Pioneering Design of Wind Sail Receptors Rotor Blades
Wind Sail Receptor, Inc. is developing a
rotor blade design that could change how
wind turbines harness power. �We have
the major breakthrough,� said Richard
Steinke, President and CEO of Wind Sail
Receptor, Inc. �Our tests show that our
product provides three times more efficiency
than existing turbines.�
The Wind Sail Receptor�s Quad Blade
Construction uses Bayer MaterialScience�s
polyurethane raw materials to increase
durability and weatherability, while
reducing the weight of the blades and
maintenance costs.
The resulting polyurethane system offers flexibility and
resistance to the elements that is vital to the success of
Steinke�s design. Most rotor blades on the market are
made of glass-fiber or carbon-fiber reinforced plastics and
similar to an airplane propeller, according to the World
Wind Energy Association.
Blades made of those materials are vulnerable to cracking
or drooping after prolonged exposure to the elements,
Steinke explained. The airplane design
also doesn�t enable the best use of blade
surface, he said.
The unique design of the Wind Sail
Receptor blades improves their ability to
capture wind from as little as 5 mph up
to 50 mph, depending on the size of a
new technology for a variable generator,
Steinke said.
The Wind Sail Receptor�s design is also
more compact and lighter than existing
blades. Steinke estimates that a rotor
blade for a standard one-megawatt turbine
weighs roughly four tons and measures
100 feet. The Wind Sail Receptor blades will weigh no
more than a half ton each and have a measurement of less
than 50 feet.
Tests conducted showed that the blades will outperform
existing blade designs without the high-pitched whooshing
sound.
