Title
(EN) IMPROVEMENTS TO A HELICAL FAN/PUMP/TURBINE
(FR) PERFECTIONNEMENTS APPORTÉS À UN VENTILATEUR/POMPE/TURBINE HÉLICOÏDAL(E)
Abstract
(EN)
Fan, turbine or pump with a substantially helically shaped blade, wherein the fluid intake is axially aligned to a longitudinal axis. The blade within the fluid intake portion has a flat and/or concave pressure face, and a root that is helically shaped to the longitudinal axis according to a logarithmic, exponential, power or other sequencing such that the tangent to the blade approaches perpendicular alignment to the axis at a first end of fluid intake portion and approaches parallel alignment to the axis at a second end of fluid intake portion. The fluid outlet is longitudinally offset from the fluid intake. Alternatively, a second substantially helically shaped portion has an opposite chirality to the first substantially helically shaped portion.
(FR)
L'invention concerne un ventilateur, un turbine ou une pompe dotée d'une pale sensiblement en forme d'hélice, l'admission de fluide étant alignée axialement par rapport à un axe longitudinal. La lame située à l'intérieur de la partie d'admission de fluide a une face de pression plate et/ou concave, et une racine qui est mise en forme hélicoïdale par rapport à l'axe longitudinal selon un séquençage logarithmique, exponentiel, de puissance ou autre, de sorte que la tangente à la lame s'approche de l'alignement perpendiculaire à l'axe au niveau d'une première extrémité de la partie d'admission de fluide et s'approche de l'alignement parallèle à l'axe au niveau d'une seconde extrémité de la partie d'admission de fluide. La sortie de fluide est décalée longitudinalement par rapport à l'admission de fluide. En variante, une seconde partie sensiblement en forme d'hélice a une chiralité opposée à la première partie sensiblement en forme d'hélice.
