Patent number: 10428664Abstract: A nozzle assembly for a gas turbine engine includes at least one pair of fixed vanes to define a nozzle between the pair of fixed vanes. The vanes can have an interior chamber defining a cooling circuit with a particle separator located within the interior chamber. The particle separator, which can comprise a virtual impactor, can have an accelerator for accelerating fluid moving through the virtual impactor such that the flow path is divided into a major flow moving into the interior chamber and a minor flow moving into a particle collector defined within the virtual impactor. The accelerator accelerates the fluid such that particles within the fluid are carried by their momentum into the particle collector with the minor flow, removing the particles from the major flow of fluid moving into the interior chamber.Type: GrantFiled: October 15, 2015Date of Patent: October 1, 2019Assignee: General Electric CompanyInventors: Hojjat Nasr, Ronald Scott Bunker, Gregory Michael Laskowski, Erich Alois Krammer

Patent number: 10245539Abstract: A filter system and method use a filter housing that defines an interior chamber and that includes an inlet opening extending into the interior chamber. The outer air flow housing has an outlet conduit through which a flow of air having particles is directed toward the inlet opening of the filter housing along a flow direction toward the interior chamber of the filter housing. The outer air flow housing engages the filter housing such that the filter housing is separated from the outer air flow housing along the flow direction to permit at least some of the air to pass around an exterior of the filter housing and exit the outer air flow housing while the particles in the at least some of the air pass into the interior chamber of the filter housing through the inlet opening.Type: GrantFiled: November 5, 2015Date of Patent: April 2, 2019Assignee: General Electric CompanyInventors: William Collins Vining, Robert Francis Manning, Victor Hugo Silva Correia, Corey Bourassa, Jared Peter Buhler, Hojjat Nasr

Patent number: 9988936Abstract: A shroud assembly for a gas turbine engine includes a shroud, hanger, and a hanger support mounted adjacent to a plurality of blades. The hanger can have an interior chamber defining a cooling circuit with a particle separator located within the interior chamber. The particle separator can have an inlet for accepting a flow of cooling fluid, such that a the flow of cooling fluid separates into a major flow and a minor flow carrying particles or particulate matter along the minor flow into a particle collector comprising at least a portion of the particle separator. Particles become constrained to the minor flow and pass into the particle collector, while the major flow is separated into the remaining area of the interior chamber to remove the particles from the flow of cooling fluid passing into the interior chamber.Type: GrantFiled: October 15, 2015Date of Patent: June 5, 2018Assignee: General Electric CompanyInventors: Hojjat Nasr, Gregory Michael Laskowski, Curtis Walton Stover, William Collins Vining

Publication number: 20170130651Abstract: A combustor for a gas turbine engine comprises a combustion liner to define a combustion chamber for burning fuel to drive to turbine. The combustion liner comprises a plurality of nugget holes for providing cooling fluid to create a cooling film over the surface of the combustion liner adjacent the combustion chamber. The nugget holes can be circumferentially angled relative to the engine centerline to provide the flow of cooling fluid in an angled manner to align with a local streamline for the flow of fluid from the combustor.Type: ApplicationFiled: November 6, 2015Publication date: May 11, 2017Inventors: Hojjat Nasr, Juntao Zhang, Jessica Erin Schladt, Craig Alan Gonyou
