Definitions
- Lightning protection system for the union of a blade composed of two modular parts joined together, the root zone or inboard and the tip zone or outboard and the method of forming the stack that houses the metallic elements of the joint of the blade. shovel.
- the stacking that houses the metal elements of the joint is very thick. As constructively it is very difficult to infuse such great thicknesses, it is resorted to the incorporation of fiberglass sheets or fabrics sandwiched between the carbon fiber sheets or fabrics.
- the laminate thus formed distributes the resin during infusion and allows the use of great thicknesses. What happens is that, by adding fiberglass, an insulating effect is produced. This potential difference can lead to an electric arc jump that must be avoided.
- the first group includes the following:
- Patent application EP1826402A1 uses a plate integrated in carbon fiber as a branch of the main lightning cable. This plate is placed during the lamination and curing process. A nanocomposite based on a conductive resin, laminated in the construction process of the blade beam, is also described.
- Patent application EP1692752A1 connects the carbon fiber with the lightning cable through a potential equalization member that is an electrical conductor.
- Said electrical conductor is a flexible metallic tape or a flexible mesh that is added to the carbon fiber to improve its conductivity, (since the conductivity is not very good in the longitudinal direction of the fibers).
- Patent application EP1664528A1 presents a protection method with a fiber-reinforced main laminate connected to a receiver and a lightning cable.
- the fibers can be carbon fiber, steel fibers, etc.
- a stack of fiberglass and carbon fiber in a 7 to 1 ratio is described in which, to compensate for the lack of conductive fiberglass, a glued receiver (with silver glue that is conductive) is added to a laminate of steel fibers that is added to obtain the equipotential difference of the whole.
- the lightning strikes the receiver located at the tip of the blade and travels through the internal cable to the root of the blade, to finally travel to the ground.
- the blade has a discontinuity in its structure, all the elements that make up the discontinuity must be teamed and joined to the cable that transfers the lightning strike.
- Patent application EP1561947A1 places a metal plate between the two parts of the modular blade and an electrical conduction wire internal to the blade. When lightning strikes, it is possible to guide the current to the outside of the blade through the metal plate and the electrical conduction wire. The union is completed with a nut, a bolt and its corresponding plate.
- Patent application EP1950414A1 presents a modular blade made of fiber-reinforced plastic materials (FRP).
- FRP fiber-reinforced plastic materials
- the non-conductive parts are joined by means of fixing elements made up of fasteners arranged on the inside of the blade and a lightning discharge conductive cable is added to all of this.
- the fixing elements are arranged inside their corresponding holes and are covered with a non-conductive cover but which is crossed by some protruding fasteners. An extension of the lightning conductor cable is connected to each of the clips.
- Patent application EP2282057A1 presents a mesh for equipotentiating and reinforcing fiber blades, whose cables are grouped at conical ends to achieve a connection point.
- the different reorganizations of the cables present different practical realizations:
- the transversal cables are intertwined forming the conical end (which connects their free ends).
- Longitudinal wires create the join, but with multiple tapered ends.
- an L-shaped contact strip is used, which creates the physical connection.
- Patent application WO2020094633A1 describes an internal carbon fiber beam to which a conductive element is added to equip the assembly.
- Said conductive element extends along the outside of the stringer structure or along a corner of the outside of the stringer structure.
- the beam can be made up of a double beam or a single beam. It also contemplates the modularity of the blade by assembling the aforementioned beams.
- the carbon fiber and fiberglass laminates that form part of the joining area of the modular blade, as well as the metallic elements that make up the joint are equi-potential when connected to the drop cable and in this way the lightning impact does not damage them.
- the laminates corresponding to fiberglass and which are not conductive are replaced with a copper mesh or an aluminum mesh, both being conductive materials.
- the carbon fiber laminates, which are conductors and are intermingled with the fiberglass ones, from a certain point are only intermingled with several copper meshes, equipping the whole set.
- the stack of sheets of the invention comprises several folds of carbon fiber interspersed with several copper meshes and covered by a fiberglass that covers the entire assembly. It also includes inside a metal band for:
- the lightning protection system is located on the wing of the blade and covers the same width as the preform that forms the joint.
- the equipotential stacking is infused at the same time that the cap is formed. It is not a dressing that is added to the side of the cap after its manufacture.
- the stack formed has such a thickness that it favors the handling of the copper mesh during its manufacture, folding it and inserting the metal band inside it quickly and comfortably. Covering the entire exterior of the stack with fiberglass favors the subsequent infusion process, providing the whole with adequate protection.
- Figure 1 represents the outline of a modular blade with the two joining preforms overlapping inside it.

- the metallic elements that make up the union of this modular blade are arranged in the upper cap (4) and in the lower cap (5).
- Said caps (4 and 5) and their corresponding webs, together with the joining area (1), constitute two preforms, one upper and one lower, which overlap on the original beam structure of the blade. So, as they move away from the junction point (1), the cap narrows and thins its thickness so that the overlap with the rest of the interior of the blade is more effective.
- the material used in the cap is fiberglass and carbon fiber in a ratio of 20% to 80%.
- Figure 2a shows the joining area (1) of the lower cap (5) with its tip side (2) and its root side (3).
- Said metallic joint rests on the lower shell of the blade and due to its aerodynamic configuration, the preform of the joint is closer to the leading edge (7) or leading edge and further from the trailing edge (8) or trailing edge.
- the stack (9) is arranged, equipping the composite material that houses the metal elements of the joint.
- the lightning protection system of the lower cap (5) shown in figures 2a and 2b has two stacks (9) on the leading edge (7) and another two stacks (9) on the trailing edge. output (8).
- the sides of the lower cap (5) house some centering pins (10) that help to complete the in-situ assembly of the modular blade and that are subsequently removed.

- the stack (9) is approximately 150mm or 250mm long and 50mm or 80mm wide. Measured from the joint area (1) and more specifically from the last metallic element that makes up the joint.
- Figure 3 shows a section of the modular blade object of the invention. It includes the tip area (2), the root area (3), the leading edge (7), the trailing edge (8) and the joint area (1) covered by the metallic elements that constitute the joint itself.
- the set of Xpacers â that cover and prestress the union bolts, which in turn are threaded in their corresponding inserts, which are glued to the laminated combination of carbon fiber and fiberglass that must be equipped.
- the Xpacers are the metal elements visible when the joint is complete.
- the shells that cover the upper have holes (11) in the joint area (1) to allow access during assembly. Subsequently, these holes (11) will be covered with a hull.
- the stacks (9) equipped with the trailing edge (8) comprise a metal band (12) that protrudes from its interior.
- Said band (12) has a hole for its connection with other elements.
- the stack (9) of the tip (2) and the stack (9) of the root (3) corresponding to the lower cap (5) are joined together with another metal band (13) screwed through the corresponding connection holes of the metal band (12) mentioned above.
- This union is complemented by the metal band (14) that covers all of the Xpacers (15).
- Said metal band (14) is screwed to each and every one of the Xpacers (15) contained in the joining area (1).
- the union (16) that joins the metallic bands (12) of the stacks (9) corresponding to the tip zone (2) and the root zone (3) together with the metallic band (14) of the Xpacer (15) also serves as a link with the lightning down cable (17), where the entire assembly is equipped.
