ASLL / aerostatic air bearing

Project target:

01.04.2018 – 30.09.2020


Project partner:

  • Lehrstuhl für Strömungs- u. Arbeitsmaschinen (SAM) der TU Kaiserslautern (TUK)


Development of an aerostatic air bearing system using fiber-reinforced ceramic for application in a turbomachinery.

The fiber-reinforced ceramic material (CMC – Ceramic Matrix Composite) was developed by the DLR-institute in Stuttgart/Germany. For this project the CMC material will be provided by DLR with different dimensions and porosities.

Following advantages over conventional bearing systems are expected:

  • oil-free- and lubrication-free bearing system
  • capability for high rotation speed (w/ sufficient damping behaviors)
  • low frictional power level
  • robust and maintenance-free
  • low sound pressure level
