Test-bed design for extra-vehicle repairing and maintenance of manned spacecraft

The lifetime of a manned spacecraft can be extended by effectively repairing the disabled units or replacing overdue ones. Therefore, the extra-vehicle repairing and maintenance test technology on the ground is very important, and the key step is to establish a set of test-beds for validation. This paper discusses the simulation requirement for such a test bed, as well as the mission and functional arrangement, the system design, and the breakdown design. The integral test and measurement shows that this test bed can meet the simulation requirement for typical extra-vehecle maintenance operations with regard to the human-spaceflight mission, so that it may serve as an alternative for the widely-used neutral buoyancy facility or simulations based on the JACK.
