hydrofoil parts maker or for sail?

I m looking for hydrofoils less the Boat .for 9m vessel . Dues any One know where there made or is the a set I can buy 2nd hand .

This could be an interesting thread. I was once thinking of using discarded helecopter rotors apparantly they are about the right NACA in alluminium.

How big and what kind of boat do you want to lift.

 

What a Great idea ! a launch (composite/glass)for day trips , to Islands and coastal runs . a beam on 2m max swell

 

Well don't just run off and do it, we want to know what happens, how you did it and some pics too.

Apparantly the firm that manufactures them wants the old ones back to destroy, but I got a deal that the operating lugs would be cut off and I could take the rotor blade only (fine with me). The guy died before I got one.

The chord is about 1 foot which I think would be perfect.

 

A cordless reciprocating saw on a moonless night could yield you a life time supply of foil shapes.

 

I have a feeling Par has his tounge in his cheek.

 

sound s good to . but material and cross section shape ? You would nt have that in put ?

 

Depends on what chopper you have as a donar.

I did all this some time ago and now forgotten but the rotor I was getting was surprisingly the NACA I wanted.

 

Which rotor was that ? I regularly travel by chopper. Where could I find a cross section Plan?

 

Find out what chopper it is then google it

I was "going" to get a blade of a Sikorsky. Sorry about spelling

Then google NACA design. You quite a bit to go have'nt you?

here is an example of the differences it is by all means not all of them --there is thousands.

 

thanks for that . I always saw the similarity s between air and water shapes

 

Hydrofoils

=========================
Dr. Sam Bradfield( hydrofoil pioneer) and his company Hydrosail offer aluminum and carbon fiber hydrofoils for different loadings as well as hydrofoil engineering services-contact them for more information( premade foils for boats 16' - 40') :

John Ilett of Perth Australia is a custom hydrofoil builder with engineering capabilities as well. He built some excellent custom wood and carbon fiber foils for me(see pix below) : http://www.fastacraft.com/

Good luck-I'd like to hear more about your application at your convenience.
