Hi All!
It has been a while, but I'm following the thread from time to time
Plenty of interesting topics going on here, so I can't just step out completely.
Even though I decided to not compete for this year, but the car was (and still is) there. I've found a while to actually share some renders of "20 car. Paint was supposed to be with fancy colors I asked for during registrations, but with white more details can be seen. Here we go:
Honestly speaking I had completely different approach at the very beginning to get rid of problems from "19 car and make it better... "20 of course got rid of them, but produced much more new
therefore I went back to "19 parts to understand what and where things went wrong.
Some fun facts about the car:
- Main front wing flaps are build in the way that there's around 500 variables to play with (compared to around 300 on "19 car) and on top of that FW endplates, cascades and cuts come into play
- The rear wing flaps have less variables, but still each flap is built with 4 airfoils
- Every single part of the car itself seems to work better and is built in more efficient way in CAD...
- ...but the car doesn't work as supposed together (and now complaining part
)
- One of the main issue comes from FW wake, which hits the RW (but was not really supposed to)
- I was struggling a lot to bring the floor performance to the proper level
- The rake is still weird topic as 0,6 degree is the most efficient for this car
- Most of the base surfaces use "zero-size" approach, which also got hit me by recoil in some areas
- There were some crazy ideas for cooling system and floor tested, but no response in numbers was very suspicious...
For sure the car got over-complicated, also with some meshing restrictions seems like it got eaten by itself, yet many lessons learned
Just to mention that I still have some cool solutions in my head, however they were meant to be applied to the "ground-effect" regs, so... Let's see what future will bring!
Meanwhile: Good luck for everyone with this race, and next ones!
