In recent years increasing interest has been shown in the saving of energy used for the operation of various types of land transport vehicles. This is especially true for vehicles travelling at high speeds since power consumed to overcome aerodynamic drag rises proportionately with the cube of the relative air velocity over a vehicle. In order to study the aerodynamics of vehicles, especially the aspect of aerodynamic drag, a basic research project entitled Aerodynamics of Road and Rail Vehicles was launched. The paper deals with some practical aspects of the research work done under the project heading, most of the work being investigations carried out in wind tunnels.
