WIND GENERATOR COMPETION RULES
Power must be generated solely by wind from the competition fan.
You must use the wind turbine generator provided by GCSU as the sole
power generator for your wind turbine. You must also use the 12-hole
crimping hub provided by GCSU. Each team should bring theirs to the
The judges must be able to verify that the correct generator and hub are
being used on your turbine. If the judges cannot verify that the generator is
the correct one your team may participate—but will be unable to win any
You may attach any of the following items, which GCSU will provide
Various weights and types of paper, including bond paper, card stock
and construction paper.
1/2” Styrofoam sheets
Coffee stirrers and popsicle sticks (for supports)
Masking and duct tape.
Different weights of cardboard.
If you wish to use other materials, you must ask your teacher to contact Dr.
Deneroff, and a decision will be made as to whether it can be provided. All
contestants will have access to the same materials. Deadline for requesting
additional materials is May 1, 2011.
Wind turbine blades must be made by your team out of the materials
provided at the competition.
Your turbine can be vertical or horizontal axis.
Your wind turbine must be free standing. You will be provided K’Nex in
order to make a tower for support.
How will we performance test your wind turbine?
Your turbine will be tested using a single box fan on high speed.
Prior to performance testing, student teams will be given a reasonable
amount of time to test their devices. This will give you a chance to evaluate
the conditions of the space.
Once the testing session begins you will be given two minutes to set up
your wind turbine.
You must have two wires at the base of your turbine. You must label which
wire is positive and which is negative. These wires will be attached to a
circuit with a 10 ohm resistor (light bulb) in series and will simultaneously
measure voltage and amperage.
In order to receive full marks for your turbine’s functionality, your wind
turbine must be able to start producing power once the fan is activated,
without external assistance.
If your wind turbine slips, breaks apart, or falls over before the 60 second
timer is started, you will either be given two minutes to set up your wind
turbine again, or you will be allowed to remove the turbine to make repairs.
In that case, you will be moved to the back of the line for retesting.
You will only be given one restart opportunity. It may be granted before the
60 second test begins, or once it has begun—but not both!
We will collect power output data for 60 seconds. Your energy output score
will be calculated using a multimeter.
Local judges have final say on rulings and protests.
Who has to show up?
To be eligible for the competition, all members of your team must be
present on the competition day. You may have up to 2 alternates as team
members. Exceptions include:
some, or all, of your team members are unable to attend
because of a scheduling conflict with a school sanctioned trip (a
signed note from the advisor is required)
a team member cannot attend due to illness or family crisis (a
signed note from the team coach is required).
How will your turbine be judged?
Design & Documentation (35% of score)
A panel of judges will examine your wind turbine design before testing it in
the wind tunnel. You must be prepared to discuss/defend the choices you
incorporated into the design. The design criteria you will be judged on
include: the choices/mechanisms by which you maximized power
output, the craftsmanship of your design, creativity, and environmental
decisions (eg. did you use recyclable materials can you easily take your
turbine apart after the competition and reuse the parts?).
To aid the judging process, students should produce some type of research
documentation that reflects the design process. They may:
write a short report
create an engineer’s notebook
make a short video
create a poster
Students must provide the means to play a video or DVD, or run a slide
show/power point, etc. We will not provide a computer or other device. This
document may introduce the team and the wind turbine they constructed.
Some things to include in this documentation may include:
school they hail from
innovative & creative elements of their design
design problems they faced
issues with wind power and its impacts
how “real” wind turbines work
Energy Output (65% of score)
The total energy output of your turbine over the 60 second trial period will
be collected. Your team’s energy output will be ranked relative to other
competitors. Each team will receive points corresponding to their rank. The
turbine with the highest energy output (milliwatt-seconds) over the 60
second trial period will score 65 points.
Energy output score based on rank
1st Place = 65 Points
2nd Place = 60 Points
3rd Place = 55 Points
4th Place = 50 Points
5th Place = 45 Place
