Abstract

Łopata wirnika nośnego o zmiennym kącie skręcenia, posiadająca dźwigar, wypełnienie łopaty, elementy z materiału z pamięcią kształtu charakteryzuje się tym, że wewnątrz łopaty znajduje się dźwigar składający się z belki poziomej (2b) oraz połączonej z nią w jej środkowej części, co najmniej jednej belki pionowej (2a). Z górnym końcem belki pionowej (2a) połączona jest połączeniem odkształcalno-uchylnym środkowa część górnej poprzeczki (2c), natomiast z dolnym końcem belki pionowej (2a) połączona jest połączeniem odkształcalno-uchylnym w środkowej części dolna poprzeczka (2d). Pomiędzy skrajnymi końcami belki poziomej (2b) a górną poprzeczką (2c) i pomiędzy skrajnymi końcami belki poziomej (2b) oraz dolną poprzeczką (2d) znajdują się elementy z materiału z pamięcią kształtu (1a, 1b, 1c, 1d).A main rotor blade with a variable angle of twist, having a spar, blade filling, elements made of shape memory material, is characterized by a spar inside the blade consisting of a horizontal beam (2b) and at least one connected to it in its central part vertical beam (2a). The middle part of the upper crossbar (2c) is connected to the upper end of the vertical beam (2a), while the lower crossbar (2d) is connected to the lower end of the vertical beam (2a) by a deformable-tilt connection in the middle part. Between the extreme ends of the horizontal beam (2b) and the upper crossbar (2c) and between the extreme ends of the horizontal beam (2b) and the lower crossbar (2d) there are elements of shape memory material (1a, 1b, 1c, 1d).
