内容記述 | Nutation dampers of a partially filled annular type have been often installed in satellites to remove their coning motion, if any. It is expected that during the cruising of a satellite the fluid slug in its damper tends to be separated into several owing to the existence of temperature gradient, and this results in the deterioration of its damping characteristics. Under such conditions it is better to mount the damper with offset in the satellite. The increase in kinematic viscosity ν of working fluid is also advantageous, but there is little merit in having a large size of inner radius γ. Anyway once this phenomenon has occurred, the drastic increase in the damping time is inevitable, so it is most important for the whole damper to be kept uniform in temperature. | |||||
