Overcoming the ‘gap’: A big obstacle still remains in truck-trailer aerodynamics

Any vehicle moving at highway speeds faces the impediments of drag, which is created in two ways. One is when anything – rearview mirrors and bug screens, for example – impedes the smooth flow of air ...

Filling the holes on the highway: Bottom-line boosting aerodynamics

Aerodynamic characteristics around the fifth wheel and the trailer’s rear are difficult to manage. The trailer gap is a necessary open space that allows for full articulation as the rig maneuvers in ...

Electric wind takes truck aerodynamics from brick to slick

Researchers at Sweden's KTH Royal Institute of Technology are developing a device that increases the fuel efficiency of trucks by cloaking them in electric wind. Using plasma actuators to charge the ...
