The invention relates to a redundant electrical machine for driving a propulsion means at an increased level of operational safety. The machine comprises, for example, two systems consisting in each case of a stator winding system and a rotor, which is assigned thereto and has permanent magnets, the rotors being fastened to a common shaft for driving the propulsion means. If a defect occurs in one of the stator winding systems, the rotor, which continues to rotate, has to be prevented from inducing electrical voltages in this stator winding system, since this can lead to a fire in the machine. Therefore, a demagnetisation device is provided, which brings about targeted demagnetisation of the permanent magnets of the rotor that is assigned to the defective stator winding system, and so the induction of electrical voltages is prohibited.

A gas turbine combustor assembly with a trapped vortex feature A combustor assembly (100) of a gas turbine engine (10) having a trapped vortex feature to reduce emissions is presented. The trapped vortex is formed using ammonia injected into an annular cavity (60) located in a wall surrounding a combustion chamber (28) of the combustor assembly. The annular cavity (60), and therefore the trapped vortex, is positioned such that when the combustion occurs within the combustion chamber the position of the annular cavity, and therefore of the trapped vortex, is downstream of a flame front (9). The emissions resulting from combustion travel through the combustion chamber (28) and pass by the annular cavity (60) before exiting the combustion chamber. The trapped vortex in the combustion chamber supplies NH2radicals, resulting from the ammonia of the trapped vortex, to the passing by emissions and converts NOx and/or N20 in the emissions to non-polluting products, mainly water and nitrogen.

The invention relates to a burner tip (19), suitable for use in a pilot burner, e.g. in a gas turbine. The invention further relates to a method for producing the burner tip (19) by an additive production process such as selective laser melting. According to the invention, a part of the wall (25) of the burner tip (19) is made porous with pores or as a space grid, wherein the air can be transported from the air duct through the intermediate spaces in the space grid or the open pores. In this way, the air can cool the material of the burner tip (19) which results in a lesser thermal load. The wall structure (25) can be built up in multiple layers (26, 27, 28) of differing porosity or with a differing grid structure.

An end or intermediate casing for a combustion turbine engines includes prefabricated vanes of a first metal. Ends of the prefabricated vanes are then embedded within cast-in place inner and outer, annular-shaped ring castings, formed from a second metal having a lower melting point than the first metal. The respective ends of the prefabricated vanes include first and second shanks, with respective first and second surface features that are oriented transverse to the central axis of the vane are encapsulated in the molten second metal during the inner and outer ring casting. Once the castings harden, the first and second surface features, such as for example circumferential fillets projecting outwardly from the airfoil portion of the vane, inhibit separation of the vanes from the respective inner and outer rings.

The aim of the invention is to create an electrical appliance (2) that can be connected to a high-voltage network in a flexible and cost-effective manner. To this end, a device (1) with a housing (12) filled with an insulating fluid is provided, a high-voltage bushing (16) comprising a high-voltage conductor (15) extending through a bushing insulator (17) being fixed to the housing (12). A cable connection (9) is also provided on the housing (12) in order to connect a high-voltage cable (8). In the housing (12), a jumper (14) surrounded by the insulating liquid produces a direct electrical connection between the cable connection (9) and the high-voltage conductor (15) of the high-voltage bushing (16). According to the invention, the high-voltage bushing is no longer placed in a boiler filled with oil, but is part of a mobile device connected to a winding in said boiler by means of a cable.

A swirler for creating a swirling fuel/air mix is presented. The swirler has vanes extending radially around a central axis of the swirler and positioned on an annular base. The swirler has mixing channels for mixing the fuel and the air. At least one mixing channel is defined by opposing walls of two adjacent vanes. At least one of the opposing walls includes a primary side injection opening for ejecting a stream of fuel into the mixing channel; and a secondary side injection opening which corresponds to the primary side injection opening and is for ejecting a jet of fuel into the mixing channel. The secondary side injection opening is positioned on the wall such that the jet from the secondary side injection opening creates turbulence, within the mixing channel, in the stream from the primary side injection opening. The turbulence increases mixing of fuel and air.
