  • Diffuser having shaped vanes
    Patent number: 10352237
    Abstract: A radial diffuser and method for manufacturing a radial diffuser is provided, where the diffuser includes a vane positioned between a hub and a case. The hub includes a surface. The vane projects from the surface of the hub and is wedge-shaped. The vane includes a leading end extending toward a radial inner edge of the hub, a trailing end extending toward a radial outer edge of the hub, an upper surface, first and second sides extending longitudinally along the vane, and a middle region disposed between the hub and the upper surface. The vane at the upper surface has a thickness defined by a first wedge angle at the upper surface. The vane at the middle region has a thickness defined by a second wedge angle at the middle region. The second wedge angle is smaller than the first wedge angle.
