An apparatus for wind energy conversion includes a nacelle having a main frame, the main frame having a lower part and an upper part joined to the lower part, the upper part having a first strap extending across the lower part; a stator disposed within the nacelle; a rotor disposed within the nacelle; a mounting surface attached to the main frame and defining a rotor space, the mounting surface having a first side-face that exposes the rotor space; and a flange rotatably supported on the main frame and including a first end connected to the rotor. The rotor is cantilevered from the flange into the rotor space from the first side face.

Some general aspects of the invention provide a foundation fixing unit (202, 204, 400) for fixing a tower (108) of a wind energy converter (100) onto a foundation (110). The unit comprises a fixation plate (202) fixable to the foundation (110), walls forming at least one tower fixation hole (300) in the intermediate plate (202) for passing a tower fixation bolt (220) through the fixation plate (202) in order to fix the tower (108) to the fixation plate (202), a tower fixation nut (400) arranged below the at least one tower fixation hole (300) for receiving a threaded portion of the tower fixation bolt (220) and a nut cage (204) holding the tower fixation nut (400), the nut cage (204) being attached to a bottom surface (222) of the fixation plate (202). Under further aspects, the invention provides a wind energy converter tower comprising the foundation fixing unit (202, 204, 400) and a method for fixing a wind energy converter tower onto a foundation.

A method for adjusting a pivotally mounted rotor blade of a wind energy converter includes controlling a first drive and a second drive to collectively turn the rotor blade into an operating position; detecting whether a failure of the first drive has occurred; activating, when the failure of the first drive has occurred, a first activatable lockout connected to the rotor blade, which prevents turning of the rotor blade into the operating position while allowing turning of the rotor blade into a feathered position; and controlling, when the failure of the first drive has occurred, the second drive to turn the rotor blade into the feathered position.

The invention relates to a silencer (1) for noise-laden gas pipes, especially for a suction pipe and/or an exhaust pipe of an internal combustion engine, comprising an outer pipe (2) with an inlet side (3) and an outlet side (4), a plurality of diaphragm rings (9, 9′, 9″, ′″, 9″″) each with an outer surface connected (5) to the inner surface of the outer pipe (2), at least one insert (6) with an outer surface connected (7) to the inner surface of the outer pipe (2) and/or the diaphragm rings (9, 9′, 9″, 9′″, 9″″) and with a plurality of openings (8) which are closed on one side. Said insert (6) forms sub-pipes for the gas flow in the silencer, and the openings (8), which are closed on one side, open into the sub-pipes, the depth thereof being /4 in relation to the wavelength of a frequency to be silenced. At least one perforated wall (10, 10′, 11, 11′), extends between at least two diaphragm rings (9, 9′, 9″, 9′″, 9″″) whereby an outer surface is connected (7) to at least one inner surface of the two diaphragm rings (9, 9′, 9′″, 9″″, wherein at least one resonance cell is fixed between the two diaphragm rings (9, 9′, 9″, 9′″, 9″″) of the perforated wall (10, 10′, 11, 11′) and the outer pipe (2).
摘要:
A fluid guideline with at least two structural elements made of substantially soundproof material has at least one opening for sound damping. An impedance change (in particular in the form of an impedance discontinuity) of the flow resistance of the fluid flowing through the fluid guideline is present between two adjacent structural elements, and the at least one opening is arranged in the region of the impedance change between two adjacent structural elements.

An apparatus for sonic coupling between an intake tract or engine compartment and a vehicle interior of a motor vehicle has a housing into which sound enters from the intake tract via a first line, and out of which sound exits into the vehicle interior via a second line. A transmission body is arranged in the housing, the transmission body having a gas-tight separating wall between a sound inlet into the housing and a sound outlet out of the housing. The position of the separating wall is held essentially constant by a positioning device. A transmission wall between the separating wall and the housing provides an acoutis transfer function that is adjustable. The separating wall runs generally perpendicular to the longitudinal axis of sound propagation and the transmission wall runs at an angle α to the longitudinal axis of sound propagation.

A reed valve includes a generally wedge shaped reed cage or block defining a fluid flow passage and having substantially coplanar discharge ports. A reed is mounted at a common hinge end to the reed cage and has a plurality of petals each of which overlies a corresponding one of the ports. The petals have predetermined edge profiles to establish different transverse widths at their hinge axes so that the petals overlying outer low pressure zones in the reed cage lift from their port closing positions at a lower fluid pressure than the petals that overlie higher pressure zones in the reed cage, thereby providing multiple stage lifting and reflex action by the reed petals relative to the reed cage ports.
