 The Vertical Axis Wind Turbine Articulating Rotor
TR-10 (patented)
The Blackhawk Tilt Rotor VAWT/AR is changing the landscape of alternative energy and the access individuals have to it. The TR-10 will allow the average user to access up to 1.2 kilowatts of wind-generated power, lessening their dependence upon coal-fired, petroleum burning, hydroelectric and nuclear power plants.
With efficiencies in advance of the older style wind mills, and with much lower, self-starting cut-in speeds, the Blackhawk VAWT/AR allows its owner to realize clean energy generation at times when other individual wind energy systems are just marking time. Push/pull rods change the pitch of the solid "sails" in the same way helicopter rotors, turboprop propellers and standard windmill rotors do, but without any of the complicated electronic control systems.
The dampened Articulating Rotor, a design which allows the entire turbine to ‘lean into the wind' to generate and retain higher torque at lower RPMs, develops greater amounts of power as wind speed varies.
The aesthetically pleasing, extremely quiet and easily zoned Blackhawk is also bird-friendly. |

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 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 can 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)]
- The VAWT/AR may be considered a paradigm shift in the wind turbine industry and is protected by U.S. IP rights.
- The VAWT/AR is a new technology which 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 full potential and utility is determined.
- The VAWT/AR project has large implications for developing countries.

The national average for energy consumption, is +/- 1.5KW instantaneous average, or ~1095 KWh/mo (1.5KW x 720 hrs/mo). Just like in real estate, the top 3 things to consider are: location, location, location - specifically regarding AVERAGE WIND SPEED. You can't calculate your AEO (annual energy output) based solely on the NREL or AWEA average wind speed recordings in an area. Typically in the Lower 48, the statistical wind power distribution is a Wiebull Distribution with a form factor of 2, which is called the Rayleigh Distribution.
The occasional very windy conditions contribute more to the overall energy production than the average wind conditions. This is due to the fact that the energy in wind is a function of the cube of its velocity, so every time the wind speed doubles, you get 8 times more power.

Wind Action Overview
- Wind causes Rotor Tilt
-
Rotor Tilt sets Airfoil Angle of Attack (AOA)
-
Airfoil AOA creates Aerodynamic Lift
-
Aerodynamic Lift creates Rotation/Torque
-
Additionally, there is a simple means of correction for gyroscopic precession built in.
