Abstract

Ujawniono układy i sposoby regulacji kąta skoku śmigła i zespół wirnikowy, który selektywnie ogranicza kąt skoku w zależności od wybranego trybu pracy. Układ zawiera siłownik (45) mający przednią i tylną komorę, łożysko olejowe (OTB) oraz kołnierz z precyzyjnym zatrzymaniem. Kołnierz z precyzyjnym zatrzymaniem zawiera pierwszy kanał przepływowy w połączeniu płynu z OTB oraz z komorą przednią w trybie pracy naziemnej, oraz drugi kanał przepływowy w połączeniu płynu z OTB oraz z komorą przednią w trybie pracy podczas lotu.
