Abstract

Przedmiotem wynalazku jest rotor, charakteryzujący się tym, że łopaty rotora (4A) są ukształtowane w przekroju poprzecznym z krzywych tworzących spirale logarytmiczne o dwóch różnych wykładnikach, wychodzących z jednego punktu na pobocznicy rotora oraz zamykającego je od strony wewnętrznej okręgu o środku wyznaczonym przez oś obrotu rotora o promieniu zbliżonym do fi2 albo większym do niego, gdzie fi wynosi albo jest przybliżone do 0,618, a spirala od strony nawietrznej ma mniejszy promień niż krzywa spiralna od strony zawietrznej oraz spirala od strony nawietrznej rozpostarta jest na mniejszym kącie niż ta od strony zawietrznej, a łopaty wydłużone są pionowo w całym zakresie wysokości rotora, przy czym łopaty rotora (4A) umocowane są względem siebie w ten sposób, by przestrzeń w bezpośrednim sąsiedztwie osi rotora była pusta na całej swojej wysokości.The subject of the invention is a rotor, characterized in that the rotor blades (4A) are formed in cross-section from curves forming logarithmic spirals with two different exponents, coming from one point on the side of the rotor and closing them from the inside of the circle with the center determined by the axis of rotation a rotor with a radius close to or larger than fi2, where fi is or approximates to 0.618, and the windward spiral has a smaller radius than the spiral curve on the leeward side and the spiral on the windward side is spread over a smaller angle than that on the leeward side, and the blades are vertically elongated throughout the entire height range of the rotor, with the rotor blades (4A) fixed in relation to each other in such a way that the space in the immediate vicinity of the rotor axis is empty along its entire height.
