AN IMPROVED WIND TURBINE MULTI-PANEL BLADE

摘要

A wind turbine blade transversely divided in an inboard module (13) and an outboard module (33) provided on their end sections with connecting means, comprising, respectively, an inboard spar (15), an inboard upper shell (17) and an inboard lower shell (19); an outboard spar (35), an outboard upper shell (37) and an outboard lower shell (39); and arranged so that the aerodynamic profile of said inboard and outboard modules (13, 33) is defined by said upper and lower shells (17, 19; 37, 39), in which the inboard spar (15) is composed of two cap prefabricated panels (21, 23) and two web prefabricated panels (25, 27), and the outboard spar (35) is composed of first and second prefabricated panels (41, 43) integrating its caps (45, 47) and webs (49, 51). The invention also refers to a method of fabricating said wind turbine blade.
