I'm interested in if anyone has any information into these types of wings in Formula racing (not just F1, and not just the current T-Wings), and what the expected gains conventional wings have over this. When I see the group of C-Wings in the CoD graph, the low drag ones at the beginning of the list seem that they could be inverted and used as front wings.
So, a few questions:
1. Do these types of wings work in ground effect?
2. Would these types of wings reduce drag in current Formula car design?
3. How different would a Formula car look if these types of wings were required?
Thank you!
