Introduction

Vertogen have developed the mechanism to create a Unique VAWT that not only has Variable Pitch but includes adaptable and adjustable pitch control system with a fully mechanical integrated governor. This equates to a Turbine that can be tuned to start easily, operate at a Given RPM without any external Control Automatically.

Known Problems with other VAWT Turbines

Starting – Efficiency – Control – Reliability – Flexibility – Safety – Narrow operating conditions

WHAT PARTS CAN WE SOLVE ?

ALL OF THE ABOVE !

HOW

Although many efforts have improved the VAWT by New Materials, Blade Design and some minor design changes NONE have addressed all of the above.

The key is to develop a Pitch system that takes full advantage of aerodynamic lift and drag properties coupled to an Integrated Governor.

Create a mechanism that creates lift from Multiple Blades and reduce drag from the remaining ones in the acceleration mode and to reduce RPM create drag from multiple blades.

Integrated with our Governor the VAWT operates Autonomously.

The VAWT is fully mechanical and needs no external electric or mechanical devices. Keeping the unit Simple to install and safe in operation.

Starting

Our Variable pitch allows easier starting at low wind speeds.

Efficiency

Because our VAWT produces energy when other turbines most are stationary due to LOW or HIGH wind conditions and it produces more torque.

Most Designs normally get lift from one blade and drag from other blades. Our design takes lift from multiple blades and minimizes drag from the none performing blades. When the operating RPM has been reached all blades have minimal movement. The governor constantly monitors the RPM and will apply the changes, positive or negative pitch when the VAWT is operating outside its predetermined RPM.

Control

The VAWT can be tuned to operate within a chosen operation environment, When to start, operate at a pre-determined RPM, Reduce RPM Automatically.

Reliability

Pitching the Blades correctly at the appropriate position within the Rotation Cycle and limiting RPM reduce stress and vibration through all components. 5 Blades also reduce pulsing like two, three or four bladed Units. The Generator
will output a more stable Voltage to the Charge Controller.

Flexibility

Pitch and RPM Control can be adjusted to allows the Turbine produce more torque. Operating RPM can be adjusted to
work with different devices like Permanent Magnet Generators (Electric Generation) and Mechanical devices like Pumps, machinery, compressors etc.

Safety

High Wind Conditions. The Integrated Governor will control the RPM. As the RPM exceeds the operating chosen limits. Using the Advantages of the lift technology to increase RPM we reverse the pitch mechanism which deaccelerates the VAWT. Our VAWT can operate in Low and High Wind Conditions. I.E operate when others at Stationary.
