  • Patent number: 11946392
    Abstract: A flow control device for constraining fluid flow between axial flow turbomachines in series has a flow constrainer which constrains the fluid flow downstream of the first turbomachine in the series to the blades region of the second turbomachine, preventing fluid flow from impacting the hub or nosecone of the second turbomachine and providing more uniform fluid flow to the second turbomachine. The flow control device includes connective elements for positioning between the downstream region of the first turbomachine and the upstream region of the second turbomachine. The device may be equipped with stator vanes having a variety of optional configurations to further improve the uniformity of the fluid flow load on the second turbomachine.
    Type: Grant

  • Patent number: 10109970
    Abstract: The disclosed invention is a slip ring assembly that provides electrical power transfer to centrifugal turbomachinery while minimizing or eliminating the presence of wires in the flow path. The device transfers electrical power through a set of wires connected to a plurality of brushes that are held rotationally stationary, but allowed to displace axially or radially through a set of springs. The brushes make contact with conductive busbar rings, transferring electricity to the busbar rings. The busbar rings rotate with the centrifugal turbomachine with a set of wires that connect the busbar rings to the blades or other aerodynamic surfaces of the centrifugal turbomachine.
