Conventional vs Beam Wiper Blades aerodynamic?

[airbiteses]

Which wipers have less air resistance while driving? flat or skeleton? Because one car had skeleton wipers at the factory and it is possible to have flat or hybrid ones.

[Piotrsko]

Because they are messing with boundary layer flow, it isn't just one design over the other. Could also be down in the data noise area also and would be difficult to see much change

Most wipers are in the low pressure zone behind the air intake where the hood and windshield meat do they don’t have any affect on the aero. I even removed my wipers. Made no difference in testing

More economy to be had by long-lived blades in operation?

I think most missed the point, the aero wipers offered main attribute is to add contact pressure at speed enhancing their effectiveness in redirecting water off the windshield. Other purchaser misconceptions about positives are likely left to stand unaddressed by the manufacturers as good marketing for the g/dullible. The Aero positive effect of whatever it is, is also likely only during a very limited amount of the wipers arc in use.

Actually, I believe it is thought to be a high pressure, low velocity zone?

Depends on the vehicle architecture. Lamborghini Countach/Cypertruck have no discernable cowl. The Cybertruck stores the wiper longitudinally.

Years back, ROAD & TRACK wrote that in a road test of one of the Lamborghinis, that before they hit the 205-mph top speed, the wipers had already completely lifted off of the windshield, straining against their preload tensioning springs.
And in the 1970s, Porsche added inverted, cambered 'wing' deflectors to their wipers, presumably to address the same issue.

That problem is of little concern to me, as I tend to stay under 200mph in the rain , and seldom take my Lambo out in it.

Seriously, we should be looking to aircraft wipers for inspiration on this topic.

Tesla got the folks who built the wipers for the Space Shuttle to design the Cybertruck's unit.
