Student Generation
quickly enough for them to design with, since
another key problem we face is that all our
simulations are run on our laptops.
This brings me back to the design judge's
suggestion that we do wind tunnel testing to
validate our CFD. The only problem was that
we were never able to actually access a wind
tunnel for testing, and since that was the only
official solution suggested to our validation
problem, we were on our own to come up
with a way to test.
We scoured the internet for solutions.
Flow visualization paint, made of paraffin and
paint pigments, seemed like a feasible way to
literally see what flow around the car looked
like-but we never quite got the mixture ratio
right, and Evanston weather was always a
little too cold, so all we really accomplished
there was staining the car fluorescent pink
and angering our teammates. Then we tried
taping yarn to endplates to see if flow within
our wings was laminar or turbulent-an arts
and crafts project that also ultimately ended
up as a failure.
It took us a few months, some Christmas
lights, and a couple of flashlights and printedout bullseyes, but we eventually came up
with a solution I'm proud of. We decided to
do a mock skidpad, with a circle 15.5 m in
diameter marked with cones and a taped-out
grid on the ground, and a drone flying above
to record speed. We told our driver to go at a

Before the aerodynamics team lines the car with printer paper bullseyes and holiday lights for
yaw angle testing, the driver checks with the rest of the team to ensure the car is safe to drive.
The aerodynamics and
bodywork package
made of "prepreg"
carbon fiber, a first for
the team after years of
wet layups, was cured
with construction
lamps, heat guns, and
vacuum pumps over
molds made from
MDF, fiberglass,
spackle, and laser-cut
cardboard, leading to
an overall weight
savings of over 40 lb.
