EAGLE TURBINES


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!!!

OUR BLADES WILL BOLT DIRECTLY TO THE AIR-X HUB
THE BOLT HOLES DO LINE UP !!
Increase your Air-X Production - Just by using 3 of our Blades even!!

AND, Our blades are quieter than than the Air's

HUB6 is now round with a 17 mm
center hole, and used for 3-blades also. If used with Air-X you must modify the tail section w/3 or 6 turbine propellers

Hub Only - #HUB6
$39.95

 


These blade kits also bolt right on
to our line of PMA's

 
 

NOTE: Hubs come with the very popular 17MM bore that fits most late model GM/Delco alternators

4 Packs of 12 Hardened Lock Nuts & Bolts (1.25" x 1/4"/20 NCT)
for Fastening Turbine Blades onto single hubs
$19.95  #EK124



4 Packs 12 Hardened Lock Nuts and Long Bolts (1.50" x 1/4"/20 NCT)
for Fastening our Wind Turbine Blades onto Double or Triple Thick Hubs (High Wind Conditions)
$22.95 #EK126


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

MAKE A SOLID 1500 WATT WIND TURBINE WITH THE 88" BLADE 6-BLADE SET BELOW AND OUR "MANTA" GENERATOR


88" INSTALATION INSTRUCTIONS

ALL model #BK / 88" and 86 " Now come with double thick sandwiched hubs!

NOTE: BLADES BELOW ARE NO LONGER BEING MADE, GET YOURS TODAY
BEFORE THEY ARE ALL GONE !!

     


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.

 
6 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.
