During this deployment process, the artificial satellite 1 is given a reaction torque from yaw and begins to rotate. FIG. 2 shows the situation at this time. As shown in Figure 2, during deployment, the yaw wire deploys tangentially to the satellite 1, but after deployment is complete,
The direction of yaw development changes direction in the radial direction of rotation. When the deployment direction reaches the radial direction, the release mechanism 8 separates the yaw from the artificial satellite 1, completing the spin-up. FIG. 3 shows the situation at that time.

らない点において最適である。 In addition, passive (while applying the energy held by the wire itself to the rotated object as rotational motion,
Since the object to be rotated is spun up (in the sense that it is separated from the object to be rotated), there is an advantage that energy sources such as fuel and electric power are not required for rotation. Therefore, it is ideal as a spin-up mechanism for an artificial satellite that is separated from a rocket because it is a simple mechanism and does not require a large scale.
