Aerodynamic "Bogie Skirt" concepts
Aerodynamic fender-mounted Marker/Turn Signal Lamp for a truck.
Various depictions of logos and badges during the 1986 transition from the International harvester Company to Navistar. A New York consulting firm created the new logotypes and Brand Standards, but the design team had to figure out how to turn them in to 3D badges to be placed on vehicles. I was part of that team and these designs eventually evolved in to the first generation of Navistar/International era badges.

Various Design Concepts from early career

Various early design work included design concepts for truck rear-tire "Bogie Skirts" to aid in aerodynamic performance. Such skirts have never been production-ized to this day, although many concepts have been created and showed. The side skirts did however go in to production and utilized a GE engineered plastic (GTX) that was blow-molded into parts that could be trimmed to cover trucks of various wheel-base configurations. This was a first in the industry for trucks and for blow-molding and Navistar was awarded innovation accolades by the Plastic Industry. These Side-Skirts were also early predecessors to improved Aerodynamic devices seen today. I was involved in extensive wind-tunnel testing and research through-out the development cycle and have continued to foster strong relationships with my peers in Aerodynamics Engineering.

  • Luke; thanks for the interest in my work and the insightful comments. A lot of my concepts were things we tested and proved aided aerodynamics and splash and spray suppression. But, as is often the case, leadership determines if they think customers will accept the concept. Back in the 80's, fuel economy was just becoming an issue. I predict you'll see more rear tire skirts in the next decade if fuel prices continue to escalate. Which they will. Even /25 years later, rear wheel skirts are an idea ahead of their time.

  • Why were these truck designs turned down? With trucks with these side-skirts, they can have more security on the rear wheels.
