The Chrysler 3/8-Scale Pilot Wind Tunnel

The Chrysler 3/8-scale model automotive wind tunnel is a pilot facility for a planned full-size tunnel of the same design. The 3/8-scale tunnel, which has a complete compliment of instrumentation including a pressure system and high-precision balance, will also be used for 3/8 model aerodynamic development testing of vehicles after piloting is complete. The tunnel is convertible from a slotted-wall test section to a semi-open jet test section. Commissioning, calibration, and piloting results show the performance of some features being piloted including slotted-wall effectiveness, open jet collector performance, and tunnel background noise levels. Calibration results include static and dynamic pressure distributions.
