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.The double-stream rotor is characterized in that it has two rows of blades (2) and (3) attached to the rotating hoop (1) in pairs - to the inside and outside of the rotating hoop (1) and separated from each other by the rotating hoop (1), wherein each blade has an opposite blade; wherein the blades (2) and (3) are attached to a stabilizing ring (9) which holds all blades (2) and (3) in relation to the ring at the same angle of attack; wherein the blades (2) and (3) are rigidly connected in pairs (one in relation to the other) and mounted in a shaft (5) so that they can rotate in relation to the axis of the shaft (5); wherein the inner blade (2) is integrated with the outer blade (3), and the resultant angle of attack of both blades is determined automatically (self-adjusting) as a result of the rotational movement as a result of mutually transferred forces resulting from the shape of the blades and the forces occurring in connection with their rotational movement; wherein the stabilizing ring (9) keeps all blades (2) and (3) at the same angle of attack.
