My point in asking was to see the achievable Cd's of something this large - OD about 27' IIRC. I'm not asking for the overall Cd of the 4 piece complex, just calculated values for the main tank alone.
Anyone know why the main tank has a rounded bottom .vs. cone? My guess was the added mass and difficulty flowing the H2 into the shuttle overwhelmed the potential lower drag.

The Shuttle is heavy enough that aerodynamics (apart from wings potentially falling off at max Q) aren't really so relevant. Big rockets are a big win in most respects unfortunately. >> _______________________________________________ ERPS-list mailing list [EMAIL PROTECTED] http://lists.erps.org/mailman/listinfo/erps-list
