As @doug_ellison pointed out on Twitter, the authors of the latter paper have made an old, unfortunate error. It's apparent in the first sentence of the introduction...

QUOTE
Supersonic wind-tunnel tests of 0.813 m disk-gap-band parachutes were conducted in a 10 x 10 ft cross section of
a closed-loop wind tunnel.

My gripe was the drawing of the parachute that was marked out in inches - without even, anywhere, saying 'inches'. Just '22.00 approx' on the width. Oh, and the well known ounces per square yard.

Man...If there's ONE lesson that should have been permanently learned for a reason I won't rehash in every aspect of UMSF, this is it. sad.gif

A few will take this knowledge and use this power of a dream realized as a force for change, an impetus for further discovery to make less ancient dreams real.

The 10ft x 10ft wind tunnel doesn't bother me so much - it was probably built as a 10ft x 10ft wind tunnel, like the 120ft wind tunnel at Ames - that's what it's called.

But unless it's in the form of a pseudo proper noun like that - it is utterly horrifying (as Scott suggested in marsandme a sol or so ago) that they would use these outdated units.
