Inert mass fraction
Web1 mrt. 2024 · The RLL inert mass, m R L L, would be, (1c) m R L L = f m · m w where f m is RLL inert mass fraction, and m w is the mass of a full RLL. We fix m w at 45 t, the nominal SLS capability to the cislunar aggregation point. WebYou can calculate that mass from the answer though, which turns out to be 183 kg. So if 183 kg of the 3000 kg dry mass is discarded after the kick and before the auxiliary maneuvers, then you can get the 7390 kg of total propellant. – Mark Adler Sep 5, 2015 at 20:33 Though that would be a 3.4% dry mass fraction, which is unreasonably low.
