Here is a project me and to friends have been working on, a pulse jet powered "snowmobile".
The pulse jet engine is little over 3m long and are designed to give 1500-2000N of thrust
If you are interested i can add some more picts later.

Not what I expected when I saw '12" bore full auto" in the side bar, but I can't say I'm disappointed!

Bloody hell, you Nordic people have all the fun :-/

Woke up to snow this morning. A snow plow or melter would be better than hand shoveling it.

It looks like that pulse jet has more thrust than most U Tube designs. Well done guys. I hope your valve holds up well. The reed valve designs are known for destroying valves. I noticed your intake is rectangular instead of the normal daisy reed valve design. Care to share your valve design?

Pulse jet reeds are known for quickly being damaged to this condition.

Looking for other valve styles revealed this nice design.
