Hi Guys
This is my first post. I hope someone can help. I'm building a hovercraft, the fan that lifts the hovercraft is made of pine timber and the blades are carved from the pine. The blades weigh 200grams each and are spinning at 3000rpm. Question, if a blade broke of wilst spinning at 3000rpm, how thick should I make a duct or shrould (from alumimium) to keep the blade from breaking though and hurting anyone? Many thanks Colin De Bruyn
