The Body Engineer's Role in Automotive Aerodynamics 640051
Aerodynamic streamlining is assuming greater importance with our sustained driving speeds on new expressways. Benefits of streamlining include reduced wind noise, reduced lift and better stability, improved acceleration at passing speeds, higher cruising and top speeds, better fuel economy, and reduced initial costs.
Basic principles of aerodynamics for automobiles are presented. Application of these principles are discussed and depicted for different types of automobiles and a tractor-trailer unit. Tables, formulas, and examples are included. Trends show aerodynamics as a factor of increasing importance for the automobile. It is suggested that a joint training program be initiated for body engineers and aerodynamicists with classroom studies based on detail design problems.
