REDUCTION OF AERODYNAMIC DRAG OF LARGE HIGHWAY TRUCKS
The Program involved field and road testing of single chassis truck units and tractor/trailer combinations to test and demonstrate simple, legal, practical devices which would would reduce aerodynamic drag. Deceleration, hill rolling, fuel flow, and fuel consumption tests were conducted. A number of devices were tested and their performance determined. A simple new lip-type device was developed which gave 23 percent fuel savings at 57 mph, on unloaded single chassis units. The very significant adverse effects of crosswinds on aerodynamic drag and on test precision were demonstrated. /Author/
