Basicly a typical truck looks like this.
Most of the bed covers that people look into making look like this, or aren't even tapered at the end.
What I am thinking looks more like this. With the tail gate down there would be a lot less trailing edge.
Or with the "fins" tapered down. Obviously the fin tapers would have to be clear for the tail lights.
Is there a reason for not doing this? The reasons I can think of are:
- The amount of volume is reduced.
- There may be additional turbulence created by the "fins".
- The angle may be too steep depending on truck
Are there others that I'm just not thinking of? I know Phil Knox didn't do this, so I figure there must be a reason. I don't have a truck to do this on, but I suggested it to my dad and he said it would be too much hassle to get in and out, so he wanted nothing to do with it... but I thought maybe someone else would. |
Rising this thread back from the dead, because I missed it originally, and another site had a link to this thread
Arerodynamics - MJ Tech - Comanche Club Forums
( It's nice to see a truck forum not bad mouthing EM and taking it serious
)
So I too have thought of that fourth design, ( haven't we all ) and I was wondering if the question was ever answered, regarding what makes the 'finned' version an inferior design. ( never-mind the angle of the aero shell - I'm just talking about the sides of the truck that become the 'fins' of this design. )
I'm guessing there would be no benefit because you would still get the spill over that results in a vortex. The air in that area is moving upward to where the tail-lights are and spilling over,
not going straight back like we think it would.
