FlowBelow Aero devices control air flow and boost economy by 3%, says Indian River Transport.
September 9, 2015
Stainless steel tanker trailers look smooth enough to easily slip through the air, but they have characteristics that cause drag. One fleet has turned to an aero system for the tractor tandems to help smooth the air flow over the trailer.

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.
