aerodynamics

Aerodynamics is a simple formula. CdA which is its drag coefficient times its frontal area. Both matter. My Aliner is basically a proverbial brick, so it has a poor Cd, but it has a small frontal area. In the other direction an Airstream has an excellent Cd, but a large frontal area. Most TTs are the worst of both worlds. Even those with a rounded front end have a barn door flat rear end creating lots of drag. Adding Air Tabs helps, as will a tail cone. But reducing the frontal area, like a HiLo or a Trailmanor is even better. A pop-up teardrop would be the best solution if anyone would build one.

Here's a scalable concept I drew up years ago.
