Mercedes F1 chief technical officer James Allison is confident that his technical team has found the root cause of the German-Anglo squad’s recent gearbox failures and can make the necessary changes to avoid its reappearance.
If what is said in the car dimension thread is true: viewtopic.php?f=12&t=25999popovic94 wrote:Some crazy assumption here, is it posible that Mercedes didnt want to change wining combination of W07 and because of rules that changed width of car they just used "scalle" on W08 and thats how they got longer wheelbase, yes they got a lot of new winglets and stuff but basic shape is same. Flow structure should be the same on car that is scaled 1, 0.8 or 0.5 if i understand corectly, because of that wind tunnel testing is always with model that is scale version of real car.
You are probably right, i didnt run the numbers, this was like I said just crazy assumption while i was thinking why have they done that3jawchuck wrote:If what is said in the car dimension thread is true: viewtopic.php?f=12&t=25999popovic94 wrote:Some crazy assumption here, is it posible that Mercedes didnt want to change wining combination of W07 and because of rules that changed width of car they just used "scalle" on W08 and thats how they got longer wheelbase, yes they got a lot of new winglets and stuff but basic shape is same.

Then the wheelbase increased by 7% but the overall width increased by 11%. Although, even if the percentages matched they most certainly did not just scale the car up!
For this to be true you would need to match at least Reynolds numbers in wind tunnel and on track. This roughly means you can compare data for 60% model with the car going on track at 60% of the speed from wind tunnel (to keep it simple). Your idea isn't bad at all, after you dominate like no one has for 3 years with one design you wouldn't want to radically change everything and risk biting more than you can chew. Right?! However, with aero changes as extensive as they are in 2017 your assumption probably isn't 100% correct.popovic94 wrote:Flow structure should be the same on car that is scaled 1, 0.8 or 0.5 if i understand corectly, because of that wind tunnel testing is always with model that is scale version of real car.
There definitely seem to be some big changes in airflow around barge boards and in front of sidepod inlets, even on Mercedes.

Honestly, no idea. When they did aero rake runs, they took these horns off so they can't be some silver bullet. But that's not how Mercedes does things, isn't it?PlatinumZealot wrote:At the horns below. I can see a little red sensor poking out of the slit.
It makes me wonder if the slits was just a quick way to poke the sensor through or if they were designed for more a sinister reason like intenionally weaking the structure allowing the horn to bend.
My best guess is that those slots are some vortex generators, if not just simple slots for easier sensor placement. As for weakening the structure, I doubt it, that's not the place to do it to make them move up or down (or any other way I think)... Then how about "reflection" on the second photo where the red point in that place is visible?PhillipM wrote:The more I look at the picture zoomed in the more I think it's just a reflection on a machining mark from the same red light that's reflecting down the front of the strake and bargeboards.
It's not high enough resolution for me to see tbh, although I concede there's a single red pixel there, but there isn't on the photo above. I'll have a look back through the other pictures.Yurasyk wrote: Then how about "reflection" on the second photo where the red point in that place is visible?
I thought that those slots are there to be compliant with the "looking at the floor from bottom" rule. It should cover everything and the floor has slits at those places.Vanja #66 wrote:Honestly, no idea. When they did aero rake runs, they took these horns off so they can't be some silver bullet.
