Serial staging with single rocket engine design (cont)

Engines selected: For upper stages (LEO to GEO). For stage1 use IUS SRM-1 from Boeing, a Solid rocket motor with a thrust of 185.1 KN and Isp 295.5 secs. For stage 2 use IUS SRM-2 with thrust 78.41 KN and ISP 289.1 sec.
For final GEO maneuvering use rocket engine RL10B-2 from Pratt&Whitney, an LO1/H2 liquid engine with a thrust of 111 KN and Isp 462.
For earth to LEO: Use Titan4 first stage LR-87-AJ-11 Nitrogen engine with Isp 301. For second and third stage use Titan4 LR-91-AJ-11 with Isp 316.
Make a list of the above engines. Run the MATLAB design program to design the rocket for one or two or three stages. Look at the output and decide how many stages to use based on the cost benefit of adding additional stages for the fuel saving gained.
