Abstract

This work is devoted to propose the concept of the laboratory-scale test facility to provide a partial-g environment based on slope-sliding method, SSMe. SSMe mainly consists of the experimental rack and the less-frictional slope which enable to set at the prescribed angle against the ground. During the sliding operation, the experimental rack should freely “fall-off” in the direction of the sliding so that the normal component of gravity force against the slope surface only remains inside the rack. In this manner, partial-g environment is easily achieved and the target gravity level can be controlled by modifying the slope angle. In this paper, the simple demonstration was performed to verify this methodology works by using the small diffusion flame as the convenient gravity sensor. Several issues including engineering design are discussed in order to address the problems to be managed in future.
