Using BurnTimeCalc MFD, what exactly am I looking at with the Estimate Total dV number? While sitting on the ground with a full load of fuel, why is this number so low? (XR-2, full fuel load, the Estimate Total dV shows less than 7.000 km/s) Thanks.
That's a bit much. 4.5km/s is more typical.It seems that to get to orbit I'll need around 9.3-10 km/s..
