Abstract

Regulowana łopata wirnika nośnego o zmiennym kącie skręcenia posiadająca dźwigar oraz wypełniacz charakteryzuje się tym, że do dźwigara zamocowana jest w kierunku krawędzi spływu co najmniej jedna belka (3) wykonana z materiału sprężystego odkształcająca się pomiędzy krawędzią górną (2) i krawędzią dolną (5). Do końcowej części belki (3) zamocowana jest pierwszym końcem linka (7a), która przechodząc poprzez system bloczków (8a) zamocowana jest drugim końcem do elementu z materiału z pamięcią kształtu zamocowanego na stałe do dźwigara.The adjustable rotor blade with a variable angle of twist having a spar and a filler is characterized by the fact that at least one beam (3) made of elastic material is attached to the spar towards the trailing edge, deforming between the upper edge (2) and the lower edge (5) . A cable (7a) is attached to the end of the beam (3) with its first end, which, while passing through the system of blocks (8a), is attached with its other end to a shape-memory element permanently attached to the spar.
