| Abstract: | A world-wide conceptual design study has been performed in support of highly reusable space transportation systems by using magnetic levitation as a launch assistance. The magnetic levitation techniques will be a good alternative of the next generation of launcher systems owing to its costeffectiveness and a perfect performance. For this purpose, a program is developed by testing a scale-model suspension system with HTSC over a 7 meter NdFeB track. An experimental platform has been constructed to measure the dynamic parameters of the PM-HTSC unit by a mechanical oscillator in this program. The dynamic experiment aims to investigate the stability and the dynamic response. Some technical details are also discussed in the article. |
