Roof Spoiler on Pick-Up Truck Cab - Phase-1

[kach22i]

Oh, I like that Toyota pick-up truck.

Before Photobucket screwed us all I posted something/sketches similar. Similar if they tapered it in plan that is.

That car is new to me.

Air brakes?

Pale Moon won't accept the Photobucket-fix extension so I can't look through some old threads, but wasn't there one where someone cut up a fiberglass canopy to make a partial aerocap? Before moving on to a full aerocap?

kach22i — I like the Slow Moving Vehicle signs, but (per US regulation) they should have the tips cut off

Sounds familiar, fb

Aerohead this car has the aero features running down the C piller I was speeking of .

Close up of the" C piller Turning Vains "

Notice the Duck Butt (1sided kam back) mother Gaia installed at the back. Also pay attention to how she fixed the antenna mount , and solved the puzzle on the most effective patch for recessed glass/rain gutters.. some of the things I notice

Better view of the Duck Butt . It appears that gravity took its turn in the creative process when/as the wind died down. Causing the abnormally tight curve like a duck tucking tail. With out the up wash coming around the bumper(lower recirculation bubble) with enough force to support the tail feathers they fell.

If Gaia had only softened the side-to-top edges,it would be vortex free!
Hey,did you get a USFRA 'Participant' T-shirt after your assault on the salt with Jona?

[gumby79]

Yes

That's a very instructive set of pictures.

I'm looking for a similarity to T-150 C-pillar 'turning vanes' in vain. Maybe it's because of the open suicide half-door. When I think of flying butter-arses, it's the modern Ford GT40, the VW Golf GTI650-W12 or, for pickups, the Yamaha Cross Hub

Back to the pictures: 'Cowl induction' hood, the rooftop vortexes start at the windshield (!), the flattening of the flow aft of the gully between the rear fender flare and fence formed by the side trim, The snowballs on the wheels, the effect of the rear view mirrors. On and on.... Icicles on the tail-lights?

I've been reading about aircrete. It is Portland cement mixed with a 200:1 mixture of water and Dawn dishwashing soap, and a bubble size around 10 microns. One could bury a car in a mound of the stuff (a stiff mixture, with a touch of white glue) parked behind a tubojet like the ones they use to blow out oilwell fires.

A sacriifcial body to make a male mold? But the stuff floats on water, maybe hollow it out with an air tool and paint it?

In the video below is a gate spoiler and cab attachment similar to some of my sketches and ponderings of the past.

Dang, he even used a sidestep/sportstep.

My sketches did have it going more to a half-round.

EDIT

I love the use of an extra long string over the top of the truck at around the 4:00 mark.
