Design program algorithm. Serial staging
LEO to GEO:
try one stage. Use Isp=295.5, ε list. Solve for mp and Z using the optimization algorithm for one stage by trying for each value of ε list.
try 2 stages. Use Isp=[295.5 289.1] , ε list. Solve for mp and Z using optimization algorithm for two stages.
try 3 stages. Use Isp=[295.5 289.1 289.1 ] , ε list. Solve for mp and Z using optimization algorithm for three stages.
Ask: How much reduction in total mp we obtained from going from one stage to 2 stages? Is reduction worthwhile? (> 5-10% ?) If so, then ask the same question for going from 2 stages to 3 stages. Based on this, select the number of stages to use.
