Abstract
Wirnik turbiny przepływowej działający w oparciu o profile aerodynamiczne, wyposażone w wyraźnie zdeterminowaną budową krawędź natarcia i krawędź spływu, przystosowany do pracy nominalnej przy szybkobieżności względem wiatru wyższej niż 1,5, charakteryzuje się tym, że rozpiętość kąta α, mierzona jako przesunięcie w osi obrotu łopat (1) między położeniem kątowym krawędzi spływu łopat, od 1/4 do 1/2 wysokości wirnika jest co najmniej 20 procent mniejsza, niż rozpiętość kąta β, mierzona jako przesunięcie w osi obrotu łopat (1) między położeniem kątowym krawędzi spływu łopat, od 1/2 do 3/4 wysokości wirnika.
