oberschlächtige

Oberschlächtige refers to a type of water wheel where the water enters the wheel at the top and flows over the top. This design is also known as a high-breastshot or overshot wheel. In an oberschlächtige wheel, the falling water strikes the buckets on the upper portion of the wheel, imparting a rotational force. The water then exits at the bottom of the wheel. This design is characterized by its high efficiency, as it utilizes the full potential energy of the falling water. The height of the water fall is a crucial factor in the effectiveness of an oberschlächtige wheel. Because the water is directed from above, these wheels are best suited for locations with a significant drop in water level, often found in hilly or mountainous terrain. The water is typically channeled to the wheel via a sluice or leat that directs the flow onto the upper circumference. Oberschlächtige wheels were commonly used in historical milling operations, sawmills, and for other industrial purposes requiring substantial power. Their design allows for a high torque, making them suitable for heavy machinery. Modern hydroelectric power generation has largely superseded the use of water wheels, but the principles of oberschlächtige design influenced early turbine development. The term itself is of German origin, directly translating to "over-shot."
