Automatic rear airfoil for vehicle

摘要

A twin bag inflatable rear airfoil for truck or transport trailer with attached shelves that bridge the surface gap between the trailer side and top surfaces, and the corresponding side and top surfaces of the inflatable bags. Shelves also bridge the upper surface gap between the two bags and provide a platform to deploy a collapsible yaw control fin. Another set of panels provide airfoil surfaces in the ground domain and are integral to the organised automatic folding and stowage of the apparatus. Interrupted ribs stiffen the inflatable surfaces while allowing them to fold in an orderly manner.
