Abstract: In this work, the authors tackle the problem of
laboratory simulation of frictional contact in wheels-up emergency
landing conditions. To design a novel tribometer simulating the contact
between an aircraft structure and a runway, one must carry two
complementary main tasks: the understanding of the underlying physical
mechanisms and the scaling up of the in-lab results to the scale of
interest. The authors propose to progress on the first task by
conducting exploratory work using existing resources. Their contribution
consists of a multi-scale methodology to reconstruct the wear process in
a tribological system within wheels-up emergency landing conditions.
This could provide guidance for safer aircraft and runway design. The
study falls within the framework of three-body tribology. The proposed
multi-scale characterisation methodology is made up of four steps. After
describing the whole tribological system, its mechanical response is
measured and analysed. This measurement is complemented by surface
observations and physicochemical analyses. Finally, all the measurements
and observations are discussed to come across a phenomenological wear
scenario that revealed friction and wear as system responses with the
key role of the third body.
Keywords: emergency landings, high-energy friction,
pad-on-disc, wear, third body, multi-scale.
