Is 50 Miles Per Gallon Possible With Correct Streamlining? 330039

THIS is Part 1 of a study of air resistance in terms that the automobile engineer can understand without delving deeply into aerodynamics. The study was suggested by the fact that motor-vehicles are now being driven at a speed at which most of the engine power is used to overcome air resistance, although the greater part of this resistance is unnecessary and can be eliminated by correct shaping of the vehicle body. It is a progress report of research just begun.
After analyzing car resistance mathematically, the author relates how air resistance was determined by wind-tunnel tests of various body models. Numerous illustrations are utilized to portray the models and the testing equipment, and the data obtained are tabulated and charted.
