I want to make an 11 foot propeller that has a 6 inch or smaller cord, 10% camber at the tip, and can handle 15 pounds of thrust. It would be an easy task, except has an almost 90 degree twist running through it.
Maybe I need to google propeller construction, but I want mine to be hollow wood. I also don't want to carve foam or use composites.
I'm planning to have a structural skin, with twisted webbing on the inside, but I think that would be weak because of the twist. I also get the feeling a half inch camber would be very weak. I could also use multiple straight tubes at different angles. I guess I'll try to find pictures of someone else's and see how they did it. Ah, the benefits of standing on the shoulders of giants.
