Two walls Savonius type scoops of a under water turbine

May 29, 2012 / HYDROKINETICS

Windmills, generally, come in two types: horizontal-axis wind turbines (HAWTs) and vertical-axis wind turbines (VAWTs), with HAWTs being the most common. Horizontal-axis wind turbines (HAWT) typically have the main rotor shaft and electrical generator at the top of a tower, and must be pointed into the wind. Small turbines may typically be pointed by a simple wind vane, while large turbines generally use a wind sensor coupled with a servo motor. Most have a gearbox, which turns the relatively slow [...]

One of the main problems in exploiting ocean currents effectively is the practical operation of marine turbines under real ocean current conditions. For example, the simplest and the most rational configuration for marine turbines employ a conventional axial turbine with a rotor driving an in-line generator directly or through a gearbox. The water turbine has the advantages of simple structure, reliable operation and high efficiency, and can be arranged on a river with wide river surface and gentle river flow, [...]

How easy is it to harness water flow energy ?

January 23, 2012 / HYDROKINETICS

The main disadvantages of such conventional sources of energy are that they are rather unpredictable (wind, ocean waves, solar energy), or can provide only periodic generation of electricity (only two times a day in the case of tidal currents and only during day time in the case of solar energy). As an obvious example, wind frequently changes direction and can quickly change from dead calm to hurricane gusts. These wide variations in power availability represent highly probabilistic processes. Accordingly, currently [...]

Tandem co-rotation rotors of a horizontal axis turbine with 2 two bladed orthognal propellers

January 15, 2012 / HYDROKINETICS, WIND TURBINES

The distance between the two rotors measured by the common shaft is about 10 percent of the upfront rotor diameter. The second rotor is 15 percent longer than the diameter of the first rotor ( the spacing between the rotors automatically varies ). At low speed flow, the distance between them is minimal; at high speed flow, the distance is increased by 35% from the diameter of the first rotor. Thanks to this configuration, the tandem wind propellers rotates efficiently [...]

Tapered propeller for low speed flow

January 15, 2012 / HYDROKINETICS, WIND TURBINES

In the video you can see a tapered propeller for low speed flow. The pitch angle, which is near to the shaft, is above 45 degrees. In the periphery of the blade the pitch angle is about 5 degrees. The blades have a very thin profile – about 8 to 9 percent of the blade horde. The profile is highly chambered. It’s manufactured by a light material – carbon, for example which brings efficient operation at a low wind stream. [...]

A simplified concept model of 3D Jet rortor of an axial flow turbine

January 15, 2012 / HYDROKINETICS, WIND TURBINES

The demo model (shown at video) is not to shape and to scale. The 3D turbine with diagonal inclined tapered JET blades operates very efficient in very broad range of flow speeds and starts to rotate by itself at a very low flow speed achieving much better performance. By 3D rotor is harnessing much more flow stream energy in comparison on the well known prop / impeller turbines. In addition we find out that the speed of flow passing near [...]

Newly invented axial flow tandem rotor turbine rotates at ultra low flow speed

January 15, 2012 / HYDROKINETICS, WIND TURBINES

New invented horizontal axis (inclined axis) rotor is applicable on both wind and hydro-kinetic applications at low speed water flow (slow moving water stream). Because of the rapid and highly non-linear relation of the power output and the wind speed, to develop the shown Low RPM High Torque Small Wind Generator with two Co-rotating rotors, we have taken a special care in designing the windmill rotors (Blades), generator system and the yaw system to meet with our requirements.
