Description

This is the first stage of a ducted fan engine that i will be building

Instructions

Simply add supports and print. There is a 3.15 mm centre hole for an electric motor. I have left a 2mm hole right through in order to secure with a grub screw from both sides.

I will release all of the other parts as soon as I know that they work.

Please feel free to edit and make this thing better.

Blade are back to front. They need to be mirrored to spin in this direction or rotated so the fan spins the other direction. Why is the duct shaped like an exhaust nozzle?

Hi, I do, will try and post them over the weekend.

do you have the cad files?

Nice one mscouch

Just made one. I uploaded the photo. Came out pretty nice. Improvements could be made, but i can get quite a bit of power out of it.

Excellent!

The baldes are designed to turn clockwise as a lot of motors have skightly more power in this direction. This is the first fan that I have designed with CAD so it is all up for interpritation and new devivatives.

Is it just me or are the fan blades inverted?

Did you try to print this thing? (If not, tell you it's not an easy task to make it).

Yes, just printed it, came out well after a couple of false starts. Will post pics.
