| Abstract: | The launching cost model of reusable launching vehicle based on Life Cycle Cost(LCC) analysis is presented. The LCC of various reusable launching vehicle programs with different stages are calculated by applying the newly built analysis model. Components of the LCC are presented specially, and the relationship between each of the components of the LCC and stage number is also analyzed. The result indicates that the LCC of Two Stage to Orbit (TSTO) reusable launching vehicle program is the lowest, so TSTO reusable launching vehicle program is the relatively optimal selection based on the present developing level. |
