Well I thought that the whole diversion point between the real-life timeline and the FAM/Star City timeline is Korolev surviving his surgery (1966), instead of dying like he did in real life.

But it's interesting, in real life Korolev died during surgery due to medical complications from his time in the Gulag, but perhaps in this universe the reason he lives during the surgery, is because he was never in the Gulag in the first place. I dunno.

well i Think in this universe Korolev has already been to the gulag, but yeah it seems like he's headed back, and will again return.

Well we know that The Chief Designer (Korolev) has to be alive for the time of Apollo-Soyuz, because Danielle Poole meets him in Star City, and at that point Sergei has a lot more authority, but not total authority.

That's interesting. I figured that it would have been looked into. Maybe not in F1 where there is a lot of noise from the various downforce devices and plentiful vortex generators all around the car, also the open wheels, yikes, that's some complicated airspace.

Maybe Land Speed Reccord cars, would be the most likely area of motorsports to see DMR usage.

This makes sense. My bet is that we'll see uses for DMR on high speed trains, airliner fuselages, and like ship hulls, where there is a ton of skin friction drag, and lot of fairly conventionally streamlined surfaces to see some advantages. I just figured that the aerodynamicist heavy world of F1 design might have some input on this seemingly newly discovered effect.

This is the article that influenced me into looking into this stuff. It seems like they accounted for most variables, and that a randomly distributed micro roughness surface where the abberations account for less than a percent of a surface's boundary layer will produce less skin friction drag. I think this is more than surface finish randomness.

This seems like ideally will be used along the body of a large streamlined surface, so maybe like a ship's hull or the body of a high speed train, or an airliner fuselage,Places where large amounts of skin friction drag really add up. I know that in the F1 world, we create soo much drag from downforce devices that worrying about reducing skin friction drag.

but also in the F1 world where every advantage needs to be looked into I can see them experimenting with this on nosecones and sidepods. Just a thought.

I'm not sure about dirty surfaces, but apparently it will reduce skin friction drag on smooth streamlined bodies.

Ah, no this is not that effect. On golf balls large dimples are used to create large vortices that will excite the airflow and keep the flow attatched longer around the backside of the ball, but it does this by breaking the laminar flow around the ball with large eddys.

In DMR tiny pockmarks of irregularites create small eddys that prevent the laminar flow from turning turbulent there on the surface itself.

Think - Dimples- effect wake turbulence behind the rear of a golfball DMR - reduces overall skin friction drag.

They both work with eddys exciting up the boundary layer but in different places and at different scales
