DEVELOPMENT AND CALIBRATION OF AN AERODYNAMIC DISTURBANCE TEST FACILITY. VOLUME I: EXECUTIVE SUMMARY; VOLUME II: DEVELOPMENT OF REQUIREMENTS AND PRELIMINARY DESIGN; VOLUME III: CONSTRUCTION, CALIBRATION AND OPERATION
This report 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, wind tunnel tests, and accident data were combined with driving simulator tests and closed loop 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 130 ft test length. Arranging the modules in a semi-random 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' 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 located up to 200' from the facility.
