. Therefore, based on the measurements taken under these experimental conditions, the heat fluxes due to the friction dissipation have been identified.Based on the identified heat fluxes at the interfaces, the calculated temperatures are in accordance with the measurements taken on the experimental test bench. Furthermore, the determined parameter values exhibit physical consistency. The heat energy that has been identified corresponds to the level of mechanical energy degradation measured during different tests, thus affirming the validity of the obtained results.
