Abstract

uma lâmina de turbina de eólica é provida com duas partes do invólucro cada uma, pelo menos parcialmente, feita de uma estrutura em sanduíche, incluindo uma casca interior (76), uma casca exterior (74) e um material de núcleo intermediário (75, 77), em que as partes do invólucro são unidas pelo menos ao longo de seus respectivos bordos de ataque (18). a lâmina também compreende uma seção de espaçamento que se prolonga longitudinalmente, na qual os respectivos bordos de fuga (58a, 58b), da parte do invólucro do lado de pressão e da parte do invólucro do lado de sucção estão espaçados, em que uma alma do bordo de fuga (45) está disposta entre e conectada à estrutura em sanduíche, da parte do invólucro do lado de sucção (84, 86, 87), e a estrutura em sanduíche, da parte do invólucro do lado de pressão (74, 76, 77).
