WINDMILL WITH VERTICAL AXIS OF ROTATION Russian patent published in 1994 - IPC

FIELD: wind-electric power engineering. SUBSTANCE: windmill has rotor 1 rotating about vertical axis 2. Shafts 3 mounting turning blades inclined through angle ϕ to the vertical are attached to rotor. Each blade is joined through flexible member (spring 5) with end of adjacent shaft and is mounted for turning through angle v+90 deg. in one direction when flexible members oppose their turn and through angle of 90 deg. - v in opposite direction when flexible members do not oppose their turning. EFFECT: improved design. 1 dwg
