Resumen
DU BUISSON, J. J. y ERENS, P. J.. Reduction of Aerodynamic Resistance of Heavy Vehicles and Effect on Fuel Economy. R&D j. (Matieland, Online) [online]. 1990, vol.6, pp.26-31. ISSN 2309-8988.
A number of commercially available aerodynamic drag reducing devices have been evaluated for different angles of incidence using wind tunnel model tests. The information gained has been incorporated into a computer program simulating the operating conditions of a typical tractor and trailer combination. The program includes statistical information on wind strength and direction as well as terrain conditions for a typical long distance haul on South African roads as well as engine performance and gear ratio data. In this way it was possible to make realistic assessments of the various configurations for reduction of aerodynamic drag with a view to possible fuel savings.
