Systems and methods for reducing aerodynamic drag on cargo trucks

Abstract

An aerodynamic drag system is provided. The aerodynamic drag system is configured to reduce air drag on a cargo truck. The aerodynamic drag system includes an air capture system, an air channel system, and an air distribution system. The air capture system is configured to capture air at a front location of a cargo truck. The air channel system is coupled with the air capture system and is configured to guide the captured air from the front location of a cargo truck to a rear location of the cargo truck. The air distribution system is coupled with the air channel system and configured to distribute the captured air at the rear of the cargo truck such that the differential pressure on the cargo truck when moving is reduced.

1 . (canceled) 
     
     
         2 . An aerodynamic drag system for reducing air drag on a cargo truck, comprising:
 a tractor tail coupled with a rear face of the cargo truck,
 wherein the rear face is located at a rear end of the cargo truck; 
 wherein the tractor tail comprises foldable doors that overlie the rear face when folded in and create a tapered tail that extends from the rear face of the cargo truck and is configured with an angle of taper relative to a top and bottom of the cargo truck; 
 wherein the tapered tail includes an inside tail chamber that allows air to flow from a front end of the tractor tail to a rear end of the tractor tail; and 
 wherein the tractor tail, when extended, creates a vacuum during operation from air flowing over the tractor tail; 
   an air capture system configured to force air from the front end of the tractor tail to a rear end of the tractor tail; and   an air distribution system coupled with the air capture system and configured to receive air from the front end of the tractor tail and distribute the forced air out of a back end of the inside tail chamber and reduces the vacuum that is created from air flowing over the tractor tail.   
     
     
         3 . The aerodynamic drag system of  claim 2 , wherein the angle of taper is relative to the top and bottom of the cargo truck and is between approximately seven degrees and twenty degrees.
