Devices to reduce the aerodynamic lift of road vehicles were examined in wind tunnel model tests. Front-end devices investigated ranged from forward projecting shapes to simple flat-plate air dams, together with changes to rear-end shape. The effect of an air dam on response to crosswind gusts was investigated. Model tests also examined methods of reducing overturning moments on large vehicles. The test program included measurement of aerodynamic forces and pressures, and also the use of an oil-film to show surface airflow patterns.
