Abstract: A connection member to connect a blade with an arm of a vertical axis wind turbine is disclosed. The connection member may include a bracket including a bracket plate. A bracket plate curvature may be equivalent to a blade inside portion skin curvature. The bracket plate may include a first connection insert configured to receive a first fastener. The bracket plate may be attached to the blade via the first fastener. The connection member may further include a yoke including a second connection insert configured to receive a second fastener. The yoke may attach to the arm via the second fastener. The connection member may further include a pivotal pin configured to axially attach the bracket with the yoke and a device to attach a fairing to the blade.

Abstract: The invention relates to a device basically consisting of the packaging of matrices of parallel tubes that act as pressurised containers. Both ends of each tube are hermetically connected to collectors located in the vicinity of the ends of the tubes. The collectors have multiple accommodations distributed according to the packing pattern of the tube matrix, there being an accommodation for each tube end. At least one collector has an internal channel that allows the connection of fluids between the tubes forming the tube matrix. This collector has an opening that allows fluid exchange between the inside of the tubes and the outside. The assembly comprising the tube matrix and collectors is surrounded by a structural belt. The collectors have a rounded geometry in the area of contact with the belt. Reinforcement fibres of the belt are mainly arranged parallel to the axis of the tubes. Reinforcement fibres of the tubes are mainly arranged in the circumferential direction of same.
