可重复使用的运载火箭（rlv）被视为迈向廉价太空运输的一步。日本政府考虑将一种称为NAL航天飞机的两级轨道飞行器作为未来潜在的RLV。该系统的总发射质量为193毫克，轨道器的有效载荷能力为8毫克，用于从圣诞岛发射的近地轨道（300公里）。本研究考察了NAL空间飞机概念的经济性能。为了获得相关信息，本文采用了多载机空间航母舰队成本模型（TRASIM）。为了对结果进行比较和验证，对航天飞机进行了并行模拟，航天飞机是目前唯一的部分可重复使用的运载火箭。对于NAL航天飞机方案，假设开发阶段为12年，而运营阶段为50年。作为一个结果，NAL航天飞机的每次飞行总成本（CpF）计算为4000万美元（2001年），而航天飞机的总CpF约为4.8亿美元（2001年）。
Reusable Launch Vehicles (RLVs) are seen as one step toward inexpensive space transportation. The Japanese Government considers a Two-Stage-To-Orbit Vehicle, called NAL Spaceplane, as a potential future RLV. The system has a total launch mass of 193 Mg and the orbiter’s payload capability is 8 Mg for LEO (300km) launched from Christmas Island. This study examining the economical performance of the NAL Spaceplane concept. To obtain relevant information, a multi-vehicle space carrier fleet cost model, called TRASIM, is used. For comparison and verification of the results, the Space Shuttle, which is the only existing partially reusable launch vehicle in operation, is simulated in parallel. For the NAL Spaceplane scenario it is assumed that development phase is 12 years while operation phase is 50 years. As one result, the Total Cost per Flight (CpF) for the NAL Spaceplane is calculated to $40 million (2001), while the Total CpF for the Space Shuttle is about $480 million (2001).
