I understand what's happening now, finally. The pivot point for polar analyzing is probably fixed at x=25, y=0. So when it increases the angle of...
My "Copy (text)" and "Paste (text)" buttons were greyed out. Find and open in a text editor "java.policy" - mine (win 10) was in "Program Files...
Thanks. Anyway, in this case it's not the X, it's the Y offsetting that screws up Cm 0.25. The following file is the same foil (NACA 0020) at Y=0,...
And how would you retract it underway? Not saying it can't be done, but I don't think they intend to. Dropping it for every tack maybe? Or do they...
Maybe it can. I believe the main idea with the L foil is that when the vertical part comes more out of the water, the boat skids more to leeward....
The L foils are mostly just a way to get around the ban against flaps and active incidence control.
I don't think there are any efficient and fast boats that use a spinaker. Boats that sail up to several times the windspeed always sail into the...
Why?
I think those are the driveshaft supports you are referring to as rudders on Miss Britain III - I suppose the better analogy is fins. So what...
1. Stability and balance Ah, I mixed up the terms. I think I meant to say: Can not the traditional requirement for a lighter loaded tail, to...
Tansl, yes that diagram shows what I ment. "Another question, why do America's Cup boats in 2017 adopt negative trim when they fly?" They can't...
From the numbers in the presentation, the rear foils carry 72%.
Maybe this boat is helping your argument... It's made to crab to leeward... [ATTACH]
Since all (?) submerged T foilers are fly by wire anyway (referring to the wand sensors etc), is it still important to maintain pitch balance for...
[ATTACH] I'm probably explaining myself poorly. How can I translate a Cm that is taken from 25, 0 to a different X, Y coordinate?
If you hung a turbine from a plank off the gunwale. If it was a Darrieus, or a normal propeller with pitch reversal, it could turn the same way...
No indeed CT, there will be lift. But won't it be difficult to create a hull shape that is a good low drag (sideways) lifting shape at 18-30...
It would be nice indeed to have computers take control of the boat in commercial sailships, otherwise it's going to be much more expensive to run...
Hi mass... I think all the power graphs (3 from TANSL, one from Ad Hoc and one from me) that models your hull is trying to do the same - predict...
I really want to be able to do a 'flying shunt' one day. #flying tack #proa
