Abstract: Provided is a wind turbine blade, with a generally hollow blade body including half shells and webs the webs including flanges connecting the respective web to the respective half shell, and with webs being supported via reinforcement structures relative to the respective half shell, which reinforcement structures are arranged between an outer and an inner layer of each half shell and extend in the lengthwise direction of the blade, whereby the reinforcement structures each include at least one stack composed of several glass fiber layers infused with resin, and that at least one stiffening element extending parallel to the first and second reinforcement structures over at least a part of their length including at least one stack composed of several pultruded composite strips including carbon fibers with the strips being fixed in the resin is arranged between the first and second reinforcement structures.

Abstract: A rotor blade of a wind turbine include sa first rotor blade segment having a first shell portion, a second rotor blade segment having a second shell portion and a joint connecting the first rotor blade segment with the second rotor blade segment between the first shell portion and the second shell portion, whereby the rotor blade further includes a fairing, the fairing covering the joint and being attached to the first shell portion and the second shell portion by means of an adhesive. Further provided is a wind turbine having this rotor blade.

Abstract: Provided is a wind turbine blade, with a generally hollow blade body including half shells and webs, with each web including flanges with the first and second webs being supported via respective reinforcement structures relative to the respective half shell, which reinforcement structures are arranged between an outer and an inner layer of the upper and lower half shell of the shells and extend in the lengthwise direction of the blade, wherein the first and second reinforcement structures each include at least one stack composed of several pultruded composite strips including carbon fibers with the strips being fixed in the resin, wherein at least one stiffening element extending parallel to the reinforcement structures over at least a part of their length comprising at least one stack composed of several glass fiber layers infused with resin is arranged between the reinforcement structures.

Abstract: Provided is a turbine blade, with a first and a second elongated web connected to an upper and a lower half shell, with each web including an upper and a lower flange connecting the respective web to the respective half shell, and with the first and second webs being supported by respective first and second reinforcement structures, which reinforcement structures extend in the lengthwise direction of the blade, wherein each first and second reinforcement structure supporting the first and second web includes at least one stack composed of several pultruded composite strips including carbon fibers with the strips being fixed in a resin matrix, wherein each at least one stack composed of the pultruded composite strips is an integral part of the respective first and second web and builds the respective flange, which is attached to the inner layer of the respective upper and lower shell.

Abstract: Provided is a turbine blade, including shells and webs connected to the shells, with, with each web being supported by reinforcement structures, whereby a first reinforcement structures includes at least one stack composed of several pultruded composite strips including carbon fibers with the strips being fixed in a resin matrix, and a second reinforcement structures supporting a second web either include at least one stack composed of glass and/or carbon fiber layers infused with resin, the stack being disposed between an outer and an inner layer of upper and lower shell, or at least one stack composed of glass and/or carbon fiber layers infused with resin or of several pultruded composite strips including carbon fibers with the strips being fixed in a resin matrix, which stack is an integral part of the second web and builds the flange.

Abstract: Opening and secure-closing system for doors comprising two doors (1,2) for accessing the interior of a chamber, which open towards the outside being hinged around two hinging axes (19,20), both doors (1,2) comprising a set of bolts (17,18) and the opening and closing system comprising additional means of opening/closing operation (26) and an overpressure door (3) located in one of the doors (1,2) which opens towards the outside, in such a way that the means of opening/closing operation (26) comprise a blocking bar (4), a blocking fitting (7) and means of retention (10) between the two doors (1,2) in order to provide a controlled and sequential opening/closing operation of the chamber, and the overpressure door (3) is opened automatically in the event of emergency due to overpressure, and it also participates in the controlled and sequential opening/closing operation of the chamber.

Abstract: Support system suitable for sustaining an auxiliary power unit of an aircraft to a fixed structure (2) belonging to a compartment of the auxiliary power unit (6) of the aircraft. The support system is made in a high mechanical strength material and with high resistance to ignition, and comprises three fittings (3, 4, 5) two of which are frusto-conical and one with a substantially cylindrical. Fittings (3, 4, 5) being able to be hollow and being able to comprise an array of lateral ribs. Each one of them presenting a first end (7) comprising means of attachment of the support system (8) to the fixed structure (2) and a second end (9) comprising means of securing of the support system (8) which are joined to the auxiliary power unit (1) in the periphery of the extension of said auxiliary power unit (1).
