  • Fuel nozzle for gas turbine engine
    Patent number: 4946105
    Abstract: Fuel nozzle 10 has fuel delivery through circumferentially spaced orifices 34 impinging on baffle 40. Fuel flows through a restricted annulus 42 to an expansion volume 50 and thence through a restricted frusto conical annulus 52 to discharge 16. The baffle, restriction and expansion spreads the discrete flows through each orifice to obtain uniform circumferential expansion.

    Inventors: Francis C. Pane, Jr., James A. Dierberger
  • Airblast fuel injector
    Patent number: 4773596
    Abstract: A fuel injector assembly for a gas turbine combustor projects a hollow conical spray of fuel. A plurality of discrete surrounding air nozzles 42 project air directly toward the axis 46 of the injector at an angle of 15 degrees, establishing a fuel rich external recirculation zone 52.

  • 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.

  • Fuel nozzle for gas turbine engine
    Patent number: 4609150
    Abstract: A fuel nozzle for a gas turbine engine is constructed with two major castings where one is the support and the other is the head, both welded together adjacent the fuel orifice plate. The fuel passage is cast into the support providing a smooth radius from the radial to axial flow path and a smooth transition from the circular to the annular cross section. This configuration allows dimension control over the filming lip and other critical dimensions of the nozzle.

  • 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.

  • Fuel nozzle for gas turbine engine
    Patent number: 4418543
    Abstract: A fuel nozzle designed to reduce pollutant emissions and minimize the buildup of coke in the secondary fuel passage of a dual orifice fuel nozzle for the combustor of a gas turbine engine sizes the orifices and passages of the air and fuel so as to increase the pressure in the secondary passage during its inoperative mode and when the primary fuel passage is in the operative mode and having the air and fuel issuing from both the primary and secondary orifices swirl in the same direction.

  • Fuel nozzles with water injection for gas turbine engines
    Patent number: 4395874
    Abstract: A pressure atomizing fuel nozzle of the type that has a primary and secondary fuel system for a gas turbine engine and includes air swirl means and water injection is designed so that the water laden airstream is swirling in the same direction as both the fuels egressing from the primary fuel system and the secondary fuel system.

  • Anti-coke fuel nozzle
    Patent number: 4362022
    Abstract: Coke hereinbefore known to form in the secondary passage of a dual orifice fuel nozzle for the combustor of a turbine type power plant is prevented from forming by imposing increased air pressure in the secondary passage during its inoperative mode and when the primary fuel passage is in the operative mode, without relying on purging or requiring an external air source.

  • 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.
