Publication number: 20080136324Abstract: There is described an arrangement comprising at least one luminescent heat insulating layer which is disposed on a carrier body, for preventing heat transfer between the carrier body and the surrounding area of the carrier body. The heat insulating layer comprises at least one luminous substance which can be excited, with the aid of an excitation light having a determined excitation wave length for emitting a luminescent light having a determined luminescent wave length. At least one additional heat insulating layer, which is essentially free from the luminous substance, is provided. The additional heat insulating layer is essentially opaque to the excitation light in order to excite the emission of luminous light and/or for the luminous light of the luminescent substance.Type: ApplicationFiled: October 25, 2005Publication date: June 12, 2008Applicant: SIEMENS AKTIENGESELLSCHAFTInventors: Ulrich Bast, Wolfgang Rossner

Patent number: 7229254Abstract: The invention relates to a turbine comprising at least four stages and to the use of a rotor blade with a reduced mass. In prior art, rotor blades in the fourth stage of a gas turbine, which exceed 50 cm in length, cause problems relating to mechanical strength, as centrifugal forces of too great a magnitude occur during the rotation of the rotor blades. An inventive rotor blade in the fourth row of a gas turbine has a reduced density as a result of a high proportion of a ceramic, thus reducing the centrifugal force.Type: GrantFiled: December 18, 2002Date of Patent: June 12, 2007Assignee: Siemens AktiengesellschaftInventors: Ulrich Bast, Wolfgang Hermann

Patent number: 7141990Abstract: An apparatus for monitoring the structural integrity of a component. A monitoring structure is applied to a component that is subject to structural degradation. The monitoring structure includes an electrical conductor that becomes cracked if the component becomes structurally degraded. When the component is a ductile metal component that may be degraded by bending, the electrical conductor is formed of a brittle material that cracks when the ductile metal component is bent. When the component is a brittle ceramic heat shield wherein a crack having a critical length is of concern, the electrical conductor is located at a predetermined location wherein a critical length crack in the component will propagate into the conductor. A crack in the electrical conductor is detected with a monitoring device to indicate a degraded structural condition in the component.Type: GrantFiled: May 22, 2003Date of Patent: November 28, 2006Assignee: Siemens AktiengesellschaftInventors: Ulrich Bast, Stefan Lampenscherf, Uwe Rettig

Publication number: 20060177665Abstract: An arrangement of at least one heat-insulation layer for a carrier body for preventing heat transfer between the body and a surrounding area includes at least one type of luminous substance which is excitable by an excitation light having a determined excitation wavelength for emitting a luminescent light having a defined emission wavelength and at least a second heat-insulation layer substantially free of the luminous substance. The second heat-insulation layer is opaque with respect to the excitation light used for initiating the luminescent light emission and/or to a luminous substance light. The luminous substance contains at least one type of mixed oxide selected from a perovskite group of total formula AA?O3, and/or of pyrochlore of total formula A2B2O7, wherein A and A? is the trivalent metal, respectively and B is a tetravalent metal.Type: ApplicationFiled: July 28, 2004Publication date: August 10, 2006Applicant: SIEMENS AKTIENGESELLSCHAFTInventors: Ulrich Bast, Wolfgang Rossner

Publication number: 20060177676Abstract: A heat-insulation material for a heat-insulation layer (3) for a carrier body (2) for preventing heat transfer between the carrier body and a surrounding area (7) therearound includes at least one luminous substance which is excitable for emitting luminescent light having a defined emission wavelength and includes at least one type of metal oxide containing at least one trivalent metal (A). Also described is an arrangement of at least one heat-insulation layer which contains the heat-insulation material and is applied to the carrier body. The described heat-insulation material is characterised in that the metal oxide is embodied in the form of a mixed oxide selected in a perovskite group of total formula AA?O3, and/or of pyrochlore of total formula A2B2O7, wherein A? is the trivalent metal and B is a tetravalent metal. The heat-insulation layer containing the heat-insulation material is preferably used for a gas turbine.Type: ApplicationFiled: July 28, 2004Publication date: August 10, 2006Inventors: Ulrich Bast, Wolfgang Rossner

Publication number: 20050229847Abstract: A method and device for layer thickness determination allows for the layer thickness to be determined in situ during the coating process. This is achieved using a sensor which has an electrical property which, as a result of the coating process, changes in a manner which is representative of the layer thickness which has been reached. As such, this property can be measured.Type: ApplicationFiled: May 12, 2005Publication date: October 20, 2005Inventors: Ulrich Bast, Roman Beyer, Ralph Reiche

Publication number: 20050212535Abstract: The invention relates to an assembly that consists of a structural element and at least one control element for detecting degradation of said structural element. Said control element comprises an electroconducting control structure that is decoupled from a functionality of the structural element and that has a defined electrical property. The control structure and the structural element are firmly interlinked to such an extent that the degradation of the structural element effects a degradation of the control structure and thus a change of the defined electrical property of the control structure. The structural element is for example a ceramic heat shield of a combustion chamber of a gas turbine. The control structure consists of a brittle ceramic conductor material.Type: ApplicationFiled: May 22, 2003Publication date: September 29, 2005Inventors: Ulrich Bast, Stefan Lampenscherf, Uwe Rettig
