The patent relates to fluid machines that serve different purposes. Turbines are generally divided into two types: resistance and lift runners. The rotational speed of a resistance runners rotor blade can never exceed the flow velocity, regardless of whether the medium is air or water. While most wind turbines are lift runners, this principle has yet to be adopted for water turbines. Classic water turbines, such as Pelton, Francis, and Kaplan turbines, are resistance turbines that use water pressure to convert flow energy into rotational energy to generate electricity. However, they have a serious drawback: they impact the free flow of water and the river ecosystem. They also require complex and costly construction. At RES, we have developed turbines that can be integrated into river courses without the need for dams. This enables kinetic energy to be converted directly from flowing water. To enable this in slow-flowing waterways, the water turbines presented below are designed as buoyancy turbines. They use an asymmetrical blade profile that provides approximately one-third more lift than a symmetrical profile. According to our design, all of our water turbines have adjustable nose and trailing edge segments that are hinged to a load-bearing steel blade segment in the shape of a hollow box. This ensures that the suction side of the asymmetrical blade profile is always aligned with the flow direction, both upstream and downstream. The video shows horizontal rotor rollers integrated into a bridge structure that spans a river without obstructing it.

The RES water turbine uses electromechanical actuators integrated into the blades to adjust the rotor. The suction side of the blades always faces the direction of the flow. Fish can safely pass through the turbine rotor in both directions. In this example, the vertical rotor modules are integrated into a bridge structure. Other examples demonstrate the potential of the buoyancy runner principle for run-of-river power plants in inland waters, tidal power plants in suitable coastal areas, and underwater hydroelectric power plants. The rotor blades consist of front, middle, and rear blade segments. The middle blade segment is designed as a rigid longitudinal beam of the rotor blade. At diameters P and P, the suction side of the blade profile changes regularly with the flow direction.

The rotor modules can be anchored at the bottom of a flowing watercourse or on the seafloor. There, they convert the flow into rotational energy. Many large rivers, such as the Nile, the Amazon, the Yangtze, the Mississippi–Missouri, the Huang He (Yellow River), the Ob–Irtysh, the Amur, the Ganges, the Lena, the Congo and the Mekong, carry water towards the sea that remains largely unused. Waterways on Earth's surface represent an untapped energy source. With underwater buoyancy runner technology, it is possible to extract energy from rivers without negatively impacting the ecosystem. Tidal currents represent a second largely untapped energy source. The underwater topography of the continental shelves amplifies tidal currents, allowing them to reach considerable speeds. This is precisely where RES's proposed underwater turbines could be used for energy generation.

The Energy Chain, dedicated to the 17.4 million people of the Netherlands, published its first post of the year. At high tide, the Oosterschelde is dammed up; at low tide, water flows into the North Sea at high speed. Between the piers of the barrage are drums containing six adjustable rotor blades each. These blades, driven by the current, are connected by intermediate rotor discs to form a shear- and torsion-resistant frame girder with a nine-meter diameter. The rotor drums, with their adjustable blades, rotate at speeds up to five times faster than the current. If channeled through the existing barrage, they could generate an unlimited amount of energy. When the P–P′ diameter is perpendicular to the flow direction, the suction side of the asymmetrical blade profiles alternates between the inside and outside of the orbit. This causes the asymmetrically profiled blades to generate propulsive forces tangential to the flow in the flow-oriented and downstream halves of the orbit.

A series of water turbines could be installed at the Oosterschelde Barrier. Each turbine features a funnel-shaped diffuser, also known as a diffuser stage. This advanced Wells turbine, with a flow diameter of six meters, maintains its direction of rotation when the flow direction changes due to the ebb and flow of the tide. Each turbine unit generates around 500 kW of continuous power. Assuming hundreds of these turbines could be installed, the total output would range from 50 to 100 MW. The turbines ring generator is integrated into the bridge structure, and the stator and rotor are accessible via a maintenance walkway. The rotor blade has a central wing segment that connects it to the rotor and a flow-through hub. The hub is designed as one of the turbine wheels six spokes. Adjustable nose and trailing edge segments are hinged to each spoke. Synchronizing the adjustment of these segments creates an asymmetrical wing profile that can be aligned with the flow at a positive angle of attack during ebb and flood tides. The positive angle of attack causes the asymmetrical wing profile to generate a high lift force in the direction of rotation, converting the waters kinetic energy into rotational movement. A variable, asymmetrical blade profile is superior to a conventional turbine blade when the flow direction changes regularly. The confuser and diffuser stages use the nozzle effect to accelerate the flow velocity by narrowing it at the inlet and creating suction at the outlet.

Energy can be generated wherever there is flowing water. A floating turbine consists of a float that houses a generator. The generator is connected to an underwater rotor via a shaft. The top of the float is covered with photovoltaic cells. The rotor blades are connected by ring beams at their upper and lower ends, and they are arranged at a radial distance from the shaft by tension spokes. The suction side of the rotor blades has a variable, asymmetrical foil profile. Integrated actuators within both halves of the rotor align it in the direction of flow. The rotor is divided by diameters P and P.

This embodiment of the invention comprises two vertical-axis rotors connected to a float. The float is anchored to the riverbed or seafloor and automatically aligns with the current. These water turbines can be manufactured in different sizes and are suitable for seasonal operation on rivers that freeze over in the winter, such as the St. Lawrence River in Canada. This type of energy generation is environmentally friendly and allows the turbines to be maintained during the winter months. #reswt7 #reshydropower #resfloatingturbine #resfloater #resewing #resblade #fishfriendly #waterturbine #electricity #energy #energybooster #mechanics #hydrodynamics res-institute.com
