• The CLV model looks to me to represent the original 4-segment 1st stage and 5.5metre dia. upper stage. If so, I assume this will need to be replaced with a wind tunnel model representative of the revised design.

  Do we know for sure that NASA is going to go with the 5 meter over the 5.5? has this moved beyond speculation and become offical?

  yes

• Another pic of the CLV wind tunnel test.  I'm not sure of the configuration, but if it is the original Design Analysis Cycle (DAC-0) configuration, then it is a 5 segment SRB, 5.5 m upper stage.

• Here is a Schlieren image at Mach 4.45, AOA 0 deg.

• Another Schlerien but at AOA 6 deg

• Judging from those photos, it looks like they will use RCS for attitude control instead of fins near the bottom.

  There will be RCS on the forward adaptor for roll control
