摘要:
A wave energy transformation device comprising an array of members connected together to form a structure having a substantially hexagonal geometry, the array has link members, nodes and absorbers and the relative motion of at least some of the members of the array, as caused by the energy of wave motion in a medium to which the array is coupled is convertible to another form of energy. The device is suitable for generating electrical energy from sea waves.

A method of brazing a honeycomb for air sealing onto a braze surface of the front end of the stationary blade of an axial-flow compressor in accordance with the invention includes the steps of: placing a filler sheet between the honeycomb and the braze surface; constraining the honeycomb in the seal width direction so that the seal width direction of the honeycomb corresponds to the seal width direction of the braze surface whilst keeping the configuration of the honeycomb at the same curvature as that of the braze surface; and heating the assembly to braze the honeycomb and the braze surface.

Die vorliegende Erfindung betrifft Diffusorbauteil für eine Gasturbine, wobei über das Diffusorbauteil (6) eine Fluidströmung in Richtung einer Brennkammer (10) der Gasturbine verlangsamt werden kann und sich hierfür ein Strömungsquerschnitt des Diffusorbauteils (6), der durch eine Diffusorwandung (11) definiert ist, erweitert. Erfindungsgemäß ist die Diffusorwandung zumindest lokal versteift, indem an der Diffusorwandung (11) mindestens ein Versteifungselement (13, 13a, 13b) mit einer gitterförmigen Struktur vorgesehen ist. Ein zugehöriges Gasturbinentriebwerk mit einem solchen Diffusorbauteil wird ebenfalls präsentiert.

Wind turbine blades comprising one or more deformable trailing edge sections having a multistable sheet comprising a plurality of bistable elements, each bistable element having two stable positions, wherein the multistable sheet is attached in a cantilever manner to a structural portion of the blade and extends in a chordwise direction, and the multistable sheet is connected to a skin of the blade such that upon changing one or more bistable elements from one stable position to the other stable position a shape of the trailing edge section changes. The application further relates to wind turbines comprising such blades and methods of controlling loads on the blades.

L'objet de l'invention est un procédé de réalisation d'un panneau pour le traitement acoustique, caractérisé en ce qu'il comprend les étapes consistant à : - assembler deux plaques dont au moins une est déformée de manière à écarter les plaques de façon localisée afin de former entre les deux plaques des cavités d'une structure alvéolaire, lesdites cavités étant délimitées par des facettes (48) et des cloisons formées par au moins une des plaques déformées, - réaliser au moins un orifice (62) sur les facettes (48) d'une des deux plaques, et - à plaquer une couche acoustiquement résistive (64) contre la face de la structure alvéolaire comportant les orifices (62).
摘要:
The invention relates to a concrete construction of modular design, comprising at least two upright precast concrete wall elements (7, 7',..., 7''') which are arranged next to one another and, where appropriate, above one another and have two narrow sides, an upper and a lower side and a front and a rear side, wherein a first honeycomb support (1) is anchored in one of the narrow sides and the opposite narrow side has a recess or depression (8) in which a further honeycomb support (1') is anchored in such a way that, when mounting the narrow sides of the two precast concrete wall elements (7, 7'), the two honeycomb supports (1, 1') can be connected by connecting means (9) with the formation of the vertical joint (16).
