6. Vindmøllevinge ifølge krav 1, hvor en agterportion af vingen er udformet af cellulært materiale 40, og hvor det cellulære materiale har et forkammer 42 defineret deri eller er forbundet med et forkammer, hvorigennem vingens transpiration kan styres aktivt ved blæsning eller sugning 44, 46 med henblik på at forbedre vingens aerodynamiske og aeroakustiske ydeevne.
7. Vindmøllevinge ifølge krav 1, hvor en agterdel af vingen er udformet af cellulært materiale, og hvor agterdelen, der er udformet af cellulært materiale, omfatter en flerhed af cellulære materialer 34, 36, 38 i en korderetning, hvor hvert af flerheden af cellulære materialer har mindst en egenskab, som er forskelligt fra et hosliggende coiiuiæri materiale.
8. Vindmøllevinge ifølge krav 1, hvor spidsregionen omfatter en spids 62, og hvor en del 66 af bagkanten 64 af vingen og spidsen 62 begge er lavet af cellulært materiale.
9. Vindmøllevinge ifølge krav 1, hvor spidsen omfatter en finnestruktur 58, og hvor finnestrukturen er udformet af et cellulært materiale 56, som har materialeegenskaber, som er forskellige fra et cellulært materiale 54, der er tilvejebragt i en hosliggende spidsregion af vingen.
10. Vindmøllevinge ifølge krav 1, hvor mindst en del af spidsregionen er lavet af metallisk skum 68, og hvor der i vingen er inkorporeret et lynbeskyttelsessystem 70, som er operativt koblet til den metalliske skumdel.
