Collapsible airfoils which reduce wind resistance in their operational positions on the front and rear of a vehicle are moved with minimum effort to and from collapsed stored positions on the sides of the vehicle, such as a truck. A multi-section frame is provided for each resilient airfoil section adapted to be configured flatly for storage and configured erected in use. Slide mechanisms for the folding of resilient airfoil sections are provided front and rear on the vehicle side walls. A secure locking device for the airfoils in their erected operational positions is provided.

An airfoil for lessening wind resistance of trucks and semi-trailers adapted to be bifurcated into two airfoil sections stored flatly beside the truck sides and erected into a tapered unitized configuration to the front or rear of the truck, and with each airfoil section comprising a resilient side

An airfoil for lessening wind resistance of trucks and semi-trailers adapted to be bifurcated into two airfoil sections stored flatly beside the truck sides and erected into a tapered unitized configuration to the front or rear of the truck, and with each airfoil section comprising a resilient side panel, a resilient top panel hinged to the top of said side panel, and a resilient bottom panel hinged to the bottom of said side panel, a frame for each of said airfoil sections, with each frame comprised of a plurality of frame sections coupled together and including a section attached to said side panel and other sections attached to said top and bottom panels, and with each frame adapted to be configured flatly for storage beside said side panel and erected into an erect position with said frames of each airfoil section interlocked and urging said side, top and bottom panels outwardly into a tapered, unitized configuration.
