<p>A vehicle streamliner has a balloon or bag member that is supported by a belt member that is tensioned about a generally cylindrical longitudinal perimeter surface of the vehicle. The bag member can be configured for support against an end face area of the vehicle, and preferred shapes for the bag member are disclosed. An array of vortex generators are provided proximate a forward extremity of the belt member for promoting attached flow ahead of and over the bag member. A pair of the belt members can connect the bag member between tandem articulated vehicle elements for smoothly covering a gap between the elements, the bag member being formed of a thin, stretchable material that assumes a pleated condition when relaxed, the pleats disappearing when the vehicle elements are proximately aligned.</p> |
