Abstract: A pendulum mass damper is directed to damping oscillation of tall buildings, towers or similar flexible structures requiring a low frequency tuned mass damper (TMD) for reducing a e.g. wind or earthquake induced displacement response of the structure. A mass (1) is balanced by a first spring system (2a, 2b, 2c) and supported by a carrying part (4) to maintain a vertical position, the carrying part (4) carrying the mass in the vertical direction extends between the mass and a position (C) below the mass, i.e. the weight of the mass is carried or supported from or at a point or level below the mass, wherein the mass at the position (C) below the mass is fixed and/or connected to a unit (5) constituting a base of a supporting system for the mass which unit is floating i.e. the unit can move either horizontally or both horizontally and vertically.

Abstract: A damper for damping movements of a wind turbine, in particular for damping oscillatory movements of a tower of the wind turbine is provided. The damping of the movements is achieved by an aqueous liquid contained in a container of the damper. The aqueous liquid includes water and the components included in the aqueous liquid are completely dissolved. The composition includes a citrate, e. g. potassium citrate and/or sodium citrate. A wind turbine including the damper is also provided. Finally, a specific composition is provided. The composition is destined to be dissolved, e. g. in water, to result in the aqueous liquid.

Abstract: A damper position-limiting device is provided, which is mounted in a tower to limit the swing amplitude of a damper installed in the tower. The damper position-limiting device includes at least one web and a position-limiting ring. The web is provided with a mounting hole and at least one stress relief hole. A first side wall of the web has a first specified length along a circumferential direction of the inner wall of the tower, and is connected to the inner wall of the tower. The position-limiting ring is positioned within the mounting hole and connected to the mounting hole and is configured to accommodate an impacting plate of the damper.

Abstract: A floating wind turbine assembly, configured to self-stabilize in water without a fixed anchor. The floating wind turbine assembly has a wind turbine, joined to a turbine shaft. A beam anchor is joined to the turbine shaft. A hollow moving mass, arranged around the beam anchor, such that the hollow moving mass can be moved up or down the beam anchor. The hollow moving mass includes a pump, having a pump first end connected to the water with a first pump hose and a pump second end arranged within the hollow moving mass with a second pump hose.

Abstract: The invention relates to a device of a safety system and/or resource and energy-efficiency improvement system for influencing the flow around an aero- or hydrodynamic body, preferably an aerofoil, according to the principle of a back-flow flap, characterized in that: said device, together with the aero- or hydrodynamic body, in particular aerofoil, form at least a partial shift of the delimitation of the flap region by means of the back-flow flap and the delimiting component thereof when the back-flow flap is partially and/or completely raised, thus influencing the trailing edge separation vortex/vortices and/or the flap separation vortex/vortices; and in that the delimitation of the flap region shifts completely up to or beyond the profile trailing edge, or shifts only to a section in front of the profile trailing edge. The delimitation component is movably connected to the aerofoil by means of a basic element and is preferably permanently secured and/or releasably secured for maintenance purposes, thus ensuring a long service life for the rotor blade and/or wind turbine and/or flap system, preferably >5 years, particularly preferably >10 years, and most particularly preferably >=20 years, and/or thus optionally allowing simple removal/replacement.
