Abstract

Wirnik dwustrumieniowy charakteryzuje się tym, że na obręczy obrotowej (1) posiada zamocowane dwa rzędy łopat (2) i (3) zamocowanych w parach - do wnętrza i na zewnątrz obręczy obrotowej (1) i odseparowanych od siebie obręczą obrotową (1), przy czym każda łopata posiada łopatę przeciwną; przy czym łopaty (2) i (3) przytwierdzone są do pierścienia stabilizującego (9), który utrzymuje wszystkie łopaty (2) i (3) względem pierścienia pod tym samym kątem natarcia; przy czym łopaty (2) i (3) połączone są w parach na sztywno (jedna względem drugiej) i osadzone w trzpieniu (5), tak że mogą obracać się względem osi trzpienia (5); przy czym łopata wewnętrzna (2) zintegrowana jest z łopatą zewnętrzną (3), a wypadkowy kąt natarcia obydwu łopat ustalany jest samoistnie (samonastawnie) w wyniku ruchu obrotowego jako wynikowa wzajemnie przenoszonych sił wynikających z kształtu łopat oraz sił występujących w związku z ich ruchem obrotowym; przy czym pierścień stabilizujący (9) utrzymuje wszystkie łopaty (2) i (3) pod tym samym kątem natarcia.
