Has any one done any research on opening size/volume and drag for bluff bodies?
If you'll go up to the Aero.Forum and do a Search Ecomodder for 'full-boat-tail trailer for T-100' you'll find some pictorial drag tables for tractor-trailer rigs which include 'gap' drag.
Also,in wind tunnel research on top-down convertibles,the wind tunnel personnel discovered that placing mannequins in the test vehicle seats positively influenced drag.
You could patent a line of Velcro-attached,break-away, clothing -fairings which would close off the transverse contamination of the body fairing void,while allowing the rider range of motion to dynamically balance the bike during crosswinds and gusts.
Better hurry to file your patent,as at least two others are currently drafting their's!
