Fiberglass Wind Turbine
Blades
Please
NOTE:
| If you have e-mailed a blade inquiry
within the last year or so, and haven't received your
response - or follow-up replies - as to how and when you
can arrange to complete your Purchase and Pick-up of your
8 or 9 blade load --- Please send another E-mail when you
are ready for your blades. I've had constant
system failures over the past year or so and the last one
caused me to lose many e-mail addresses and names,
including several people who sounded as though they were
serious buyers.
|
I am truly sorry
to anyone who inquired and failed to receive my first
response -- and especially to those who were close to
receiving all the information they needed to travel here
and purchase their blade sets. Please write me
again if you still need blades. I haven't forgotten about
you and I am NOT ignoring your Project needs.

| E-mail |
And
again - NOTE:
| If
you have questions, other than Century Blade questions,
PLEASE setup your News Reader and visit: news:alt.energy.renewable There,
and a few other energy related groups, is where you'll
find answers to the intelligent, and the moronic alike.
Chances are that I won't or can't answer your Wind
Turbine questions. If the link above doesn't load the
news group for you - then you'll know that your News
Reader is not set up yet, or properly set up -- OR --
your ISP may not carry that particular group. In which
case, you should log-on to |
your ISP's newsgroup Support web
page or newsgroup and request that they ADD the group(s)
you want to their list. Also: you may never know WHEN
they've added the group(s) to their list - unless they
are nice enough to e-mail you - (doubtful) - OR - until
you Refresh said list....and that'll sometimes waste a
lot of your time downloading a list that may STILL be the
same as the one you've already downloaded. A popular
ISP's newsgroup list will usually be rather large. You
may also find the following energy group interesting. |

You're
looking at the upwind face of the
19' Century Blade.
Designed for clockwise rotation.
|
These
are USED commercial wind turbine
blades that used to fly on the turbine called
"Century". I do not have a fact sheet on the Century
unit, but was told that it was about a 100kW motor. It was an
upwind three blade unit with a twin tail. I've seen these blades
used on a 50kW motor in a downwind two blade design. The
"Century" units were removed from service to make way
for newer and larger turbine designs.
Once
used on the three blade Century hub, they do just fine in a two
blade downwind setup. Or you can use them in your own upwind
design. These blades can be used to harness the horsepower of the
wind for whatever your application needs. For Power Generation,
Compressed Air, Pumping, Grinding, Chewing, Crunching, Smashing,
Shredding, Sawing, Ripping, Routing, Milling or what have you.

Be
sure you don't confuse the Carter
turbine or parts mentioned here with
the Century Turbine Blades this site
offers. The Carter image and text is
only here for a visual comparison.

 |
The small unit, a Carter
Turbine, is pictured here only to show the approximate shape of
the "Century" blades. They are very similar in shape
and size but the "Century" blades are longer and have a
different type of; root/hub/flange setup. The Carter uses an
I-beam fiberglass spar which slides inside the rotor hub, as seen
below, and has the ability to "pitch up" and bring the
rotor to a STOP in overspeed conditions. The "Century"
rotor hub was a fixed pitch hub. I did not acquire any rotor
hubs, sadly, they went to the scrap yard, but your rotor hub
design has to fit your mainshaft anyway. The Century blade
mounting flange is easily adapted to / and any pitch setting can
be achieved.
Carter turbine rotor hub and blade cuff.
I do NOT personally
own ANY Carter blades -- but I may be able to assist you
with contacting the Owner of the few remaining USED sets.
However --- the last I heard; these USED blades have been
sold in the past for 1,500$US for a single 2 blade set.
The price for multiple sets of blades is 1,400$ per set.
(Prices are subject to change
without notice - on this website)
All blades are sold: (Used - As Is)
It is suggested that these Carter
blades be used Only
on existing Carter turbines - as Replacement blades -
as there is no guarantee that the internal parts will
still
be inside the blades - and your existing parts may be
required before operation...
(Note: There IS NOW a shipping
possibility available for this item)

certain purchases]

Carter
Blades (ONLY) E-mail
The Blade
Root is constructed of the same Carbon Fiber
material which is found in the Blade Spar. (see cutaway)
- Fiberglass construction with
steel root casing and mounting flange.
- Light weight and strong
- Aerodynamic design
- Hollow body
- Flexible
- Repairs easily
- Customizable

 Fiberglass blade
body construction:
One
piece blade body with aerodynamic leading
and trailing edges.
Hollow
construction throughout.
Hollow
carbon fiber rectangular spar, wrapped
inside and out with fiberglass. Total
length of spar is unknown at this time.
Spar
is 4-3/16 x 5-3/4 inches.
Blade
length is 17'-10 3/8". With the
root/flange it's 18'-11" total.
The
tip of the blade is 13" wide, and
this width runs for about 8', then it
slowly begins to widen for the remaining
9' 10-1/2" to the base/cuff which is
44 inches wide. This graduation in width
takes place at both the leading and the
trailing edges.
Steel root casing and
mounting flange:
Welded
steel construction with multiple gussets.
Tear-drop
shaped 12-1/2" x 10" mounting
flange 3/4" thick steel plate with
nine, 5/8" bolt holes for hub mount.
The
root casing is 6-3/4" dia. pipe
steel. Welded to the mounting flange with
8 reinforcing gussets.
There
is an upwind pitch built-in to the root
casing/mounting flange construction. For
those of you who need to know this pitch
degree, the measurements are;
12-1/8" upwind and 13" on the
downwind side. 7/8s' inch difference.
Leading edge:
Like
the wing of an airplane to generate lift.
The thickest part of the blade behind the
leading edge is 2-1/4" as measured
at the tip, running for about 8 feet
before the flaring begins.
Trailing edge:
Tapered
to a sharp edge like an aircraft wing.
Blade Cuff:
The
base of the blade is 44" wide and
convex towards the trailing edge (like a
reversed fan blade) to grab as much wind
as possible for easier low wind speed
startups. The thickest area of the blade
is 7 inches at the base, measuring next
to the root on the trailing edge side.

Blade prices have been dropped to $50.00 each when purchased in minimum lots of 8 or 9. If
your project uses a 3 blade rotor - then your number is 9 -- and
if your prototype uses a 2 blade rotor - your minimum number is 8
blades.
It's possible that I may
let myself be bothered for a 2 or 3 blade purchase - but that
price will be $125.00 each.
Some blades will take a bit more effort
to restore than others. Most of them can be flown as is or with
some minor glaze work - but they should all be painted for best
results.
If you have additional questions about the blades, corrections about any of the specs above, an
offering of ideas or suggestions on optional blade uses, or
problems with this page, please don't hesitate to write.

Original shipping/crating statement:
Crating and shipping is NOT a likely possibility at this time
(sorry). Sales of these blades will be restricted to those Who Can Drive to the Palm Springs CA area and transport the
blades for themselves.
NOTE: For some reason - most visitors to
this site either fail to read this Shipping section, or they
simply refuse to accept what's written here and continually
inquire about Shipping costs and methods.
So here's a shipping update: 12-23-04.
