Hello to all! Yer friendly newbie again...
Even though I'm looking for more of a backroad crawler instead of an interstate cruiser, I've been looking online at what the big rigs do to control air turbulence on their trucks and load. Found several good links that may help folks who have long-distance cruisers and are skilled enough to fabricate their own parts.
For underbelly air turbulence
I thought this was very interesting. Someone covered smoothing out the undercarriage of the bus briefly in another thread. One of this comany's videos features an interview where the guy explains the version is the 7th design mod and that they're constantly tweaking it for better performance.
For general air turbulence
Now THIS product is really quite cool. It's versetile enough to be used all over a vehicle, regardless of conviguration. Instead of filling gaps between a big rig cab and the trailer, it smooths the turbulence enough to redirect the air away from the gap. Also shown on vehicles that range from a box truck to an already aerodynamic camper. This can help anyone.
Front and rear
Very "bubbles" that redirect air flow. These can be seen everywhere - even on regular cargo trailers.
Just good information from folks doing the research.
Skirting & rear wind deflectors for DIY
This site has some good images that may give folks that are handy with fabrication ideas for personal projects.
General aerodynamic information from DOT
More general information.
I know a lot of this folks may already have seen, but I figure there are still plenty of us out there in the planning stages that every little bit helps.
