Dne 15/07/2017 v 11:23 Poutnik napsal(a):

If used more realistic value for the mass ratio 1 : 15 [1]
and the state of art nozzle speed 4.5 km/s
for bi-component liquid fuel.....

10% of mass is the next stage or final cargo modul.
6 % of mass is the stage construction mass.
84% of mass is the stage fuel mass. ( mas ratio 1 : 15 = 6 : 90 )

the total mass, with 3 ton final cargo modul,
( with useful mass much less )

total mass would be 3 000 ton, about the Saturn V

m0/m1 will be always the same 100/16 = cca 7.14
ln 7.14 = cca 1.97

delta_v for each stage will be 4.5 * 1.97 = cca 8.9 km/s
Total delta_v will be 3 * 8.9 = 26.7 km/s
