Magnetic thrust bearing systems are disclosed. Examples disclosed herein include a thrust bearing system comprising a thrust disc protruding radially outward from a shaft, the thrust disc including a first magnet, the first magnet including a first pole at a forward side of the thrust disc and a second pole at an aft side, a first thrust pad positioned on the forward side, the first thrust pad including a second magnet adjacent to a first surface of the first thrust pad, the first surface facing the thrust disc, the second magnet including a third pole, the third and first pole having the same polarity, and a second thrust pad including a third magnet adjacent to a second surface of the second thrust pad, the second surface facing the thrust disc, the third magnet including a fourth pole, the fourth and second pole having the same polarity.

Systems and techniques that facilitate detecting fuel in oil, lube degradation, and foreign object contamination through optical and/or color characterization are provided. A signature component can generate a digital signature corresponding to a lubricant in a lubrication circuit of an engine. The digital signature can be based on optical or visual properties of a sensor array coupled to the lubrication circuit and exposed to the lubricant, wherein the optical or visual properties of the sensor array can depend on a health of the lubricant. An analysis component can characterize the health of the lubricant by comparing, via a machine learning algorithm, the digital signature with a baseline digital signature corresponding to a desired health-level of the lubricant. In some embodiments, a light emitter component can emit a first light onto the sensor array, and a light receiver component can receive a second light emitted by the sensor array in response to the first light. The signature component can then generate the digital signature based on the first light and the second light. In some embodiments, an image capture component can capture an image of the sensor array. The signature component can then generate the digital signature based on the captured image.
