Edmund E. Striebel has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • 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.
    Type: Grant
    Filed: April 6, 1987
    Date of Patent: September 27, 1988
    Assignee: United Technologies Corporation
    Inventors: Richard R. Wright, Francis C. Pane, Jr., John A. Matthews, Edmund E. Striebel
  • 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
    Filed: November 13, 1984
    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.

  • 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.
