ABSTRACT:
Apparatus for streamlining a tractor-trailer truckcomprises an inflatable balloon bag member at an end of the trailer. Supporting attachments for the bag automatically lock when the bag member is inflated but may be easily disconnected once the bag is deflated. The attachments are hinged for loading door clearance, a top attachment being hinged forwardly of the end for swinging the deflated bag to one side of the trailer. A belt timber reenforces the bag between the attachments, the bag being otherwise self-supporting. Both front and rear bag members cooperate to significantly reduce aerodynamic drag and fuel consumption on long hauls.
