Brock Racing Aerovault trailer
I saw an ad for this in Grassroots Motorsports magazine. The one in the ad and in the brochure even has moon hubcaps. The underside is skinned!!

It's a beautiful car hauler. SInce you will never park it up to a loading dock why not go all the way and make a hinged boattail for it. He doesn't seem to address the turbulence coming off that square rear end, which contributes most of the drag.
Otherwise a bit pricey @ $17,000 but a step in the right direction. |
I think the added length is an even bigger problem with a trailer like this than a semi

It's good looking but would go better backwards.

The roof even slopes UP towards the rear of the trailer. ( Actually increasing the size of the wake .) I wonder how long it will take before everyone realizes that a wedge is not a good aerodynamic shape. |
If it was going backwards, the air would slam into the door like a brick wall, and fan out. Just because the optimal shape for a given length is a teardrop doesn't mean everything that tapers from front to rear is good. A forward wedge is better than a backward wedge any day of the week.
It's shaped the way it is to fit cars which have a low front. The back has to be big enough to fit whatever fits in the rest of the trailer, because that's where the entrance is. If it was tapered to the rear, why not just build the whole thing at that height? |
It was designed to appeal to the masses that don't know better.
Reminds me of a huuuuge arguement on some forum about whether the v-nose trailers were more aero than the flat ones. Man, it didn't matter HOW much proof you brought to the table, people had their ideas and they stuck to them like glue. :rolleyes: |
