Aerodynamic curtain assembly for a tank trailer

An aerodynamic curtain assembly for a tank trailer comprising:

• a first side assembly supported adjacent a first side of a tank trailer;
• and
• a second side assembly supported adjacent a second side of the tank trailer;
• wherein the first side assembly and the second side assembly each includes:
• an upper support member extending longitudinally along one of the first side and the second side of the tank trailer,
• a lower support member extending longitudinally along the first side of the tank trailer below the upper support member,
• a flexible side air deflector screen including an upper end and a lower end,
• an upper coupler securing the upper end of the flexible side air deflector screen to the upper support member,
• a lower coupler securing the lower end of the flexible side air deflector screen to the lower support member, and
• a tail support coupled to the first side assembly and the second side assembly, the tail support including a first tail frame and a second tail frame laterally spaced apart from the first tail frame, the first tail frame supporting a rear end of the flexible side air deflector of the first side assembly, and the second tail frame supporting a rear end of the flexible side air deflector of the second side assembly.

A tank trailer comprising:

• a frame extending longitudinally between a front end and a rear end;
• a tank supported by the frame, the tank including a first side and a second side;
• a plurality of valves supported by the frame below the tank;
• an inlet supported proximate the front end of the frame;
• and
• an aerodynamic curtain assembly including:
• a front nose assembly including a front support coupled to the tank trailer, and a flexible front air deflector screen coupled to the support and extending arcuately from a first upright supported by a first side of the tank trailer to a second upright supported by a second side of the tank trailer, the inlet positioned intermediate the front nose assembly and the tank;
• a first side assembly supported adjacent the first side of the tank trailer;
• and
• a second side assembly supported adjacent the second side of the tank trailer;
• wherein the first side assembly and the second side assembly each includes:
• a longitudinally extending upper support member, and a longitudinally extending lower support member positioned below the upper support member,
• a flexible side air deflector screen including an upper end and a lower end,
• an upper coupler securing the upper end of the flexible side air deflector screen to the upper support member, and
• a lower coupler securing the lower end of the flexible side air deflector screen to the lower support member.
