2024 and no tubercle hydrofoil wings? Seems like there are performance advantages that could be utilized. Wondering if current design tools, analysis tools or manufacturing processes don’t support the shaping? Additional production costs? Marketing risks too high? Or maybe prototype testing identifi...
if so easy, why a professional does need help ? Because he knows it’s easy till something goes wrong and it can go wrong, to bad really fast. Also agree landing can be challenging too, best to get an assistance if possible. Whenever getting assistance handling a foil kite best to explain clearly ho...
Using examples or Peterlynn arc or speed3 19m is out of date today. Agreed. My 17m Cloud1 LEI and 13m Peak4 SS are also things of the past and no good for twin tipin freestyle. We are just killing time here with nonsense waiting to see if a new freestyle 20+m LEI comes to fruition. Meanwhile, how a...
…After realizing that 10m Rally 2012 (sized as 9m Rally of following model years) is more powerful and quicker than 10m Speed4 (pre-Lotus), after realizing the same about 17m Core XR2LW on 39m lines vs 19m Speed3 Deluxe…there was just no way back. I remember doing a similar double/long line test wi...
Just linking to it as example charts of how Lift, Drag, L/D (“upwind”) correlates to camber. He was asking about an airfoil, this example is for hydro, but hopefully it helps present the concepts.
Depending the airfoil shape: is a foil with more camber supposed to have better upwind? I never understood this, doesn’t a flatter foil have less drag than a bent one?
