Unveiling
Borealis
and the SVP team were welcomed by several hundred onlookers as the
Unveiling event opened on April 25th. The event featured speeches
by Dr. Patrick Starr (our faculty advisor), the Dean of the Institute
of Technology, and a
representative
from Storagetek. After the 3 speakers finished congratulating the
team on the completion of Borealis, the audience was invited to
take a first-hand look at the vehicle and the team members dispersed
themselves among the crowd to discuss the vehicle's design, production,
& racing with the spectators.
Design
Borealis
is the University of Minnesota's 5th generation vehicle.
Design of the vehicle began in the Fall of 1999. Since then,
every system on the vehicle has been carefully scrutinized; nearly
all of them have been redesigned. Almost every
aspect of Borealis hosts new innovations and ideas that can push
our vehicle's performance to new heights.
The
most visible change between Borealis and our previous vehicles is
the shape of the body. After refining the same basic shape over 3 generations,
we saw little margin for improvement with the same design.
Demanding higher performance implied a radical change in
the body; the Aerodynamics team responded with Borealis' new shape.

Another area of major improvement for Borealis is the solar array. Particular attention was paid to this part of the vehicle,
as it is critical in every solar car's success. After
more than 2 years of research & testing, we have selected different
solar cells, investigated new encapsulation techniques, and upgraded
our performance specifications for the power trackers (the electronics
hardware that regulates the solar panels). We
are confident that our new array will help Borealis shine!
The elegant `clamshell' chassis
& shell design that makes our previous 3 vehicles so distinct
will not appear on Borealis. Instead, the chassis
is integrated into the shell, making them 1 piece. This design is elegant in a different way, improving
our aerodynamics and saving weight. Borealis,
like Aurora II & Aurora3, is a 3-wheeled vehicle.
Our previous vehicles' suspensions have superb handling and
robustness. The mechanical team has been busy
at work, insuring that this history will be maintained in Borealis.
The electrical system, like the rest of Borealis, has seen a vast
number of radical improvements. The battery
selection maximizes efficiency and minimizes weight costs. Our choice of motor & controller reflects our commitment
to make no compromise in vehicle performance. The
telemetry, cruise control circuitry, and driver display systems
have all been rebuilt from the ground up. These
systems provide real-time information about vehicle status - critical
knowledge for racing Borealis at peak performance.
Racing

The team's passion for racing never wanes, even in the off-season.
Last May, the Borealis team raced Aurora3 in Formula
Sun 2000 in order to expose new team members to solar car racing.
