  • Circumferentially area ruled duct
    Patent number: 4677828
    Abstract: The area ruling of an annular diffuser disposed between the compressor and burner of a gas turbine engine is proportioned in a circumferential direction so that the maximum area ruling is adjacent the struts supporting the diffuser walls and the minimum is mid-way between the struts so as to achieve a substantial uniform velocity profile of the exiting air in the circumferential direction.
    Type: Grant

    Date of Patent: July 7, 1987
    Assignee: United Technologies Corporation
    Inventors: John A. Matthews, Edmund E. Striebel, Domingo Sepulveda, Francis C. Pane, Jr.
  • Method of distributing fuel flow to an annular burner for starting of a gas turbine engine
    Patent number: 4548032
    Abstract: Improvement to the starting characteristics of an annular combustor for a gas turbine engine that employs dual fuel nozzles (primary and secondary fuel flow systems) by redistributing the total fuel admitted to the nozzles in an asymmetrical pattern to deliver the requisite amount of fuel to the igniter by the primary flow system feeding fuel to that igniter.
    Type: Grant
    Filed: July 25, 1983
    Date of Patent: October 22, 1985
    Assignee: United Technologies Corporation
    Inventors: Domingo Sepulveda, Edmund E. Striebel
  • High blockage diffuser with means for minimizing wakes
    Patent number: 4512158
    Abstract: This invention minimizes wakes manifested by a fuel nozzle support structure extending through an annular diffuser engine to the burner in a gas turbine engine, spaced walls extending from the inner and outer wall of the diffuser project toward the nozzle support downstream of the support that passes transverse to the flow, one wall being shaped conically and the other being shaped bell-mouthed and convergent.

  • Louver construction for liner of gas turbine engine combustor
    Patent number: 4184326
    Abstract: This invention relates to an improved combustor liner for a gas turbine power plant which liner is constructed from a plurality of louvers that include a lip and cooling means for defining a cooling film of air flow adjacent the liner. Means are provided for preventing lip closure which in turn is detrimental to film cooling.
