Planing Wheels

PlaningWheels

A lifting and propulsion device for amphibious use; consisting of a wheel like device with angled planing surfaces arranged around the circumference of the wheel such that when operating in water and the wheel is rotated the planing surfaces provide a lifting force directed downwards and a propulsive force directed rearwards thereby raising the associated watercraft above the surface of the water and simultaneously propelling it forward. When on land this device operates more or less like a conventional drive wheel on a land vehicle.

 

There are several variations of that system. For example, search snowmobiles over water.

 

You had this on here several years ago, have you tried it yet? Do the front end wheels get powered also? Reverse looks to be problematic, as does steering.

 

God I hate that noise! Stop them before they spread! Pretty cool tech, though......but still- throw a net over that guy!

 

yeah its cool but it can not get popular! lol ))

 

The model is 4 feet long - 4 wheel drive - 6 hp - 24 lb.
What works best is a relatively large contact area with a good aspect ratio. Hopefully you end up with a high lift to drag ratio that increases with speed.
Fast Track Amphibian is an example of the snowmobile approach however it pushes more water sideways than straight back and is mechanically complicated and inefficient.

 

Have you tried it yet?

 

Looking at the amount of parts and the possibility of getting snagged with debris in your design, a snowmobile seems much simpler. Also, those paddles will vibrate the fillings off your teeth on land.

 

I see the possibility of too much turbulence to even get a bite (back wheels) at high speeds anyway.

 

Something simple maybe be good in the snow as well.

 

That won't work. The paddles need to be tilted the opposite way to get any traction.

 

I give up

 

Why?

 

If you read my first post the paddles push the water downwards and rearwards. Resulting in a 45 deg. thrust vector pointing downwards and rearwards.
