CRX HF reverse trike project

[AndrzejM]

There is a flow image at the bottom I working on
never can get the flow 2 program to work only 1 so if any one can do one Would help.

I think you have to lower the back of the trike. The angle is too steep.

See attached picture.

I've used Flow Illustrator.

But even retaining the 4-wheel layout I would not disconsider to adapt 2 independent Unit Pro-Link setups for the rear wheels to increase the cargo volume.

Or taper the back sides together alot.

I hope your body line isn't following the roll cage because that angle is way too steep.

If you haven't heard of the aero template, here is an example of how the template should be placed.


This shape would provide minimum drag which would maximize fuel economy

A good rule of thumb is to not exceed 15 degrees taper. On the bottom you might do 10 to be safe, although with a skinny rear and single wheel you'll have to fair it to get any meaningful flow patterns back there.

Definitely go to the Template sticky in the Aerodynamics forum and throw the template over it. Jim has a very good example there; use the same technique.

I think you mentioned getting rid of the sharp corners on the rear. You need those to help flow detach smoothly.

Cool project. have you considered doing something smaller, like a 500cc or even a 250? The car shouldn't need more than like 15hp to cruise at 60mph.

excuse my ignorance, but this is something I've never understood. How can a trike be stable? it seems like the car would just tip over. Is there a secret to this? After I complete the Aerofocus I would like to start building my own car as you are doing here and a trike would really be nice, but I feel like it would just fall over.

Yes thought about is but that would be later Two giant vortecs lol
