      Abbreviated rules   07/28/2017

      Underdawg did an excellent job of explaining the rules.  Here's the simplified version: Don't insinuate Pedo.  Warning and or timeout for a first offense.  PermaFlick for any subsequent offenses Don't out members.  See above for penalties.  Caveat:  if you have ever used your own real name or personal information here on the forums since, like, ever - it doesn't count and you are fair game. If you see spam posts, report it to the mods.  We do not hang out in every thread 24/7 If you see any of the above, report it to the mods by hitting the Report button in the offending post.   We do not take action for foul language, off-subject content, or abusive behavior unless it escalates to persistent stalking.  There may be times that we might warn someone or flick someone for something particularly egregious.  There is no standard, we will know it when we see it.  If you continually report things that do not fall into rules #1 or 2 above, you may very well get a timeout yourself for annoying the Mods with repeated whining.  Use your best judgement. Warnings, timeouts, suspensions and flicks are arbitrary and capricious.  Deal with it.  Welcome to anarchy.   If you are a newbie, there are unwritten rules to adhere to.  They will be explained to you soon enough.

  1. Can't see any mention of accumulator capacity there. But what I'm curious about is how much of a tack or gibe fully charged accumulators can power. I've seen no data anywhere to permit that calculation, do you have any? edit...Or even what capacity they'd have to be to allow the completion of one manoeuvre. You'd need to know the sizes of the hydraulic actuators (cylinders & motors) before anyone can make any meaningful calculations, and I doubt they'd make that info available because their opposition can make the same calculations and determine their power generation capacities. Yes totally depends what your actuators are and how you are using your accumulators. By rules, 1 is dedicated to foils and rudders but only in pitch and 2 others are dedicated to foil extension. Now those accumulators are One Design with a dry volume of 4.5L Obviously to be a useful accumulator they need to be pre-charged with gaz at a certain pressure which induces the Energy you will be able to store in it from that pre-charge to 350 bars that is the limit of Max Rule Pressure. Depending of your pre-charge, the available oil volume varies too. Each team can choose the pre-charge of each accumulator. For instance, @ 120 bars precharge and assuming an accumulator charged to Max pressure, you will store about 1.5L in oil which translates into about 30KJ in Stored Energy. But again it is to each team to be smart enough on how to use it and this is a good part of the Energy strategy which will be a hidden part but important of the next AC. So Indio is right no one is going to tell you more... I believe you will store 3.0l of oil if the accumulator total volume is constant (and is not isolated): gas volume at 350bar is 350/120*4.5l=1.5l so 4.5-1.5=3.0l of oil has to enter the accumulator. Which translate into 60kJ according to https://en.wikipedia.org/wiki/Isothermal_process#Calculation_of_work. If you consider 4 grinders producing 300W each that's 50seconds of grinding to recharge. You probably should get something similar for the non grinding time if you discharge the accumulator.
