I am designing a trailer, probably shaped like a teardrop, and I am looking for information on optimal design. I have not found much in the way of specific information, so any info is appreciated. How does relate to the slope coefficient of drag? Is there a specific equation that can determine the coefficient trail of a slope? I guess the front of the trailer must be steeper than the rear … As I said, all the advice you can offer is appreciated =)

In incompressible flow, it is unfortunately not an equation that gives you Nice Cd being equal both the sin of the angle of the thing-something. The good news is, there are enough user friendly programs that you can connect the points your trailer (wing) and out lift and drag, etc. Sub2D is free because the organization is not more but I may be hard to find. Try DesignFoil or Profili but perhaps a small investment. Manually connect to points is a tedious task to keep your cursor over the image of your trailer 2D image Microsoft Paint and contact information unless they can import more advanced. Better yet, find a friend with a CFD program ask them to please run your trailer through it.
