Serial staging design results (cont.)

For a one stage earth to LEO, no solution was found using Isp 301 with any value of ε from 0.08 to 2.0 broken into 20 different values.
For 2 or 3 stages, solutions where found and is shown in the next slides.
For 2 stages, total rocket mass was 69,174 kg with fuel taking 62,345 kg of that.
For 3 stages, total rocket mass was 51,078 kg with fuel taking 45,696 kg of that. We see that here adding a 3rd stage results in a saving of about 30% of fuel. Hence for earth to LEO, 3 stage solution was selected.

For a one stage earth to LEO, no solution was found using Isp 301 with any value of ε from 0.08 to 2.0 broken into 20 different values.
