Let me rephrase: I think they reworked the shape of the undercut, which, seen from above, looks like the upper surface of an airfoil, to displace the lowest pressure area and put it more backwards. And thanks to the overcut, that low pressure area will pull air from the top surface of the sidepod more effectively and direct it in the coke bottle area.Blackout wrote: ↑Sat Mar 14, 2020 11:34 amRenault opted for RB-inspired sidepods/engine cover for 2020, like RP during the 2019 season, https://pbs.twimg.com/media/EAU_fpIWsAA ... ame=medium an engine cover that merges the top airflow and the side air flow more upstream of the diffuser...
And that's how the "RB" sidepods work... Am I right?
They sweep the widest part of the undercut backward to make the air that accelerates around it suck the top air
That's also the case here (racing point) https://pbs.twimg.com/media/EAU_fpIWsAA ... ame=medium
So the RS.19 undercut shape looked like the ULM upper surface and it's pressure distribution looked thoroughly like this
While the RS.20 undercut shape looks more like that propeller blade upper surface and the lowest pressure area would look more like this
