I need a better way to break wind!
« on: May 22, 2010, 09:26:20 AM »
Looking for a good quick easy (and CHEAP) way to turn that HUGE flat area above the cab of my F450 truck into something a GOOD bit more aerodynamic!

The white area measures 36 inches tall by 81 inches wide. The aluminum around the corners goes out about another 5-6 inches flat before it really starts to turn backwards along the sides.

Might be moving soon (VERY likely) and likely looking at a LONG trip so anything to help with the fuel mileage would be a big bonus.

Whatever I come up with will need to be cheaper to make than the fuel it will save me or its kinda a mute point.

I got a couple ideas now. But looking for some fresh e-y-e-s and input on it. Then I will state what I think I might try (ideas I have had) and see what yah all think of them if a better idea does not come up!

I have been looking for a Aerodynamic dome off a larger trailer but not having any real luck finding one...

I am also looking (just missed a killer deal :[ ) for a lil bus that will pull my 34 foot trailer. The bus will hold as much as my truck and once out at "other dunes" I can make the Bus into a mini RV/Toter-home. Most of the buses are kinda sloped in the front so that would help there too!

But if I do not find a Bus and sell this truck I would like to try to make it aerodynamic on that near sheet of plywood I am pushing dead thru the wind! 

So how would YOU build a cheap light bubble dome and secure it??

Thanx in advance for any input!   mm:

Super Bubble bubble gum?

If it's for a one time use just frame it up with light guage tubing with about a 45* slope and cover it with thin plywood.

Something like that has crossed my mind (The tubing and plywood (not the bubble gum!) But I am TRYING to go a little more bubble shaped (rounded) than to pointed. But nothings set in stone yet.
 
I also have to try to think of too much plywood in one direction would create one hell of a load in force from the air pushing on it.

I would like to push most of it over the box. But too much being pushed up would be one hell of a load being pushed down.

I also do not want to push to much air down where it will catch the air trying to go up and over the cab perhaps.

I am also not against making the device longer and running two support tubes running down to the front bumper area if I had too. Be a nice "visor" against the sun! 

(Heck at one point I was considering making it big enough to sleep in!)

After thinking about what Fabr said and my last post I thought this pic should help as the front on pic its hard to see where the top of the box is.

Know what a hip roof is? If so just do that on the front of the box.

Sort of like this

Didn't know it by name. Googled it and I have seen a lot of them of course.

Might have merit. Not sure of the weight I could make it and have it survive buffeting 70 mph winds and road shocks though.

1/2 inch tube and 3/8 CD plywood and you're good to go. Won't add over 75#'s at most

Even if I just build a bubble or a thing like this I am wondering about air coming in (green arrows) dealing with air build-up (yellow ball) 


Something like the bottom pic has crossed my mind (and like I mentioned above if it was big enough and strang a person could lay down in it but thats reaching) The yellow lines would be support bars.

But I still wonder if this would not trap a lot of air coming straight at the windshield?

IF it were my truck, I'd take the top corner off the box.  Might have to spend a little on rounded corners (don't know what they cost), but in the long run that seems like the best solution to me.  I don't know how long you plan on keeping the truck, or how often you plan to take the highway either.

Go get 2 large beach balls and about 10 rolls of duct tape. Secure the inflated balls in the center of the space about 2' apart. Use tape to form a skin over them to the body of the truck. Saw this done in a wind tunnel...........
 
You don't want something wedge shaped, you need something rounded.

Plan to keep the truck till it dies or I find a better thing like a small toter-home or a bus I can convert.

I would prefer to keep the inside space as large as possible and just kinda add on to the outside given a choice.

Something very similair to this has been toyed with in the corners of my mind.

But for some strange reason I never thought of Duct tape! But the mention of that with my other idea might be the ticket!

Anyone else got any ideeee-eers? Gonna give it a lil more time till later to post a couple I have that are cheap and light. But may have flaws I am missing.
