I'm considering building a twin tip hydroifoil that could be used in kiteboarding. that means it needs to be efficient in both direction (like a...
A couple of questions... - What is a classical value of neutral angle of attack for both foils on a moth (I mean at zero deg. boat attitude)...
okay, but using xfoil, you can only get the Cl and cd with one flap angle, for many general angle of attack... I would like to get the opposite !...
flap?? Hi guys, Does anybody know what law should be used to calculate the lift and drag of a foil when the flap angle changes. I mean a...
Okay sorry for that I just went through the bladerider instruction manual, and I saw that the attachement (to the flap) is 90 degrees away from...
I would also appreciate your opinion about Teflon Waxed surfaces, because this is what was really making a big difference during the good old...
Let's be very clear. To me the only problem with an incidence controlled main foil is that the variatiopn would be very large during the flight...
just to explain further what I thought. The current wand uses the Cosinus part of the wand motion, whose variation becomes larger as the wand...
This is what I thought, the coef are just what you decide to make out of them, but I didn't know what was the common calculation on Xfoil....
Wooow, at last I did it. I just finished reading the 574 posts, and that was definitely worth it. Better than any book, as somebody said long...
