Heat Generation of Aircraft Tires at Landing

Abstract

Verbatim from Embry-Riddle Scholarly Commons. Not paraphrased, not summarized.

When the aircraft lands on a runway, the great speed difference between tires and runway causes non-negligible friction and speeds up wheels. The generated heat rapidly raises tire temperature and causes material decomposition, which leads to replacement cost and flight safety issues; the chemical substances in the air can also cause emission problems. Many studies on aircraft tire temperature are based on software simulation or experiments. The simulation result may be affected by unnecessary variables due to cumbersome modelling, and the observation result may be inaccurate due to a particularly dynamic friction process. On the other side, there are few theoretical calculations about it. Therefore, A dynamic and thermal MATLAB model based on Laplace's heat equation is developed in this study to simulate the tire friction and heat generation. The temperature rise can be treated as an indicator to predict wear under variable landing conditions. The model can also be used to develop tire wear prevention methods.
