Abstract
Official abstract text for this publication.
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.
