Hey every one,
Having one of those cold rainy boring days today, walked down to the garrage and saw my old hoverboard smashed sitting in the corner looking sad.
Then I thought I wonder if any one has tryed to make one really light weight as in insted of using wood use plastic or a pvc pipe frame and insted of a petrol powerd leafblower using a battery operated blower (prehaps overdriven hehe)
My hovercraft went ok it was verry heavy it had a habit of turning around in circles and crashing it was alright on smooth and bumpy concrete surfaces but not water, sand (wet sand however was fantastic) or even grass
Has any one had any success building some thing like this that will go over rough grass land, sand, water?
Check out this one http://www.youtube.com/watch?v=Pd1TRWynuDU this is pritty cool wish I could find some info on what he built it out of

I've seen hovercrafts done before using a lawnmower engine and a fan blade. The key is to use a ducted fan design, keping a close tolerance between the blades and the duct. Aluminum works well for a frame, then dense foam for teh rest of the body. |

It looks to me as if he just took the engine and blade off a push lawn mower. I doubt that the blade could make enough air for it, though... Maybe he put a fan blade on the shaft? I am still trying to figure out what the red part of the frame was, though. Aluminum? Fiber glass? |

Sadly, I suspect that the weight of the batteries probably add up to more then a small gas engine unless you used very advanced and expensive Lithium Ion/Lithium Polymer.
The issue with hovercrafts and control is that there is very little friction between the craft and the ground. Obviously we know this, which is why the work. To create a stable hovercraft you need a decent skirt that slightly rubs the ground. That creates enough friction.
You can also install a single caster wheel to drag on the ground, but personally I think that's lame. |
