Fairing for a modular blade

A fairing for a modular blade of a wind turbine generator, comprising a joining zone disposed between two consecutive modules of the modular blade wherein the fairing comprises:

• a rigid suction side fairing configured to be arranged on a suction side of the modular blade;
• a rigid pressure side fairing configured to be arranged on a pressure side of the modular blade, comprising a metal mesh configured to equipotentially bond the fairing with a lightning cable and a plurality of holes distributed at both ends of the rigid pressure side fairing to house fixing elements which are configured to allow attachment to a shell of the modular blade;
• a leading edge fairing cooperating with a first end of the rigid suction side fairing and with a first end of the rigid pressure side fairing;
• and
• a trailing edge fairing cooperating with a second end of the rigid suction side fairing and with a second end of the rigid pressure side fairing, wherein both the leading edge fairing and the trailing edge fairing comprise an element of elastomeric material and a rigid framework of glass fiber that supports the element of elastomeric material, each rigid framework comprises peripheral holes that comprise metal inserts or bushings that are passed through by fixing elements that are configured to allow the fairing to be joined to the shell of the modular blade and the metal inserts or bushings are configured to equipotentially bond the fairing with the lightning cable, and
• the width of the fairing is configured to cover a joining zone of the modular blade of between 0.5 and 1% of a length of the modular blade.
