摘要： An for a Wind Energy Converting System (WECS in the following) for producing electric power, comprising the said de-icing and anti-icing arrangement and a method for preventing and eliminating the ice accretion on the blades of the rotor of an WECS are the subject matter of the present invention. Such an WECS (l; l'; 1'; 1'') is of the type comprising: - a tower (4; 4'), apt to support and anchor the said WECS (1; l'; 1'; 1'') to the ground or a basement, - a [nacelle](3), located on said tower (4; 4'), to which there are associated first means (9, 1N, 10; TR) for transforming the rotating movement of a rotor in order to generate electric power to be introduced into an electric [electric grid] and for the management and the operation of possible electric of said WECS (1), - a rotor (2), associated to said [nacelle](3) in the manner that it can be rotate with respect to said [nacelle](3), said rotor (2) comprising a number of blades (5) and susceptible of rotating because of the wind (V) which hits said blades (5), wherein said WECS (1; l'; 1'; 1'') internally comprises second means (2E, 19, 21) for the 15 flow of a fluid (F; F; F'; F'') inside volumes (14, 15) defined in the interior of said blades (5) of said rotor (2). The present invention is characterized in that the blades (5) of the rotor comprise, on at least a part of an external surface (5S), openings (12) which are in connection with the fluid of said volumes (14, 15) inside said blades (5) and are apt to realize an ejection of at least a part of said fluid (F; F; F'; F'') outside said blades (5), in order to fluid-thermodynamically interact with said wind (V) hitting at least said part of the surface (5S) concerned by said openings (12), and/or with water and ice possibly present on said external surface (5S) of said blade (5).

摘要： The invention relates to a porous element for the effusive cooling of components of engines working with a fluid at a high temperature, consisting of a substantially laminar structure obtained in an electrolytic bath by means of a galvanic electroforming process with deposition of a metal or metal alloy on a matrix arranged at the cathode and having conductive areas separated by insulating areas. Said laminar structure has an external surface that is smooth and devoid of roughness and being crossed by micro-holes that correspond to exposed insulating areas of said matrix and have diameters smaller than 300 microns, density of said micro-holes is from 2 to 10 dots/mm.
