And the results, overall force of drag is in Newtons
single wheel(two wheel version) 1.3N
dual front wheel trike 3.5N
Differencies are significant, and probably this is not the best trike designs to think of.
Separating front wheels 40% more away from the body only increased the overall drag to 3.7N. But moving wheels closer to the nose decreased the drag dramatically. Final overall drag is now only 2.5N with object that looks like this.

Is it better to have the front two wheels inside the fairing for better aerodynamics? I was thinking a very narrow streamliner like the Varna with external front wheels would be the best way to go. Happy Trails, Todd
