Sliding Power in Aircraft Landing

Abstract—This paper addresses what happens during the acceleration period of undercarriage wheels after aircraft touchdown on the runway. In this acceleration period, a sliding between the wheel tyre and runway surface takes place. The sliding friction causes high temperature which emits pollution smoke and produces excessive tyre wear. A model based on mechanical dynamics is established for analysing the high temperature, heat transfer rate to tyre and concrete runway. The effect of designing a pre-rotation device is also included in order to lower the temperature and reduce the tyre wear. The width of tyre is shown also having effect on the raised temperature. A blackened runway is believed to have changed the heat conduction therefore affecting the landing quality.
