Abstract

The high speed yaw stability of a car - trailer combination is affected by the vertical load at the hitch point. This parameter can be influenced by the aerodynamic pitching moment of the trailer. In this paper various scale model trailers and additional aerodynamic devices are investigated in a 7′ by 5′ high speed wind tunnel. The aerodynamic pitching characteristics are assessed over a range of sideslip conditions and conclusions are drawn about their influence upon the system stability. It is argued that the high speed yaw stability of towed trailers can be reduced by 14% due to aerodynamic effects.
