  • Patent number: 10967964
    Abstract: The ‘Air Wheel’ rotor is a variable pitch rotor with variable twist blades. The ‘Air Wheel’ rotor comprises a closed wing coupled to one or more coaxial hubs via torsional elastic blades, the blades are coupled to the closed wing in one of the following ways: rigid, elastic, or visco-elastic. There is provided a wide range of combinations of the wing relative width and coning angle typical for a lifting rotor with a thin planar wing attached to the tips of long blades, for a shrouded fan in a wide annular wing, or for an impeller in a rotating cylindrical wing. The ‘Air Wheel’ rotor combines and enhances the advantages of a rotor and a wing, it has excellent aerodynamic characteristics, and eliminates limitations of the rotor size and flight speed. The ‘Air Wheel’ rotor can be used for designing vertical take-off and landing aircraft. The “Air Wheel” rotor is universal and can function as a lifting rotor, or a wind turbine, or an aircraft propeller, or a marine propeller.

  • Patent number: 10968918
    Abstract: Wear rings for electric submersible pump (ESP) stages are provided. An example ESP has one or more running clearance seals reinforced with high-hardness wear rings. Ceramics and carbides may provide the high hardness for the wear rings, but such substances are more brittle than metals and have different coefficients of thermal expansion than metals. For protection, each high-hardness wear ring may be mounted with an elastic cushioning scheme. The elastic mounting preserves each wear ring from shock, stress, and breakage from thermal expansion and contraction of an adjacent pump part. Each high-hardness wear ring may also have a low-stress driving mechanism that cushions the rotational force imparted to the wear ring when the ESP pump is being powered. In some implementations, the elastic mounting scheme may also serve as the low-stress driving mechanism for the high-hardness wear ring.

  • Patent number: 10927889
    Abstract: Disclosed is an embodiment of a turbocharger roller support system that utilizes roller-shaft interfaces that are slanted to locate a turbocharger shaft with a turbine and compressor. Slanted contact surfaces on the turbocharger shaft are slanted inwardly so that the turbo shaft remains centered in the roller support system. The rollers entirely locate the turbocharger shaft, so that no bearings are necessary directly on the turbocharger shaft. The rollers spin at a slower speed than the turbocharger shaft, so can utilize lower speed bearings.
