Build Your Own Wind Turbines with our Blade Sets
Or,
have an emergency set available at all times for your Eagle Turbine!
Start
Your Own Wind Turbine Manufacturing Business with
Our Inexpensive Carbon Fiber
Enhanced Wind Turbine Blades. These second generation blades feature a razor
sharp edge which is delicate. Rough handling will flatten this edge
and may cause degradation of performance. The razor edge makes them extra silent
and extremely powerful! (Trailing Edge)
If you wish to dull, sharpen,
modify or finish the edges of these blades you may only use 325 mesh wet &
dry sanding paper. You must wear heavy leather gloves when handling or sanding
these sharp blades!!! | |

88"
Diameter High Performance Turbine Propeller Kits!
This design
provides the best of both worlds! Thin tips for high speed rotation and thick
inner blades that catch wind efficiently for high starting torque.
Our
new aluminum blade extension kits will turn the stock 59" diameter #HWB series
blades into a massive 88"diameter rotor! This will not work good for Eagle
wind turbines but will enable you to design and build inexpensive low wind speed
turbines with our super core PMA's or even one of your
own generators or alternators. 17mm
hub center fits 99% of GM/si alternators

THESE
KITS ARE FOR EXPERIMENTAL WIND TURBINE PROJECTS, NEW INVENTIONS, WATER PUMPING,
AIR PUMPING OR FOR REPLACING
BLADES ON OLDER WIND TURBINES THAT ARE NO LONGER MANUFACTURED.
NOT
FOR USE WITH EAGLE
WIND TURBINES!!!!!!!!!!
SINCE BIG BLADES TURN TO SLOWLY!!!!!!!!!!!!!!!!!!!! 17mm
hub center fits 99% of GM/si type alternators but you can weld on any sized shaft
adaptor you wish The airfoil of these extension
kits is harmonious with the dynamics of our standard HWB series blades. The maximum
wind speed rating on the blade extension kits is about 90 MPH (down-wind) while
stalled or 110 MPH while rotating. Surprisingly the centrifugal force of a rotating
propellers supports the hub assembly from folding in storm force wind conditions. These
combinations are great for making low wind speed turbines that are targeted and
optimized for wind zones in the 5 to 12 MPH range assuming direct drive PMA's
are used. 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 a 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 PMA's or generator's. 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.

Eagle Blades - Good for 4.7 MPH Startup Winds & above (Depends
on PMA & Wiring)
Higher voltage turbines will start
producing a couple amps at low wind speeds
Cut In Speed is determined by your PMA, Wire, Battery Size and State of Charge ! |

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 less 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 slow 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 rev'd 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!
"Cascade Failure"
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 propellers
diameter matrix area.
"Way-Holes"
A potential power producing area of a wind turbine propellers diameter that is
allowing air to pass through in-between blade strikes.
or - The absence of
a wind turbine blade in the winds path at any given point in rotation time usually
caused by over-amperage loads including connection to lower voltage batteries
used in low wind speed areas or 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 benefit's of simplicity and dependability.

WARNING:
ALL of these blades are very sharp and can cause severe injury if handled improperly.
Treat these blades with the same respect you would have for a sharp sword.
The Eagle wind turbine blade sets can turn at well over 2000 RPM on a windy
day and can cause severe bodily injury when they are spinning. Use extreme caution!
Never mount or work on a wind turbine on a windy day. Never place a turbine in
any area that can be accessed by inexperienced persons or children.
We assume
no liability for ANY injuries caused by these products. | |
