Abstract : The occupation with tribology in aviation in important for the future. To confirm this statement, at first the historical origin of the name tribology is outlined as a last step in an interdisciplinary approach, a linking concept, in the field of phenomena of friction of solids in relative motion. For a further confinement on tribology in aviation, the trends in this area for the next two decades are reviewed: reduction of maintenance, further improvement of the ratio of specific output to weight, reduction of maintenance, further improvement of safety. Then the consequence from these trends are outlined with respect to research in tribology. The current status of research is sketched and some unsolved problems are discussed, e.g. interaction of material/lubricant in areas of mixed friction (reaction layers), interaction of material/lubricant in the hydrodynamic region concerning fatigue and concerning friction, friction and wear of synthetic bearings with and without lubrication, friction, wear and service time if solid lubricants are used, topographical features of surfaces. An outlook closes the paper with an appeal for early interdisciplinary government sponsored research to gain the wide spread of basic knowledge necessary for new and better solutions.
