not to much. When it comes to wind and long term fatigue, usually a Reyliegh ( i think i spelled it wrong) distribution is used instead. PSUWind on youtube has a few videos showing this, but im not sure if they relate it to fatigue.

Hello, we are a team that operates Formula Student team in Korea. When we conduct the aero dynamics test, we conduct the experiment with only the aero parts without the actual car test. However, this time, we want to verify by logging the actual driving situation. The contents of the accelerator sheet are interesting, so could you allow us to receive the sheet and modify it? I want to develop it further.

Thanks. Curious how this would change IRL with wind included. I assume this vid is a 0 wind day. Let's say the wind is parallel, reduce or increase Fdrag or Dragx (N) by...? Do we simply include Vwind to the Fd...CdApV^2Vwind? Vwind could be + or -? Of course the results are real life so additional wind is included in your process, just not noted. But I was seeking the correct Fd that includes Vwind...

sorry for very late reply. the wind was close to 0 this day. However, if there is a wind, i would do 4 trials with a tail wind and a head wind, just to see how much it effects coasting velocity. If it doesnt really effect it, then i not adding it would be ok.

I also think it is important to mention that there is variability in the quality of part that can be printed. Different operators/printers may not have the same quality which will affect the surface finish, the pressure holding ability, the water permeability.
