Abstract
This paper summarizes the development of an aerodynamic disturbance test facility that can be used to study the influence of crosswind disturbances on road vehicle handling. A literature review of ambient wind measurements and wind tunnel tests was combined with preliminary analysis to develop the requirements for a low cost, transportable, easy to operate, rugged, test facility. The final product consists of 8 independent crosswind modules, capable of providing a relatively constant 35 mph gust over 120 ft test length. Arranging the modules in an uneven fashion can provide a variable velocity profile over 230 ft test length. Each module consists of a controllable speed 58 hp gasoline engine driving an 8 ft diameter, 6 bladed propeller. Special ducting and adjustable exit vanes allow for flow redirection and expansion. Remote control of each module’s fan speed and engine ignition can be accomplished from individual remote operating stations.
