宇宙服务舱是一种低成本航天器,主要用于自主的材料科学试验样件的回收。它的起飞重量约为1400kg,可携带400kg 的负载(不包括电池)。再入舱的最大直径为2m。这种尺寸及重量的宇宙服务舱可用现有的或计划研制的各种运载火箭发射。系统和分系统设计体现了下列主要要求:设计成本低,首次飞行尽可能提前,可连续飞行7天。这个宇宙舱的设计是研制过程中的第一个里程碑,通过循序渐近的探索,加入一次性使用的太阳能电源舱及研制半弹道式再入大气层以提高着陆精度和改善再入大气层载荷,使宇宙舱的设计更先进。然后在总结不载人方案经验基础上实现载人宇宙舱的设计。这条途径减少了研制风险并降低了成本。本项研究是为联邦科学技术厅和德国宇宙开发协会做的,Dornier 是主承包商, 分承包商有 MBB、Kayser Threde、OHB 及不来梅大学的 ZARM。
The cosmic service module is a low-cost spacecraft mainly used for the recovery of autonomous material science test samples. It has a take-off weight of about 1,400 kg and can carry 400 kg of payload (excluding batteries). Reentry cabin maximum diameter of 2m. Space service capsules of this size and weight can be launched using a variety of launch vehicles currently available or planned to be deployed. The system and subsystem designs reflect the following key requirements: Low design cost, first flight as early as possible, and continuous flight for 7 days. The design of this cosmic capsule is the first milestone in the development process. Through a series of exploration, adding a one-off solar power capsule and developing a semi-ballistic reentry atmosphere to improve landing accuracy and improve reentry into the atmosphere, Space capsule design more advanced. Then the design of manned space capsule was realized on the basis of summing up the experience of unmanned programs. This approach reduces the risk of development and reduces costs. This study was conducted by the Federal Agency for Science and Technology and the German Association for the Development of the Universe.
