Feasibility Study of Superconducting LSM Launcher System for Practical H-II Rocket
A practical feasibility study on superconducting linear synchronous motor (LSM) rocket launcher system for H-II rocket is presented on a basis of dynamic simulations of electric power energy, efficiency and power factor as well as ascending motions of the launcher and rocket. To decrease vastly maximum reactive power per section and to improve electrical efficiency and power factor, fourpower- supply (A-B-C-D) system is introduced to shorten one section length as small as possible. It is made clear that the LSM rocket launcher system can obtain very high energy-efficiency of 94 %. It is found from very large instantaneous power at a peak speed and relatively low required-energy that initial cost is very high but operating cost is very low.
