Truck aero cap

[t vago]

Here's another idea for a truck aerocap - very little roof/sail interaction.

And it did take some fair amount of work.

Thanks for showing. My original concept is not far off from the construction method.



I determned that I really want it to open up, hatchback style. I am finallizing the 4 bar hinge. I am also thinking it would be useful to just remove the hatchback door and allow bikes and gear to stick out however the entire cap still needs to easily remove it so I can use the back for hauling. As some would say, just polishing a turd but I actually use it as a truck. I often think I should just get a more fuel efficent vehicle but I would still need to have a truck for hauling, towing, adventuring, etc. So that means I would need 2 vehicles and I don't drive enough to justify 2 vehicles.

What would you think of a sliding panel instead of lifting the entire thing?

I think you'll like mpgs and rear downforce ( reduced rear lift ) the cap provides.
'bondo' ( member Brett Herndon ) sent me a Masters Thesis from a US Navy officer, who CFD and road-tested a cap, virtually identical to what you've come up with, on his Dodge RAM 1500.
It's already a 'known quantity.'

Imagine folding panels.

Yep, I read that thesis from a link in this here forum... I think one of your posts, in fact! That aerocap was a lot of fun to model and construct, and it served me well for many years, up until I ended up selling the truck.

Found this when I was looking for something else:

In a world worth living in,NISSAN would offer that cap as a 'performance' option, for all it's pickups, plus the mirrors.
( and discourage the lift kit , rear wing, and off-road tires! )

Found this when I was looking for something else, once again:



This could work for an aerocap.

The intent of my aero shell was to end up with a single, passenger-side opening, allowing me to reach tools and equipment from the curbside while on jobs. The canopy hinge system the I saw on the 1997 LANCAIR at Oshkosh would have worked perfectly.
Rain-guttering an weather-stripping would protect power tools and materials from Texas' blowing rain storms 'n such.
Now that my body's shot, and I'm no longer 'working, I'll most likely never do the modification.
