INVESTIGATING TYRE SURFACE TEMPERATURE AT TOUCHDOWN WITH PRE-ROTATION

Abstract: This project investigates the changes in tyre surface temperature during aircraft touchdown when pre-rotation is applied to the landing gear. During the landing phase, tyres undergo rapid temperature fluctuations due to the sudden interaction with the runway, which can affect tyre performance, longevity, and safety. Pre-rotation involves rotating the tyres before touchdown to reduce the relative speed between the tyre and the runway, potentially minimizing the thermal shock upon initial contact. The project aims to analyse how pre-rotation influences the temperature distribution across the tyre surface at touchdown, by using experimental method. The results will help to identify the potential benefits of incorporating pre-rotation into landing procedures, providing insights into improved tyre durability, enhanced safety, and more efficient landing dynamics.
