Does anybody know if the Indycar races have considered the introduction of a DRS?
Or is DRS used in a different racing category than Formula One?

Not quite. Aero neutral isn't the same as zero drag. FSAE cars are very lightweight and there's no straights of note, so the improvement in performance tends to outweigh the loss in fuel economy, hence why everyone's running a big aero package these days.Paul wrote:With active aero though, you can get the best of both worlds. Only real drawback is added weight, otherwise down-force producing elements can remain aero neutral in shape on straights, form air brakes in braking zones and provide exactly as much down-force as needed in any particular corner, in theory at least.
Yeah, this is true, I read in Race Car Engineer that aero is worth about 8 seconds of track time (could be wrong), which outweighs the actual fuel economy in the long run anyway, and because there's no parc ferme as such(again could be wrong), you can literally move all your wings to give as little drag as possible on your economy runandylaurence wrote:Not quite.

The results of my CFD analyses were the following:We had two aims by introducing this system
- Performance increase at low cost
- More work for the driver to better train them to F1
- Strategy during the races
- Increase of the overtaking possibilities.
It worked on the four points, so we are happy with that.

Nice suggestion. I was thinking the same thing when i read the whole post. One thing is that i am bit late to reply in this thread but I hope this would be OK.mep wrote:Hi Tom,
In my opinion when you manage to do some CFD then you don’t need to talk about the used materials and manufacturing process anymore. That is just a totally different topic and has been done many times before. Just focus on 1 thing. On the other hand doing the CFD can be challenging if you have never done something like this before so be careful with that.
The rules you can get from the FIA homepage.
You don’t need to use exactly the same profile the F1 teams use. Have a look at some profile database available. Or check what Simon McBeath describes in his book “Racecar Aerodynamics”.
