Maybe the tank is just not a large hollow structure but contains fins/compartments/whatever to restrict the sloshing motion and it's not that big a contribution

Maybe the tank is just not a large hollow structure but contains fins/compartments/whatever to restrict the sloshing motion and it's not that big a contribution to the overall motion.
If it's no stronger than a sudden wind gust, it's just something the controller has to be able to take care of without a heads-up.
- TowerTall 2y agoThat is how they build the tank in Formula One Racing (and probably many other race cars, I guess)
- kaonwarb 2y agoThese are indeed part of the solution and are known as baffles. They have risks of their own, e.g.: https://wccftech.com/baffling-baffles-musk-explains-why-spacexs-mars-rocket-prototype-exploded/amp/ https://wccftech.com/baffling-baffles-musk-explains-why-spac...
- nuancebydefault 2y agoIn the first spacex rocket Musk thought that it was a good idea to not install baffles. He learned from experience that they are indeed needed.
- m4rtink 2y agoI remember a very similar anecdote about Von Braun & the early Juno/Jupiter rockets - with someone pointing out issues with sloshing on a press conference & Von Braun brushing it off as insignificant. Then the next launch crashed due to slosh induced oscillation - and the one rocket after that had anti-slosh baffles. ;-)
- vocram 2y agoThat’s how tanks in race cars are made. Another solution is fill the tank with some kind of sponge-like material.
