Summary:

The paper refers to a research program which is presently in progress at Pininfarina. It deals with a new ground effect simulation system for full-scale car testing in an automotive wind tunnel.This research program is carried out in the framework of the "Progetto Finalizzato Trasporti 2" of the Italian C.N.R.The first part of the paper makes an analysis of:The second part of the paper describes the new Ground Effect Simulation System (GESS) which is presently in operation in the wind tunnel of the Pininfarina Aerodynamic and Aeroacoustic Research Center.Its layout is quite different from the ground effect simulation systems existing in other full-scale automotive wind tunnels. It includes several subsystems, that is to say:The new Pininfarina GESS is therefore more complex than the existing systems, however, it gives several advantages, in particular:The third part of the paper reports some preliminary results measured on a full-scale car in various conditions with fixed ground/fixed wheels, rotating wheels only, moving ground only and moving ground/rotating wheels.Although these values are likely to be "car-dependent", they give a first indication of the possible differences which can be expected when using the new Ground Effect Simulation System
