Why the NASA Turned This SEMI-TRUCK into a BAR OF SOAP | History

Specifically, we are talking about the AERODYNAMIC PRINCIPLES that proved how CABOVER TRUCKS, which completely dominated highway transport during the middle of the last century, were ridiculously inefficient. This only became a major problem when the OIL CRISIS forced the industry to look for better alternatives. Interestingly, this entire research and its later applications started with a bicycle incident. EDWIN J. SALTZMAN unintentionally experienced firsthand the brutal wind effects caused by the boxy, unoptimized shapes of 1970s trucks. While CABOVER TRUCKS represent a tiny fraction of the market today, NASA’S DISCOVERIES have become key building blocks for MODERN TRUCK DESIGN.
