Özet

For a multiple carbon-carbon composite aircraft disk brake system, a transient heat transfer analysis is numerically carried out using temperature-dependent thermophysical properties. Operations of the antiskid control brake system are simulated by considering variations of pressure and angular speed during the braking action. The heat developed during that process is assumed to be convectively released. Maximum temperatures are found to occur around the middle disk and on the disk mid-radii. Maximum and minimum temperature differences amounting to 350 degrees C are found to occur inside the brake assembly.
