    摘要： Eine Heißgaskammer, insbesondere Brennkammer für ein Triebwerk zum Ausstoß einer heißen Gasströmung, insbesondere für ein Raketentriebwerk, mit einer Brennkammerwand (15), die eine inneren Oberfläche (12', 12") und an diese außen angrenzende Kühlkanäle (14) aufweist, zeichnet sich dadurch aus, dass die zur Brennkammer (4) weisende innere Oberfläche (12', 12") der Brennkammerwand (15) zumindest bereichsweise zur Vermeidung von Filmkondensation ausgestaltet ist.

    摘要： An article has an anodised titanium or titanium alloy surface layer containing pores which form recesses opening to the outside of the layer. A wetting-resistant coating is formed on the anodised surface layer. The coating penetrates the pores but retains the recesses to make the surface of the article hydrophobic and thereby restrict accumulation of ice.

    摘要： Different shapes of rotor blades for wind energy plants are known. In a wind energy plant the rotors and more particularly their blades are the main source of noise. To improve acceptance of wind energy and comply with noise reduction legislation the aim is to work towards keeping noise emissions as low as possible, especially since wind energy plants are often set up near residential areas. The noise at present emitted by wind energy plants or wind energy conversion systems also means that they meet with resistance from sectors of the population. As a result, such plants are sometimes difficult or even impossible to install since, owing to the applicable environmental protection standards and the fact that noise too is considered a form of environmental pollution, the authorities refuse permission for wind energy plants. The aim of the invention is therefore to further reduce the noise emissions of wind energy plants. To this end the invention provides for a rotor blade to have means for reducing a noise emitted by such a blade, said means being embodied by a liquid-repellent layer and/or surface which is configured on at least a partial surface of the rotor blade.
