The present invention relates to a combination of two vertical axis Savonius-type rotors (20,120) mounted on a support structure (210) and a deflector plate (200). The deflector plate serves an an augmentation apparatus which considerably increases the power output of both Savonius-type-rotors and also improves their self-starting ability and smoothness of operation. The support structure is mounted for rotation about a central vertical shaft (242) so that the rotor-deflector combination can be properly positioned. The invention also provides a partition plate (236) positioned between the rotors to give rigidity to the deflector plate.

A Savonius rotor assembly for interacting with a moving fluid, comprising: a support framework; a first rotor rotatably mounted on the support framework for rotation about a first central, vertically extending axis, the first rotor having a shaft, a top, a bottom, a height and at least two blades, each blade having an inner and an outer edge with respect to the first central, vertically extending axis, the blades positioned to allow fluid flow between the inner edges thereof; a second rotor rotatably mounted on the support framework for rotation about a second central, vertically extending axis, the second rotor having a shaft, a top, a bottom, a height and at least two blades, each blade having an inner and an outer edge with respect to the second central, vertically extending axis, the blades positioned to allow fluid flow between the inner edges thereof, the second rotor being positioned at substantially the same horizontal level as the first rotor; a deflector member, extending substantially along the heights of the first and second rotors and positioned on a side of the first and second rotors facing the direction from which the fluid is flowing, the deflector member including a substantially planar surface facing the direction from which the fluid is flowing, the deflector member having a width less than the horizontal distance between the first central, vertically extending axis and the second central, vertically extending axis and being centered between a first plane extending through the first central, vertically extending axis of the first rotor substantially perpendicular to a line drawn through the first and second central, vertically extending axes and a plane drawn through the second central, vertically extending axis of the second rotor substantially perpendicular to the line drawn through the first and second central, vertically extending axes.
