Claims (14)

1. Vingearrangement (100) omfattende: et hovedrotorblad (22), hvilket hovedrotorblad (22) indbefatter en trykside (62) og en sugeside (64), der strækker sig mellem en forkant (66) og en bagkant (68); et ekstra rotorblad (110, 112) hørende til hovedrotorbladet (22), hvilket ekstra rotorblad indbefatter en trykside (122) og en sugeside (124), der strækker sig mellem en forkant (126) og en bagkant (128); og et støtteelement (150), der forbinder det ekstra rotorblad (110, 112) til hovedrotorbladet (22), hvor det ekstra rotorblad (110, 112) er konfigureret til at ændre en løftekraft (90) hørende til vingearrangementet (100), og kendetegnet ved, at det ekstra rotorblad (110, 112) er konfigureret til at blive passivt aktiveret, når vingearrangementet (100) udsættes for en belastning (92), der er større end eller omtrent lig med en belastningsgrænse (94), hvor belastningen (92) resulterer fra en tilsvarende løftekraft (90).
2. Vingearrangement (100) ifølge krav 1, hvor det ekstra rotorblad (110, 112) er forbundet med én af tryksiden (62), sugesiden (64), forkanten (66) eller bagkanten (68) af hovedrotorbladet (22).
3. Vingearrangement (100) ifølge et hvilket som helst af krav 1-2, hvor det ekstra rotorblad (110, 112) er en flerhed af ekstra rotorblade (110, 112).
