Winglets = problems

bart_v_a

Hi, so I've started designing a hydrofoil for a testing rig. Basically real world testing to see how much lift, drag, etc. it generates. However since im not familiar with making winglets I just cannot figure it out. I'm using a profile, but for some reason it wont make it into one part after enclosing the winglet.

1. Winglets how to make them work
2. Connecting the winglets

Here's a version of the 'Winglet'. I have given the top a thickness in order to make a solid otherwise the end of the winglet is infinitely thin and won't boolean

You might need some more guides to get a smoother transition.

a winglet should be the same as a wing.you might need to split it up and use more guide curves to get the correct thickness and transition. The tip of the winglet should be an airfoil with a seperate tip that lofts to point. If that makes sense ...

@michael_stalls geometry dash bloodbath Choosing the right-wing profile is crucial for the performance of your hydrofoil. Consider using airfoil profiles specifically designed for hydrofoil applications. Common profiles such as NACA (National Advisory Committee for Aeronautics) airfoils or Eppler airfoils are widely used in hydrofoil design.

Good idea
