Is 50 Miles Per Gallon Possible With Correct Streamlining? 330041

THIS is Part 2 of a study of air resistance in terms that the automobile engineer can understand without delving deeply into aerodynamics. In Part 1, after analyzing car resistance mathematically, the author related how air resistance was determined by wind-tunnel tests of various body models and presented tabulated and charted results. A study of the test methods used is presented herewith, together with comparisons made between the results obtained in Part 1 and those obtained in Part 2 from road tests of a car equipped with a so-called “floating envelope.”
Fuel consumption is considered also, since full advantage of streamlining cannot be obtained without improvement of the transmission to provide for sufficient activity of a car at the lower speeds.
In conclusion, the salient facts of the entire paper are summarized and seven specific suggestions for streamlining are made to car builders.
