With the 2019 season now concluded, and jjn and I being in stage 4 withdrawals right now, we figured that we needed "something" to keep our mi... ooooooo!! Is that the 2021 regulations???
So, without further ado, I would like to present to you all our first, and legal (to the best of our knowledge), 2021 spec. F1 car!! And the first car that is wholly of F1T design!!
-sigh-... who would have thought that Aerosaruman and Aerogandalf would ever work together again, huh?
What forum post from Vyssion would be complete, without some CFD: COLOUR FOR DIRECTORS!!
Very similar setup to the Perrinn model; straight ahead solve here, no crossflow or curved flow, steady-RANS w/ SST turbulence inc. wall functions, 31.5million elements, etc etc...
Here is a list of bullet points that, so far, we have twigged, and are gonna work on next. Now I am gonna shamelessly make excuses for any "iffy" performance or flow features you see, because... IT WAS OUR FIRST GO AT IT, OKAYYYY?? Overall, for a first go at it, the car performs very, very well; hats off to jjn.
- CzS = -4.95
- CxS = 1.80
- Front Wheel wake is pretty crazy now... we will work on this
- Going to reduce pitch setting of FW flaps
- Inboard floor fence vortex isnt under control (just spreads out)
- 2021 Force Breakdown = Floor (50%), FW (37%), RW (25%)
- Compared to Perrinn = Floor (55%), FW (30%), RW (40%)
- Higher than 100% is due to Lift generated on the chassis and wheels (6% lift on 2021 wheels, 9% lift on Perrinn)
- Balance of 2021 is ~49% which is quite far forward, so we will correct this (starting with FW flaps as mentioned above)
- Surprisingly large amount of low pressure below the car
- Front suspension is stalled
- Top of floor inlet is stalled
- Rear of Lower sidepod expansion has stalled
- RW flap stalled in curved EP sections (and slightly along TE) and RW as a whole is very draggy
