Line 1: Line 1:
The current best-estimates for the dimensions of various test articles is here, along with the relevant experimental parameters and reported forces.  Note that complete dimensions are not known in most cases, and some had to be determined via indirect methods (e.g., estimation from photographs).

All known and estimated device parameters and results have been moved to [[Experimental Results]].
 
 
Credit to Dr. Rodal and others for the great effort in [http://forum.nasaspaceflight.com/index.php?topic=36313.msg1376840#msg1376840 compiling these].  Please note some caveats for this data, at that link.
