Newest breakthrough in true aircraft aluminum gulf wing blade design, simply the fastest, quietest, most durable blades made from REAL AIRCRAFT ALUMINUM. Great for low wind start up speed!
Smooth, fast, and well balanced. Advanced design for GM Delco alternators. All parts are water-jet cut to exact tolerances for high quality operation, and appearance. All aluminum and 1018 steel construction will withstand severe weather conditions.
Our blades are not made in someone's garage on the weekend. Missouri Wind designs and manufactures safe and reliable wind turbine blades in a real factory in Missouri.
The gull wing design has eliminated noise and cascade failure that all other aluminum blades suffer from. For extreme high speed that all PMAs require to put out any usable power. Extremely large pitches on aluminum blades is like an anchor not allowing the blades to cut through the wind like a knife. Falcon blades have very little pitch and are tested to 95 MPH winds.
WIND TURBINE BLADE FACTS:
Remember, bigger does not always equal more electricity! While the bigger blade sets do have more torque and thus turn easier in slower wind areas, they DO, however, turn SLOWER when compared to smaller diameter blade sets on the same PMA. Make sure this is what you really need or you could be sacrificing electricity in the higher wind areas since small blades turn faster. Of course we are again assuming you are using direct drive PMA’s here.
As an overall rule, larger diameter turbines will always make more power if they are optimized for a particular generator’s output with the proper gearing. Generally speaking, 8 foot is the largest diameter you can go with an economic direct drive system. After the 8 foot diameter range, blades spin so much slower that gearing makes better economic sense for operating most PMAs or generators. The other option would be to waste copious amounts of copper wire and expensive magnets making for a very wasteful, expensive and heavy direct drive generator or PMA design. It would seem that the 7 to 8 feet diameter range is the transition point between economic direct drive and larger geared systems.
THE “MORE BLADES” THEORY and ARGUMENTS:
Having lots of blades really gives you the best of both worlds. In low winds speeds, systems with 6 to 12 blades are a real power house! No argument here! They also have an advantage in super high winds since they can’t rev as fast so they end up actually protecting themselves by going slower than 3 blade systems would that either self-destruct or become very noisy! The more research we do with multiple blade systems the more we believe in the “More Blades” theory. These systems always come out on top out performing systems with fewer blades especially in high amp loaded conditions! Wind turbines experience “progressive loss” or cascade failure when under heavy loads. This means that the slower the rotor spins under load the MORE likely it is to spin even slower and so on (cascade failure) until the blades are moving so slowly they can’t catch enough wind to be effective anymore because of excessive “way-holes.” This is why two and three blade systems need a computer to keep the blades revved up to speed. The computer removes the load by making fast adjustments and this keeps the blades moving quickly eliminating cascade failure. However a computer is not necessary when you have lots of blades working for you since cascade failure is impossible with all of that surface area!
The slower a blade spins the more likely it is to spin even slower and so on until it can no longer adequately catch wind as “way-holes” form in the propeller’s diameter matrix area.
A potential power producing area of a wind turbine propeller’s diameter that is allowing air to pass through in-between blade strikes or the absence of a wind turbine blade in the wind’s path at any given point in rotation time that is usually caused by over-amperage loads including connection to lower voltage batteries used in low wind speed areas, high amperage appliances, or lack of blade area in the original turbine design.
IT ALL BOILS DOWN TO THIS ONE SIMPLE LITTLE QUESTION IN THE END
The REAL question becomes what is cheaper, extra blades or computer controls???
Well, at least in the case of small wind turbines it’s a no-brainer. Extra blades are much cheaper than electronic controls and definitely more dependable too – no computer electronics to fail! In the final analysis, more blades equals super low wind speed start up plus the added benefits of simplicity and dependability.
A final thought, the large commercial wind turbines use 3 large blades but they are also all GEAR DRIVEN, not direct drive, and use a computer to control the speed of the blades. Otherwise, the blades, if allowed to speed up in high winds, would simply explode. These type of turbines DO NOT REQUIRE HIGH SPEED TO PRODUCE POWER LIKE THE SMALL TURBINES DO.
Did you know our Falcon Wind Turbine Blades were used in the movie G.I. Joe: Retaliation?
You can see them in the underground prison during the Cobra Commander rescue scene. In the clip below you will see them in the background around 1:50, 2:14 and 3:05.
