Enclosed vertical axis fluid rotor

摘要

A enclosed vertical axis fluid rotor used as a wind turbine of two designs having multiple sails that are concave on the inside and convex on the outer side which allows omni-directional wind or other fluids to engage sails to create optimum fluid momentum. These are sectional segmentation of each rotor that can be stacked upon one another at locating lug points to be attached to each rotor to keep radial alignment precise during assembly. The preferred embodiment would be of composite materials or plastics that can be molded to a given design of three or more stages. The advantage of this turbine is using the fluids to their optimum efficiency. These designs have low starting speed, low precession, and low drag. One design has a central axis that turns with bearings with the rotor and the other design is a central static (non-turning) axis shaft that allows the turbine to turn on bearings.

主权项

1. A fluid rotor, comprising:
a shaft that rotates about an axis running from a first end of the shaft to a second end of the shaft; a blade assembly attached to the shaft, the blade assembly including at least three blade stages, each blade stage comprising:
at least three blades in a configuration that locates each blade at equal distances around a central axis of each blade stage, each blade having a shape that is a convex airfoil extending from the central axis of each blade stage in a radial direction with a concave back, the shape allowing fluid to push on the concave side of each blade, and pull on the convex side of each blade;an upper plate attached to an upper portion of each blade stage, the upper plate including a central hub for receiving the shaft, and attaching the upper plate to the shaft; anda lower plate attached to a lower portion of each blade stage, the lower plate including a central hub for receiving the shaft, and attaching the lower plate to the shaft,wherein said at least three blade stages are stacked to align the central hub of each upper plate, the central axis of each blade stage, and the central hub of each lower plate with the axis of the shaft; an upper bearing mount attached to the first end of the shaft; a lower bearing mount attached to a base, the lower bearing mount receiving the second end of the shaft; and a set of braces in a configuration that locates each brace at equal distances around the axis of the shaft, a first end of each brace attaching to the upper bearing mount, and a second end of each brace attaching to the base.
