| 20090189557 | METHOD AND ARRANGEMENT FOR CONTROLLING AN ELECTRIC DRIVE - A method for controlling an electric drive is proposed, in which, in the event of a fault, a motor control unit of an electric motor implements a safety measure to change over to a secure operating condition, such that when a faulty three-phase current feed to the electric motor is detected, a fault-associated operating mode is activated. In addition, an arrangement for controlling an electric drive comprising an electric motor with a motor control unit is proposed, which implements a safety measure in the event of a fault so as to change over to a secure operating condition, such that when a faulty three-phase current feed to the electric motor is detected, the motor control unit activates a fault-associated operating mode. | 07-30-2009 |
| 20100019741 | CIRCUIT ARRANGEMENT AND METHOD FOR REGULATING THE CURRENT IN AN ON-BOARD ELECTRICAL POWER SUPPLY SYSTEM OF A VEHICLE - A circuit arrangement for regulating the current in an on-board electric power supply system of a vehicle, with a controllable damping resistance, an energy accumulator and an electronic control unit. The damping resistance is adjustable to satisfy a control condition, such that generator current flowing through the control unit can be compensated by a counter-current originating from the energy accumulator and flowing through the damping resistance, having regard to a specified current limit value. In a method for controlling the circuit arrangement, generator current flowing through the control unit is compensated by a counter-current originating from the energy accumulator and flowing through the damping resistance, and the damping resistance is controlled, in such a manner, that a predetermined current limit value is taken into account. | 01-28-2010 |

| 20080201947 | Method For Repairing Turbo Machine Blades - A method is for repairing turbo machine blades, e.g., gas turbine blades on integrally bladed gas turbine rotors. The method includes at least the following steps: a) providing a turbo machine blade to be repaired or an integrally bladed rotor to be repaired having a damaged blade section; b) removing the damaged blade section from the turbo machine blade or from the integrally bladed rotor resulting in a blade stump; c) clamping the blade stump at least in the region of a flow leading edge and a flow trailing edge of the same in a cooling device; d) applying respectively a punctiform welding bead in the region of the flow leading edge and a flow trailing edge of the blade stump by laser powder build-up welding, the welding beads protruding at least over the flow leading edge and the flow trailing edge; e) applying material by laser powder build-up welding between the welding beads in the region of the or each removed blade section for restoring the respective blade section. | 08-28-2008 |
| 20100028158 | HIGH-PRESSURE TURBINE BLADE AND PROCEDURE FOR REPAIR OF HIGH-PRESSURE TURBINE BLADES - The invention relates to a procedure for repair of high pressure turbine blades of an aircraft engine, with the steps: —separating a damaged section of the high pressure turbine blade; and—generating a section to replace the separated section on or upon the high pressure turbine blade by means of laser beam generation from the powder bed, as well as a high pressure turbine blade. | 02-04-2010 |
| 20100074755 | METHOD FOR REPAIRING TURBINE BLADES - A method for repairing turbine blades by replacing at least a part of the blade profile, the method having: a) manufacture of a replacement blade part; b) separation of the damaged area with a standardized cutting plane, leaving behind a remaining blade; c) matching of the replacement blade part to the actual geometry of the remaining blade; d) connecting or joining of the replacement blade part to the remaining blade by soldering of at least one web and welding of an outer contour. | 03-25-2010 |
| 20100151145 | DEVICE AND METHOD FOR THE REPAIR OR PRODUCTION OF BLADE TIPS OF BLADES OF A GAS TURBINE, IN PARTICULAR OF AN AIRCRAFT ENGINE - The invention relates to a device for the production or repair of a blade for a gas turbine, said device comprising: a holding device for holding a blade or an aerofoil of a blade; a lowering mechanism for lowering the blade or the aerofoil; a container for receiving power and/or for receiving the blade or the aerofoil; a heating device; and a radiation source, wherein the heating device is formed as an induction coil. | 06-17-2010 |
| 20100284817 | METHOD FOR PRODUCING A BLISK OR A BLING, COMPONENT PRODUCED THEREWITH AND TURBINE BLADE - A method for producing a blisk (bladed disk) or a bling (bladed ring) of a gas turbine is disclosed. The method includes the following steps: a) producing a turbine blade by joining a blade to an adapter element consisting of a metal material that is suitable for fusion welding, the adapter element being used to form a blade root of the turbine blade, and b) joining the turbine blade to a rotor disk consisting of a metal material that is suitable for fusion welding or to a rotor ring consisting of a metal material that is suitable for fusion welding in such a manner that the turbine blade is arranged on the outer periphery of the rotor disk or of the rotor ring.
