| Research Abstract |
In order to realize aerodynamic bearings which can stably operate at more than 1Mrpm, we proposed new-type aerodynamic foil journal bearings. We investigated the high-speed stability of the proposed foil bearings, and it was confirmed that the rotor supported by the proposed foil bearings can rotate at more than 700krpm. In addition, The foil thrust bearing was manufactured and we investigated the static characteristics of the foil thrust bearing. As a result, we confirmed that the foil thrust bearing has the maximum load capacity of 4.9N at 350krpm.
