Tom, in light of our discussions, I went back to the drawing board and applied the principles we had discussed - up to a point. I took the S410...
Tom, returning to the problem of 95 kPa being too much structurally for a 12% foil: I’ll explore this in more detail when time permits. I’ll note...
Thanks Tom for your as usual perspicuous observations. What Tom is saying makes perfect sense when loadings and pitch are constant, or...
One final point re leading edge sensitivity: Although I don't know of objective measures other than the behaviours exhibited in the analysis...
Thanks Erwan. I’m not the best person to ask to compare XFLR5 and XFOIL. I haven’t worked with XFOIL. If the analysis would benefit I’d look at...
I have designed the S410 foil in XFLR5 with the intention of using it as a lifting T foil in the Re 2m to 5m range on the 16.8m proa I'm building....
Like Phil said, symmetrical foils develop lift with angle of attack. In addition, foil shape will typically target low drag in the neutral...
Is this due to the sharp leading edge or the fact that the rudder section was highly cambered? I have my concerns re sharp leading edges for...
This approach to rotating the board is changing. A new rudder mechanism has been developed by Etamax: http://etamax.com.au/ The concept can be...
5 foil comparison In this post, I've compared 5 foils in order to explain my thoughts on leading edge shape and camber. Tom Speer has...
As far as foil configurations go, I've consider many for the windward hull. I referred to an option I'm strongly considering in an earlier post:...
I'm keen to see you get this working. I'm particularly interested in these symmetrical Tom Speer inspired foils for my proa. Stienar's and the...
This would indeed be the case if the lee hull flew as with SailRocket. Given the lateral resistance of the slender lee hull, the foil kite forces...
In this analysis I'm comparing a thin, fine entry, Speer inspired foil with the Eppler 817. Reynold's number is a bit high for small craft at 4m....
