The paper presents an application of a compliant foil bearing for estimation of the thrust force in the single stage radial blower under operational conditions. The bump foil of the thrust bearing behaves as a nonlinear spring. The knowledge of the spring deflection curve allows one to estimate the actual thrust force for a measured bump deflection at the given rotational speed. To acquire the deflection curve, static calibration of the axial shaft displacement sensor was performed. During the calibration, the information about voltage signals of the sensor for the given loading force was gathered. Then, the measured voltage values at different speeds and loads were recalculated to the thrust force. The results were verified by a comparison to the thrust force resulting from the pressure distribution on the impeller.
