Back when DRS was first introduced (and the allowed angle change was less) a smaller flap was a good way to make it more effective (shed more drag).
If I'm not mistaken there wasn't a fixed angle change for the DRS flap, but a fixed distance for the edge to travel, that's why a shorter flap was beneficial. If the fixed measure was the angle change, a bigger flap would shed more drag.Sevach wrote: ↑Thu Sep 13, 2018 11:42 pmBack when DRS was first introduced (and the allowed angle change was less) a smaller flap was a good way to make it more effective (shed more drag).
Over the years rules changed and teams moved away from this style, maybe Haas is bringing it back for a couple KM/H at the end of the straights.
Kinda surprising that Haas has been more aggressive than Ferrari in a number of areas.MtthsMlw wrote: ↑Thu Sep 13, 2018 6:27 pmhttps://imgr1.auto-motor-und-sport.de/H ... 188115.jpg
Usually it's there for driver comfort more than aero performance. It changes the aerodynamic forces on the helmet and can be more or less comfortable for each driver
Mercedes do but it's not as high as that one. Each car is different so the effectiveness will be individual to each car. Just because RedBull don't do it, doesn't mean a lot.
