General Layout Characteristics and Performance of a New Wind Tunnel for Aerodynamic and Functional Tests on Full-Scale Vehicles

This paper discusses the advantages of closed type and open type working sections of a wind tunnel designed for aerodynamic tests on full-scale vehicles. Analyses of economic considerations, component efficiency, and applicability to the specific purpose of testing were the deciding factors in choosing the open type working section for this wind tunnel being erected by Pininfarina at Torino, Italy. Preliminary design work and supporting research are described.
