WO2023 / 007038A1
Transition of variable thicknesses of composite material lamitanes of a modular blade
Disclosed is a transition of variable thicknesses of composite material laminates of a modular blade when the thickness varies by 50-400% and which smooths the centroid distribution, the centroid being represented as a function of the thickness and material of the laminate with respect to the corresponding radius of the blade.
WO2023 / 012385A1
Transition for composite laminates for a modular blade
The present invention relates to a transition for composite laminates for a modular blade, said transition being characterised in that the real load distribution per element F2 is flattened, overlapping with the theoretical load distribution per element F2theor by means of a non-homogenous hybrid laminate across the width of same, with an area at the ends having a very high modulus of elasticity E2’ext and an area in the centre having a lower modulus of elasticity E2’int.
WO2024156924A1
Wind turbine self-lifting system and method of assembly
The invention relates to a self-lifting system formed by three masts with their corresponding winches, pulleys and cables, a lifting triangle that moves up and down between said masts and supporting bases, wherein the three masts are braced against each other. The system has a temporary foundation for supporting the tower sections (9, 9′, 9″) and the tripod or transition part during the assembly process. The lower flange of the sections incorporates a connection ring, where the complementary elements formed by struts and horizontal beams extending from the vertices of the triangle are assembled and joined to each other by a crossbar. The struts and the horizontal beams move in a retractable manner and fold by means of associated systems in order to release the tower segments. The method of assembly used lifts different types of tubular and mixed wind turbines with lower latticework.
WO2023 / 194631A1
Method for rearing the root of a blade
The present invention relates to a method for repairing the root of a blade having the following sequence: loosening the bolts of the root of the blade by removing the nuts in the bearing of the bushing . Lowering the blade to the ground using the Bladerunner® system.

WO2023 / 214097A1
Aligment and insertion system for lowering blades without using a crane
The invention relates to a system for lowering blades without using a crane, which solves the alignment and insertion problem resulting from the tilt and coning of the blade along the first/last 200-400 mm and the problem of space inside the hub.
WO2024062139A1
Lightning-protection device in a modular blade
A lightning protection device for the metal joint of a modular blade composed of two parts: the tip area or outboard module, where the lightning strikes and is conducted to the blade joint, and the root area or inboard module through which The beam is conducted from the joint to the hub of the wind turbine.
Wo2024028521A1
Method for obtaining an improved segmented blade
The invention relates to a method for obtaining an improved segmented blade, wherein, for a blade 95 m long with the joint disposes 25-30 m from the blade tip. The cord and overall itchiness in the 20 m of the outboard module are reduced by 75% the outboard module is extended by 1 m joining elements per cap are reduced form 10 to 8, and the blade mass form 800 kg to 640 kg, reducing the impact of the joint mass on the rest of the wind turbine; and loads at the blade root are reduced by 11% without affecting wind turbine productivity.
WO2024133978A1
Guiding systems for exchanging a wind turbine blade an use method
The invention relates to a guiding system for exchanging a wind turbine blade, which uses an internal lifting and lowering system fixed to a rotor. The guiding system is characterised in that it comprises semi-rigid passive retaining lines that form a safe catenary or track for lowering the blades without same hitting the tower or the ground as a result of incident winds of up to 15 m/s.

WO2023281127A1
Method for lifting and lowering blades without using a crane, and devices used
Disclosed is a method for lifting and lowering blades without using a crane, which uses an aligning and inserting device to solve the problem caused by the tilt and coning of the first/last 200-400 mm of the blade. The device comprises at least one hoist and a pair of cables coordinated by a pulley and screwed to a bearing by means of connecting elements at the ends thereof.
WO2024200881 A1
New transition piece for a wind turbine
The invention relates to a new transition piece for a wind turbine, formed by a hollow cylindrical monotubular segment with multiple connected rings, the upper part of the transition piece being the tower ferrule, the upper third comprising platforms and ribs, and the bottom part being a radial platform with brackets.
