Residency Evil posted:Can a smart F1 engineer (that definitely posts in this thread) explain to me why/how both RB cars died within a lap of each other? My guess is as good as yours. Something overheating and failing at roughly the same time maybe? I wouldn't worry about your engineer friend, we get paid whatever happens.

Dante posted:Considering Russel is the only mercedes engine starting in the first ten places I wonder what the chances are that every single mercedes supplied team has crippling aero issues, and that there's no correlation with the power unit being the common denominator. You're saying either/or but tbh it's probably both.

MustardFacial posted:Rebus, if you had good correlation between CFD data and wind tunnel data, could you design and build functional aero surfaces just from CFD without testing them in the wind tunnel at all? Or is wind tunnel time a requirement for getting parts on a car? Are there things that only wind tunnel time can show? (Navier-Stokes turbulence data aside, of course) In theory the bare minimum you need to do to get a part on the car is: 1. Check it's legal. 2. Check it's not going to break when stressed at representative conditions. I've known parts to go on a car which haven't been tunnel tested but in general everything has been through CFD, mostly because it's practically zero effort to send your geometry off to be simulated. It's important to understand that CFD gives a tremendous amount of data about one very specific condition, so it's used to answer very specific questions: "does my funky shaped winglet do the job of pushing this bit of dirty air away from that part of bodywork, which we've observed to cause loss of downforce in high speed corners with high rear ride height?" And the purpose of the WT test is to check the overall performance: "does my funky shaped winglet correlate with what I saw in CFD, and does it also not have any negative effects elsewhere in the envelope of where we expect the car to be, and does it function as a whole with all the other bits we've since changed?" There are some transient and hysteresis effects that are difficult to replicate in CFD, but they're also difficult to replicate in the tunnel (I don't recall anyone saying they saw porpoising on their tunnel models). All of it needs to be taken with a pinch of salt and as a scientific experiment with a degree of error.

tuo posted:Out of interest: how much do vibrations from the engine and heat buildup influence such a scenario? The wind tunnel models are still smaller, correct? Like 1:2 or something like that? Or are they full size nowadays, and could theoretically house a running engine? Are the wind tunnel models the same weight (in regard to scale) than the real thing, with similar weight distribution? Tunnel models are 60% scale. Sophistication of model systems vary by team, but they all have internals that simulate exhaust blowing. Weight and weight distribution are kind of not a thing - we are interested in the forces exerted on the model by the airflow so it's more important that it's geometrically correct rather than physically correct. We do try and make the tyre shape as close to the track condition as possible through various clever methods.

tuo posted:Especially in regard to the porpoising, wouldn't a simulation of the suspension help to detect something like that before the car hits the track/testing? Or is the suspension actually not relevant towards this effect, and it is purely aerodynamics? It's likely all relevant! ArmZ posted:is this why porpoising seemed like a surprise or was that just the media latching onto something

tuo posted:Thanks a lot for the feedback! Full size models would help hugely with correlation, but would also increase costs and put teams at a disadvantage who do not have access to a tunnel capable of fitting one. The general noises from the FIA have been moving toward banning use of wind tunnels entirely, so I doubt they'd lift or relax any of the current restrictions before then.

Tbh it's not as complicated as you'd think. There's a technical document somewhere that tells you how you should calculate your spent allowance.

If you look in appendix 8 section 4 in the sporting regs you'll find the calculation for CFD usage. Bit of light reading for an evening.

ethanol posted:so is it safe to assume a team uses up all this comp time before the season even starts? is more time allotted over the course of a season, or this just like, given in bulk for any given year The year is split into periods of about 8 weeks - the limits are apportioned across the year into these periods, and are also now influenced by championship position (perform good get less WT and CFD allowance, perform poo poo and get more). It's "use it or lose it" so if you aren't up against the limit at the end of the period then you can't carry it over, and if you use it all well in advance of the end of the period then you have a lot of aeros sat doing nothing.

Thanks Ants posted:Let Rebus be race director That's v kind of you but I'm not v qualified for that. I'd like to recommend "fan director" which crowdsources all decisions based from a slider in the F1 app that goes between "I like what I'm seeing", "that chap looks in peril, bring out the safety car", and "let's spice this poo poo up I'm bored". Some other quick time events could be added to keep everyone engaged.

italian quid posted:Rebus why aren't you sponsored by Ponos anymore. I love that loving dumb cat mobile gatcha game. Hadn't even noticed they'd gone. I guess it silently expired. Thanks Ants posted:What did Rokit do? I suspect even the worst sponsor of five years ago was more legit than crypto. They're still sponsoring in other series I think? I'm still thankful to rokit, not for their terrible phones which I had to endure for a year, but their rokit drinks sub-brand which introduced me to ABK beer.

Yeah we got a 4 pack of special edition beer with a picture of Frank (famous teetotaler) on the label. I could manage with the screen, but the audio quality was like everyone was underwater. Also they overheated and crashed daily.

Thanks Ants posted:Afaik you can’t do anything during the break, no wind tunnel stuff, no manufacturing etc. There are a few exceptions, things like maintenance of the manufacturing equipment, wind tunnel, and IT hardware that would be difficult to schedule in otherwise. Other than that, anyone who doesn't directly contribute to making the car go faster doesn't get shutdown.

Literally everyone else is off too so there's no distractions at all and I don't feel any need to be within 10 minutes of a laptop at all times. Mostly looking forward to Spa as I've got hospitality tickets to watch the race at the HQ conference centre.
