本文提出一套新型的航天运载系统，即“通天桥”航天运载系统。基于真空磁悬浮原理，结合我国目前磁悬浮列车的技术储备与发展，对真空管道的实现、磁悬浮管道的构建、磁悬浮方式的选择等进行了深入研究。结合我国得天独厚的地理优势，“通天桥”系统中航天器脱离管道地点设置在喜马拉雅山脉的顶峰。当航天飞行器脱离“通天桥”系统之后，采用火箭发动机，最终航天运载器以7.9 km/s的速度进入太空预定轨道。仿真结果表明，与传统航天运载器相比，该“通天桥”航天运载系统在提高航天器的有效载荷率、重复使用性，节能环保和运载安全等方面有独特的优势。 A new concept of the space transportation system is presented, namely “Heaven Bridge” space transportation system. Based on the development of maglev train in our country, this new space transportation system is composed of vacuum magnetic levitation pipeline, flight transportation vehicle, and other equipment on the ground. Combing with the unique geographical advantage, launching spot of “Heaven Bridge” is located at the top of Himalayas Mountain in China. When spacecraft separates from the “Heaven Bridge” system, the spacecraft can be boosted by rocket engines and then reach the appointed target orbit in space at the speed of 7.9 km/s. Comparing with the traditional space transportation systems, this new concept system “Heaven Bridge” pro-vides with the following excellent properties: skyscraping efficiency payloads, reusable and recy-cling, environmental-friendly, safety transportation and so on.
