Specifically, the mass after the burn, M b , is the sum of the payload mass, M PL , plus the dry (empty) weight of the whole propulsion system, M Dry , which is in turn made up of the weight of tanks, engines, pumps, structure, etc. In trying to get the maximum delivered payload mass M PL (or ratio of M PL /M 0 ), the choice of best propulsion system is complicated by the fact that high I sp propulsion systems generally have a larger dry mass than low-I sp systems, so the choice is not...
