Computational fluid analysis interpreted air flow over the trailer panels’ surfaces, finding some drag produced by rivet heads.
August 26, 2015
Lord Corp., which makes bonding adhesives, has done research that indicates eliminating rivets from a trailer’s walls might cut aerodynamic drag by about 1%.

Trucks, on the road or on flatcars, are often part of model railroads, as Senior Editor Tom Berg found at the Toy Train Museum.

An arrow-shaped aero device diverts wind away from the tandem, while a covering of the frame rails and crossmembers reduces turbulence there.
April 28, 2015
Unlike most skirts that are stationary, the stinger moves with the tandem as it’s slid fore and aft, so it smooths air flow no matter where the tandem is set, said the system’s inventor.
