ABSTRACT:
An air drag reduction unit for reducing air drag caused by the upper surface, corners and edges of a vehicle such as a truck or trailer. The air drag reduction unit is an inflatable shell that is mounted onto the upper surface of the vehicle. The shell includes a flat rigid sheet surrounded by a flexible curtain. When the vehicle achieves a predetermined speed, the shell inflates due to the Bernoulli effect. The inflated shell has rounded corners and a flat upper surface several inches above the upper surface of the vehicle, thereby reducing drag. When the vehicle slows below the predetermined speed, the shell deflates. Due to the elastic nature of the shell, the shell contracts onto the upper surface of the vehicle, thereby not substantially adding to the dimensions of the vehicle when deflated.
