photos
I'll try for images.Forget it!
I do this so little I can't remember from one time to another and if I don't bring the proper 25-pound work with me I leave home without instructions.
I managed to get the images into photo-bucket but I don't remember how to link them to here.
The store will be closed in a little while,I'll try again Monday,Sorry!

From photobucket, if you copy the IMG code which will be beside or below the picture somewhere, then if you paste that here it should work.

I remember getting on the image and sliding down to the IMG code and clicking.I'll try a right click. |

Clicking it should highlight it, might even automatically copy it, I don't remember exactly. But either way, when it is highlighted, copy it, and paste that code here as if it were text and that should do it. Sorry for the late reply.

Phil: I added 2 of the images from your Photobucket album to post #1 in this thread.
Clever design, by the way.
Also added a link in your "signature" to your photo albums (Photobucket & your albums here on EcoModder). (That won't show up until you post again.) Maybe others here can help out when you get stuck, since they'll have the album links.

I did locate my other work-book which had my instructions for Photo-bucket,'n maybe I can function a bit better.
Having access to the Photo-bucket album is really good though,as members can just browse around in there and see if anything strikes them.
Tanks again big-time!

3D
This rig (SUV w/ deflector + Apex trailer) may be an instructive example.
From Hucho's compendium.
The Apex already has a generous roof edge radius in profile (side) view. In plan (top) view it has pretty sharp edges. Gilkison reported to Phil record high mileage. To my brain all this evidence supports sidewall splash as a likely problem that the rooftop deflector addressed.
It would be nice to see 3D streamlines from proper CFD, or tufted sides of the trailer with and without the deflector, to further demonstrate benefit. I suspect long term FE will show real gain. With real world variability, however, scientific confidence requires more trips, patience for us, and generosity of those involved to share.
Rock on! |

leading edges will be next
In plan view APEX' corners have zero radius.
I've been collecting large radii structures to use as molds for wet layups.
An awning company could also roll square aluminum tubing and heli-arc it into an Airstream-esque birdcage framework onto which tailored awning fabric could be attached forming a very light,hollow nose cavity add-on.
Awnings stand up to Texas thunderstorms all the time.I see no reason why they wouldn't do fine on the face of a trailer.
Anyway,when time avails itself,I'll get into this one.
We're also going to do a fairing for the rooftop AC unit as orbywan has done.

Huge help, KB!! I've had a hard time with deflectors as the RV world is one in which the desire for better mpg is a constant question. The lack of good record keeping is one hindrance, the annual miles another (for comparison purposes). And more are the differences between rigs (TV & TT).
So about a 4.6% mpg increase on this trip.
Which is in the neighborhood of a 9% drag reduction (wind averaged).
Am looking forward to more as it is available.
