Hello
I've seen the marvelous creation of hovercrafts by Paul Kleniewski (
http://www.brickshelf.com/cgi-bin/gallery.cgi?f=32403 ) and that gave me
some ideas.
Here can you see a simpel construction of an propell that I made. I've not
taken any photos yet, but here is one image made in Ldraw:

The only diffrence by this and my construction of the propeller is that I've
used the Technic Panel Fairing #20 (or #21 depending of the direction of
rotation) instead of #3 /#4. They are a lot smoother and push more air.
I've made an small hovercraft with the same principle as Paul's hovercraft
but I only used a 9v battery pack to drive the old style 9v motor. And I got
lift! :)
Is the tunnel around the propell very important?
Does it makes the propell push more air?
There are probably some leaks of air around my construction. But I think the
prop can be turned about as fast as you want because no parts will deatach
when spinning in high speed.

| Some hoover crafts use a tunnel/prop design facing backwards and direct about 1/3-rd of the air downwards to create lift, the rest is used to push the craft forward (with rudders to steer). Perhaps this can be made with LEGO? The main benefit is (...) (21 years ago, 6-Feb-03, to lugnet.technic)
