  • Doubled bowed compressor airfoil
    Patent number: 6331100
    Abstract: A compressor airfoil includes pressure and suction sides extending from root to tip and between leading and trailing edges. Transverse sections have respective chords and camber lines. Centers of gravity of the sections are aligned along a double bowed stacking axis for improving performance.
    Type: Grant
    Filed: December 6, 1999

  • Gas turbine engine variable bleed pivotal flow splitter
    Patent number: 5279109
    Abstract: The present invention provides a gas turbine engine with a circumferentially disposed plurality of pivotal flow splitters between compressor sections to bleed off flow and remove particles, particularly ice in the case of an aircraft fan-jet gas turbine engine, by pivoting the leading edge of the splitter into the compressor flow thereby using the total pressure Q of the flow to drive bleed flows overboard and remove particles.
    Type: Grant

    Inventors: Hsin-Tuan Liu, William R. Hines
  • Crossover duct
    Patent number: 4344737
    Abstract: A crossover duct for providing flow communication between multiple stages of centrifugal compressors and the like. The duct forms a continuous annular path between compressor stages for turning radially outward gas flow to a radially inward direction. The duct includes thin diffuser vanes having aerodynamically contoured leading edges, and a vaneless turning bend having a generally elliptical wall geometry.
    Type: Grant

  • Crossover duct assembly
    Patent number: 4251183
    Abstract: A crossover duct assembly for providing flow communication between multiple stages of centrifugal compressors and the like. The duct assembly includes inner and outer wall sections forming a continuous annular flow path between compressor stages for turning radially outward gas flow to a radially inward direction. The duct includes a thin vane diffuser section, a vaneless turning bend having an elongated wall geometry, and a deswirl vane section for enhancing smooth gas flow with minimum pressure loss.
