Sounds like a heat-exchanger design might fit well with a circular ring of chambers around a large blunt base plug - make that the heat-exchange surface during ascent (could it also be an LH2-cooled heat shield for descent??), and then control flow to the chambers for attitude control. -dave w _______________________________________________ ERPS-list mailing list [EMAIL PROTECTED] http://lists.erps.org/mailman/listinfo/erps-list
