AbstractThrough its ecoTECHNOLOGY for Vehicles program, Transport Canada commissioned the National Research Council Canada (NRC) to investigate the aerodynamic improvements possible with current and emerging drag reduction technologies for heavy-duty vehicles, with the intent of guiding future implementation and regulation of such technologies for Canada’s transportation industry. A wind-tunnel test campaign was undertaken in the NRC 9 m Wind Tunnel to evaluate the aerodynamic performance of various drag reduction concepts, with an emphasis on those for trailers, using a 30% scale model of modern tractor-trailer combinations. Project stakeholders also include Environment Canada’s Transportation Division.
