Yes,APEX is kinda Dark Ages design.There is a sloping and upper radiused nose in elevation,but zero edge radii in plan view.
The deflector has a bit of curvature to the sides and it was thought that some of the source flow could be directed laterally,allowing APEX' nose to ride within it's wake.
Rough without a wind tunnel and no time to do a tuft test.Sucks!
1,200 miles of data will help us appraise it's value.
Bob,sure like the PV/deflector! Two birds,one stone!
