1. An apparatus for decreasing aerodynamic drag, improving stability, and decreasing road spray of a transport vehicle, comprising:
an underbody fairing for mounting to a bottom portion of a transport trailer forward of the rear wheel assembly, said underbody fairing comprising a substantially parabolic elongated panel having a first edge portion, a second edge portion, a first lateral portion and a second lateral portion, and a vertex portion, said vertex portion being substantially arcuate; wherein the shortest distance between (i) the intersection of said vertex portion with said first lateral portion and (ii) the intersection of said vertex portion with said second lateral portion is between twenty percent and fifty percent of the shortest distance between (i) said first edge portion and (ii) said second edge portion; whereby said underbody fairing diverts airflow around the rear wheel assembly of the transport vehicle while facilitating the laminar flow of crosswind beneath the transport vehicle, thereby decreasing aerodynamic drag, improving stability, and decreasing road spray of the transport vehicle. |
