x = rcos(φ);
y = rsin(φ);
где ось z направлена вдоль оси ветроротора;
r - радиус - расстояние от точки до оси ротора;
φ - полярный угол в поперечном сечении ветроротора;
S - шаг винта;
f(r) - монотонная функция радиуса.1. Screw rotor containing a shaft and screw blades fixed to it, characterized in that the screw blades are funnel-shaped with Cartesian coordinates of surface points
x = rcos (φ);
y = rsin (φ);
where the z axis is directed along the axis of the wind rotor;
r is the radius is the distance from the point to the axis of the rotor;
φ is the polar angle in the cross section of the wind rotor;
S is the pitch of the screw;
f (r) is the monotonic function of the radius.
f(r) = (r-r1)ctg(γ); γ = arcsin((r2-r1)/h),
где r1 и r2 - внутренний и наружный радиусы ветроротора;
γ - угол между осью и образующей косого геликоида;
h - высота винтовой лопасти, рассчитываемая по формуле
при этом лопасть может быть выполнена из плоского кольца с внутренним радиусом
и наружным радиусом r2c = r1c + h.2. The screw rotor according to claim 1, characterized in that the funnel-shaped helical blades are made in the form of an oblique helicoid and are described by the formulas
f (r) = (rr 1 ) ctg (γ); γ = arcsin ((r 2 -r 1 ) / h),
where r 1 and r 2 are the inner and outer radii of the wind rotor;
γ is the angle between the axis and the generatrix of the oblique helicoid;
h is the height of the helical blade, calculated by the formula
while the blade can be made of a flat ring with an inner radius
and outer radius r 2c = r 1c + h.
