PROCESS AND WIND-TUNNEL SCALES FOR AERODYNAMIC MEASUREMENTS ON VEHICLES

摘要

The feature of the process of the invention for finding the forces and moments affecting a vehicle on its passage through a fluid (relative wind) is that the fan moment Mlü or the fan power Plü derived therefrom and to be included which is generated by the fan effect of a wheel rim (17) is also detected. It is thus possible to reach close correspondence between wind-tunnel tests and actual road tests. The process of the invention is preferably applied with 24-components scales and "bridges" or 6-component scales.
