Trike transformation

Next study is to test what would it mean to transform this object into three wheel concept. Model is transformed into trike with 2 front wheels and study calculates the drag change. Ther's two pictures, first shows the pressure map and the second shows the velocity map. Velocity plot is a planar cut from a certain distance above the ground where the turbulence caused by the front wheel is highly visible.





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.
