  • Patent number: 9523288
    Abstract: A hydraulic bearing is provided for a stationary gas turbine that has an oil sump with an outflow for hydraulic oil, wherein the outflow has an outflow opening which is arranged in the oil sump and an outflow line which is connected to the outflow opening. The hydraulic bearing is adapted to bring about an annular flow with a central air column when hydraulic oil flows out in the outflow line.

  • Patent number: 9234431
    Abstract: A seal assembly (50, 60) for a gas turbine engine for controlling air flow between a diffuser (48) and rotor disks comprising first and second annular flange ends (52, 54) and an annular seal mid-section (56) between and operatively connected to the flange ends (52, 54). The first and second annular flange ends (52, 54) abut respective outer frame members (46) of the diffuser, whereby a fluid flow path is formed between the seal assembly (50, 60) and the rotor disks (42). The first and second end flanges (52, 54) are composed of a material having a coefficient of thermal expansion that is substantially the same as a coefficient of thermal expansion of the material of the outer frame members (46). In addition, the material of the seal mid-section (56) has a coefficient of thermal expansion that is different than that of the materials of the annular flange ends (52, 54) and outer frame members (46).

  • Publication number: 20140301820
    Abstract: A turbine engine shutdown temperature control system configured to limit thermal gradients from being created within an outer casing surrounding a turbine blade assembly during shutdown of a gas turbine engine is disclosed. By reducing thermal gradients caused by hot air buoyancy within the mid-region cavities in the outer casing, arched and sway-back bending of the outer casing is prevented, thereby reducing the likelihood of blade tip rub, and potential blade damage, during a warm restart of the gas turbine engine. The turbine engine shutdown temperature control system may operate during the shutdown process where the rotor is still powered by combustion gases or during turning gear system operation after shutdown of the gas turbine engine, or both, to allow the outer casing to uniformly, from top to bottom, cool down.

  • Patent number: 8353445
    Abstract: Provided is a stackable storage and transport container for storing and for single-use or multiple-use transport of goods, especially small parts. The container is assembled from a foldable container blank having a bottom, two side walls foldable about a fold, two end walls foldable about a fold, and four corner flaps foldable inward against the side walls or end walls about a fold. Tabs are formed on the side walls and end walls such that they can fold laterally against the intermediate pieces. A stackable profile having a hook edge is placed about the upper edge to provide for the stacking of a number of containers. The container blank preferably is made of a plastic hollow sheet.

  • Publication number: 20110214431
    Abstract: A turbine guide vane support for an axial-flow gas turbine is provided. The support includes a tubular wall having an inflow-side end and an outflow-side end for a hot gas flowing in the interior of the turbine guide vane support in a flow path of the gas turbine. Cooling channels for a coolant are provided in the wall. The cooling channels extend from a coolant inlet to a coolant outlet, respectively. At least one of the cooling inlets and one of the cooling outlets, respectively, is disposed at the outflow-side end of the turbine guide vane support, wherein the cooling channel associated with the respective inlet and outlet extends up to the inflow-side end of the turbine guide vane support and transitions to a redirecting area from which the respective cooling channel further extends to the outflow-side end.
