Is a Trinity Trailer more or less aerodynamic than a conventional square sided competitor’s trailer?

trinity-trailer-group-shotIn order to provide the answer once and for all, Trinity employed the services of a major U.S. mechanical and aerospace engineering service provider. This company utilized sophisticated CFD (Computational Fluid Dynamics) tools to analyze the Trinity EagleBridge belt trailer design compared to other traditional belt trailers. In all cases the Trinity trailer performed as well or better in direct comparisons.

Three simulations were performed;

  1. Tractor and Trailer combination at 65 mph, no crosswind.
  2. Trailer only at 65 mph, no crosswind.
  3. Tractor and Trailer at 65 mph with a 15° crosswind.

In our model comparison; being pulled by a tractor with a full wind fairing over the cab, no significant differences in aerodynamic properties were measured. In this 65 mph test it was determined that the major factor in wind resistance is the type of tractor unit and the aerodynamic properties of the tractor.

In the second and third simulations, the trailer only and tractor-trailer combination with a crosswind, the Trinity unit had proven to have significantly less wind resistance. This resulted from the aerodynamic shape of the Trinity trailer as opposed to a square structure of a competitor’s trailer being forced through the air. It was also analyzed and conclusively determined that the exoskeleton of the Trinity trailer has little to no effect on the overall aerodynamics of the unit, and the narrower frontal and side profiles of the Trinity trailer prove by extensive computer modeling and simulation to have less wind resistance than a traditional square sided trailer design.

So what does all that really mean? Trinity trailers have less wind resistance than a traditional trailer. And that translates to direct cost savings for you.
