The swept fins from the Nike Fin pdf may just be drawn goofy to exaggerate the single-wedgeness.

It is hard to see but the real swept fins look as if they may have a double-wedge to them???
But if the pdf version of the fins looks better when drawn properly I would bet that these are in fact the same fins that we are looking for (apologies to Obi)

Do you have the document that the link is for?

I have the PDF version of that document, downloaded form the link I posted.

I get the "403" error.

Chris,

I just got that, too . . . Apparently, the link was time-limited.

This will take you to a full copy of the PDF.

Looking closely at the TIF files, the fins do appear to have a double wedge airfoil.

Is it real or an effect of lighting ? Not sure.

Turns out I had that same report downloaded years ago.
A simple NASA doc search with TM-X-1152 works.
That one and a bunch of other wind tunnel models dealing with the Trailblazer's fin choices.
Too much data and not enough unpaid interns to organize my filing system!
Thanks Dave.

Anytime, sir !

Chris,

Do you happen to have any data for the SUPER CHIEF II ?

I am, specifically, looking for data on the Interstage and the "surface details" of the Payload Section.

I have contacted John Brohm, without success.

Thanks !
