I have further researched a swan neck wing design. I plan on using an E-423 air foil using a 40cm chord length. This is because of the reynolds number I have calculated to be rather high in the 1 million range. At this range an angle of attack from -5 to 15 degrees is optimal. Anything past 12 degrees creates more drag which is essentially stalling the car. The optimal angle for Cl/Cd v Alpha is 5 degrees in a theoretical 2D simulation.
Here are some rudementary sketches that I have created.
ALTERNATIVES
Some alternatives I have thought about are to make the wing bottom mounted instead of a swan neck. I feel that I would not want to pursue that route because having supports under the airfoil will disrupt the airflow underneath the wing especially around turns. The whole purpose of the swan neck wing is to perform better than a traditional wing around a track.
This design will closely respemble the GT3RS wing however it will not include the active aero for braking.
I will continue to create models for this to be ready for a 3D simulation. For the CFD the program I would like to use is Ansys. I have some experience with Ansys and would like to sharpen these tools along the process.

Hi Jarod, This looks really cool. I think that the active aero might be too hard as you stated.
Hey Fin thank you for your reply. In the future it will be something I would want to look at more.
This is so close to one of my first ideas that I had. I wanted to create a 3D design of an active aero DRS wing with fushinon 360. I was then going to 3D print the pieces, attach a wire and use a motor to flip the wing. But this idea is so cool to see, do you plan on 3D printing it at all?

Hi Andres that is really interesting. I just posted my renders for the wing and was wondering how you went about making it active aero? Were you planning on making it create more drag on braking?
I liked how you have the diagrams of the resistance of the wind I think it help with understanding why one might add this to a car. I know you mentioned different designs of mounting the wing on the top or on the bottom what aesthetic would you say the wings would represent? Also are you going to keep the design completely digital?
Hi Sophie thanks for the comment. I plan on making a physical wing that will be mounted onto the car in the future. I am not too sure how the timeline will workout but I will try to get it finished by the end of the semester. I think this aesthetic would be close to a BŌSŌZOKU aesthetic on older Japanese cars. These were more nonfunctional designs and just for looks. I think my design will add more functionality.
