What should I use for a hovercraft fan? Answered
I have all the necessary building materials (wood, plastic tarp, foam, etc...) as well as a 22 hp engine and a weed whacker engine (both gasoline). I'm having trouble figuring out what i need in terms of a lifting fan. I've determined that i need something that can provide at least 4000cfm. I've looked at industrial shop fans 20+ inches in diameter which seem to provide enough airflow to work, but I've never seen them used in my research. Can anyone help?
