More insight was extracted last night from this study... the above image
indicates
how the air enters the cockpit after the door has departed; at the lower rear
frame rail... it then whips around at the centerline toward the front for
the uppercut rearward exit; this creates a vortex in the lower luggage well, and
another in the front footwell to head area.
Several deflectors were tested at 100kt.. upper forward rail visor, side forward
visor, a lower side rail board, and rear lower rail louvre... all additions
performed some affect with the louvre setup providing the best outcome toward
reducing cockpit turbulence to a pleasant level while doorless.
