VEHICLE STREAMLINING DEVICE FOR PRESSURE DRAG REDUCTION

摘要

A simple, low-cost, truncated (22), aerodynamic, inflatable (24) afterbody (20) reduces vehicle pressure drag significantly. It has one or more ram air cells (26) opening towards the direction of movement (24). Its asymmetrical shape enhances the stability and increases effectiveness of the afterbody (20). Fuel use, pollution caused by fuel waste turbulence are all reduced.
