A METHOD OF DECREASING THE DRAG OF A HEAVY-DUTY TRUCK WITH THE USE OF FRONT AND STERN BOARD GENERATORS OF LARGE-SCALE VORTICES

A method of improvement of the aerodynamic and working characteristics of automobiles with the use of generators of large-scale vortices is proposed. The drag of a model container truck, on which board vortex generators were positioned in front of the cab of the truck and at the rear of its container, was experimentally investigated. By varying the geometric parameters of the model truck, its rational arrangement providing a decrease in the drag of the truck and an economy of the fuel consumed by it was determined.
