DIY carbon fiber hydrofoil

Postby Hawaiis » Sun Oct 27, 2013 11:58 pm

I bought this 4mm flat sheet of carbon fiber, cut it into shape and round off the edges and drill three holes and Voila, a carbon fiber foil.

You mentioned "The Titanium front wings were tested first without anhedral, they were very unstable",
so than how are you going to make this stable with this flat out peace :?:

Does this carbon foil, which looks to be a lower aspect ratio than the titanium foil, offer more stability without the need for anhedrals?

What flavor of carbon fiber?
Which way are the fibers aligned?
What thickness is the plate?
Dimensions compared to carafino or titanium samples?

Yes, low AR wings does not need anhedral as much as high AR wings.
The wooden low AR wing has no anhedral, and was working fine.
I will eventually put on winglets to test the difference.

The 4mm thickness is only 1/2 of the factory Carafino wing it replaces.
The carbon plate looks like a 2K twill 90 degree vacuum bagged.
The size is 16"X8"

But does the Carafino wing have an airfoil ?

The Carafino weigh how much compared to yours ?

Carafino looks like a piece of art with G10 fiberglass sheet CNC 4-12mm covered with Carbon fiber.
The shape looked more like a curved flat sheet with rounded edges than a NACA foil shape.
weight :950g vs 450g

Carafino = 950g
Yours ---- = 450g
and there approximately the same aria, but Carafino's is Twice as Thick ?

And thanks for weighing them : Bille

Will this work,, or is it too thick? I was planning to do that a while ago, but than I changed my mind when I saw how thin the factory build fuselages are.
