20080232956 | Turbine Blade and Gas Turbine Equipped with a Turbine Blade - The invention relates to a turbine blade ( | 09-25-2008 |
20090016881 | TURBINE BLADE AND GAS TURBINE EQUIPPED WITH A TURBINE BLADE - The invention relates to a turbine blade comprising a vane that runs along a blade axis and a platform region, which is located at the root of the vane and has a platform that extends transversally to the blade axis. The aim of the invention is to guarantee the improved cooling of a platform region and the transition region from a turbine blade to a platform of a turbine blade, thus ensuring the cooling of the delimitation of a flow channel in a gas turbine. To achieve this, the platform comprises a first platform wall that does not support the vane and a second platform wall that supports said vane. According to the inventive concept, at the root of the vane and over the course of the transition region from the turbine blade to the platform, said first platform wall is aerodynamically curved and the course of the second platform wall has a receding shoulder in relation to the first platform wall, as a continuation of the vane. | 01-15-2009 |
20090220349 | Method for Producing a Gas Turbine Component Which is to be Coated, With Exposed Holes, Device for Carrying Out the Method, and Coatable Turbine Blade with Film Cooling Holes - There is described a method with which, on the basis of a three-dimensional recording of a component to be reworked, its surface configuration can be determined and stored temporarily so that, after it has been coated, it can be produced in its original surface form, or in its surface form then required, in certain regions, i.e. locally in the area of film-cooling openings. An especially precise and quick three-dimensional recording can be achieved by the use of the triangulation method. In this case, a reference pattern depicted on the component by a projector is recorded by two camera arranged at an angle. From the images from the cameras, the coordinates describing the surface three-dimensionally can then be determined by a control system using the triangulation method. | 09-03-2009 |
20090283508 | Method for producting a hole - A method for producing a hole with side-delimiting flanks in a component using a laser beam is provided. A laser beam is directed onto the component. A side flank of the hole is traced with the laser beam. A partial volume of the hole is formed by vaporizing the component material. This is repeated until the whole volume is formed. The laser beam may be oriented so that it includes an angle of more than 8° with the traced side flank. | 11-19-2009 |
20100008773 | Turbine blade and gas turbine equipped with a turbine blade - The invention relates to a turbine blade comprising a vane that runs along a blade axis and a platform region, located at the root of the vane having a platform that extends transversally to the blade axis. The aim of the invention is to configure a delimitation of a flow channel of a gas turbine in the simplest possible manner. Therefore, the platform is configured by an elastic sheet metal part that rests on the vane. Said part leads to a gas turbine comprising a flow conduit that runs along an axis of the gas turbine, said conduit having an annular cross-section for a working medium and a second vane stage that is situated downstream of a first vane stage, which runs along the axis. | 01-14-2010 |
20110176930 | Turbine vane for a gas turbine and casting core for the production of such - A turbine vane or blade including an interior structure is provided. In addition, turbulence elements connected directly upstream of openings disposed at the rear edge of the blade of the turbine vane or blade are also provided. These are disposed in a sequence, each having a flow side against which a coolant flows and which is at least partially arched in a concave manner. Preferably, the turbulence elements are configured in a crescent-shaped manner. This makes it possible to enlarge the openings without resulting in an increased consumption of coolant. A casting core is also provided. The openings required in the casting core for the production of the webs of a turbine vane or blade may now be placed at further distances than before. | 07-21-2011 |
20140097157 | COMBINED METHOD FOR DRILLING A LAYER SYSTEM, IN WHICH MECHANICAL WORKING AND EDM WORKING ARE PERFORMED - A method including mechanical removal and electrical discharge machining (EDM) working allowing symmetrical or asymmetrical holes to be produced with exact contours in a layer system including a metallic substrate and a non-metallic outermost layer is provided. In a first step, an outer region of the hole is worked by mechanical removal. In a final method step, when the underlying substrate or a metallic adhesion promoting layer has been reached an electrical discharge machining tool is used. | 04-10-2014 |
20140133956 | PROCESS FOR COOLING THE TURBINE STAGE AND GAS TURBINE HAVING A COOLED TURBINE STAGE - A gas turbine having a turbine stage is presented. The gas turbine has a guide vane that can be operated cooled by a cooling medium, and a cooling medium feed device for feeding the cooling medium into the interior of the guide van, which, in the region of its rear edge, has on the pressure side at least one cooling medium outlet opening, through which the cooling medium can flow out of the interior of the guide vane into the main flow. The cooling medium feed device has a mass flow control device for controlling the mass flow through the at least one cooling medium outlet opening, with which the mass flow through the at least one cooling medium outlet opening can be increased during operation of the gas turbine under part-load compared to operation of the gas turbine under full load. | 05-15-2014 |
