To manufacture a device that is cost effective and robust, that can compete with the electric utilities head-to-head, dollar for dollar, without excuses, subsidies, rebates and resorting to exaggerated marketing claims. The true goal should be to compete against the power companies, not other wind turbine manufacturers. This requires a new design approach, such as the VAWT/AR. |
- The VAWT/AR might be considered a paradigm shift in the wind turbine industry, and is protected by U.S. IP rights.
- There is no new technology that has not been exploited to its fullest potential. It is not a matter of if, but simply a matter of when the extent of its utility is determined.
- We are being given an opportunity to introduce a new prime mover to the world simultaneous with the beginnings of a global energy crisis. Perhaps this is not a coincidence?
- This project has large implications for developing countries.

Blackhawk is a renewable energy research and design company dedicated to improving wind energy technology. It's first product, the TR-10, combines helicopter rotor technology with vertical axis wind turbines, resulting in the first major advancement in wind turbine design since 1931 (patent pending). 10 pre-production units have been manufactured and are out in the field undergoing rigorous testing. The company is poised to take it to the next level and is currently raising capital to be used for product hardening and improvement, R & D expansion into new products and overall corporate logistics.

(variables unique to the AR are in red)
- Rotor diameter/airfoil length ratio
- Airfoil aspect ratio (length to width)
- Airfoil planform (shape of lifting surface)
- Airfoil cant angle (currently 15°)
- Dampener response
- Rotor tilt/airfoil pitch ratio
- Rotor tilt/airfoil AOA limits
- Centrifugal tilt compensation

In pursuing the "Ultimate Goal"
- The VAWT/AR introduces multiple interactive variables that will allow for open-ended research towards advanced performance.
- The VAWT/AR exploits complex physical laws but can be implemented in a relatively simple mechanical device.
- The VAWT/AR has the potential to be manufactured very inexpensively, thus significantly reducing cost per watt.
- The VAWT/AR has the potential for longer productive life by producing power at lower RPM and higher torque, further reducing $/watt. [Horsepower = f(RPM x torque)]
