Lap simulations were performed for various CL/CD values using a
scaling factor and the results showed a significant lap-time
improvement potential, ranging from 4-6 %, comparing with the nonaero car’s version. Therefore the team decided to proceed with the
design and the implementation of its’ first aerodynamic package, aiming
for the maximum possible downforce while keeping drag as low as
possible for efficiency purposes. The amount of available motor power
was calculated through lap simulations, in order to determine the plan
area of wings and estimate the CL and CD values.
The aerodynamic
components consist of a
front wing assembly with
3 elements, which deflect
the air over the wheels,
and a two-element rear
wing. The wings are made
from a CFRP sandwich
construction, resulting in
a combined weight of 11
kg including mounting.
CFD simulations using STAR-CCM were performed at an estimated
average speed of 60km/h, which has been logged at earlier FS
competitions, and a higher average top speed of 100km/h.
