Design and Development of a High Efficiency Air Turbine

Jun 07, 2019· Figure 11 shows the power output of the turbine and frictional power consumption of the spindle bearings over a range of speeds. The friction power of the spindle bearings is clearly quite significant, consuming over 40 W of power at 90,000 rpm. This is likely due to the large increase in bearing preload at high speeds.
