The Savonius wind turbine is a simple vertical axis wind machine invented by Sigurd J. Savonius in 1922. In its original design, it was made with two half-cylindrical blades arranged in an 'S' shape. The convex side of one half-cylinder and the concave side of the other face the wind at the same time as shown in Figure 26.

Vertical axis wind turbines (or VAWTs) have the main rotor shaft arranged vertically. Key advantages of this arrangement are that the turbine does not need to be pointed into the wind to be effective. This is an advantage on sites where the wind direction is highly variable. VAWTs can utilise winds from varying directions.
Depending on your application, add-ons such as pallet systems, 2-axis CNC heads, tool and part probing, and various tooling designs can be engineered for the machine as well. Over the past 30 years, we have provided more large vertical turning and milling machines than any other manufacturer in the world.
A CNC vertical mill machine has cylindrical cutters oriented vertically on a spindle axis. This is especially useful for plunge cuts and drilling; these tools are considered to be the best for diesinking applications. With CNC technology, the tools in some vertical machining centers can be manipulated on up to five axes for the fabrication of ...
MILLING MACHINES. Wherever equipment repair applications involve milling critical mounting surfaces, we have a precision machine that can be perfectly configured to fit. Our portable three-axis milling machine family starts with the PM4200 – a versatile model with available bed options of 20, 49 or 78 inches (508, 1244.6 and 1981.2 mm) of travel.
The other design consideration investigated in this paper is the design of the blade support structures. In Ref. [], the impact of various strut configurations on the efficiency of vertical-axis turbines has been assessed.Now in this paper, two interesting and most revealing turbine designs from Ref. [] are chosen to investigate the effects of the struts on the wake recovery.
From the universally applicable vertical versions to the 5 axis vertical machining centers, every machine has automatic tool changers and state-of-the-art CNC control technology. From portal milling machines with large traverse paths to compact machines with small space requirements, find a right solution at KNUTH Machine Tools.
The vertical waterwheel was one of the most important sources of energy to be developed. Invented a century or two before the time of Christ, it was a major turning point in the history of technology. ... enabled man for the first time to use an inanimate power source for industrial production and it had this major impact on technological and ...
In CNC machining, the direction of rotation of the milling cutter is generally constant, but the feed direction is changing. So, there are two common phenomena in milling: climb milling and conventional milling. The cutting edge of the milling cutter is subjected to an impact load on each cut. To complete successfully in milling, it is ...

Vertical shaft impact crusher These crushers use a high speed rotor that has its axis along the vertical axis. The vertical-shaft impact crusher can be considered a stone pump that can operate like a centrifugal pump. The material is fed through the center of the rotor, where it is augmented to high speeds before being
You may have seen this photo online recently of EDF's floating offshore vertical-axis wind turbine (VAWT) called "Vertiwind." It has a nameplate capacity of two megawatts. The Vertiwind will be part of EDF-EN's offshore wind farm project called Inflow, which the European Commission is helping fund. The strange design piqued my curiosity about VAWTs. Why…

H-Series impact mills can handle up to 240 tons per hour and are reversible for extended wear life. The H-Series cage mill is engineered and constructed to operate at or near-peak efficiency longer, providing a greater return on capital investment over its life than competing equipment.
The earliest documented windmills were vertical axis systems, with vertical sails made from reeds or wood that was attached by horizontal struts to a vertical shaft with a stone for grinding purposes. The first windmill to appear in Europe was the post mill with a horizontal axis system, with a four-bladed mill attached to a central post.
