A technique is described which allows the aerodynamic characteristics of the cross wind gusts that are commonly experienced by passenger vehicles to be correctly represented in wind tunnels. This characterization includes the modelling of wind strength and direction, gust duration and the cross wind boundary layer. The technique uses conventional wind tunnel model and instrumentation configurations and relies upon a second nozzle and shutter arrangement to give complete control over the profile and duration of the cross wind gust. Data from some initial proving tests are presented to demonstrate the potential of the method.
