PENDULUM-TYPE NUTATION DAMPER USED IN THE NASA ATMOSPHERIC STRUCTURE SATELLITE, S-6.
Abstract
A reliable passive device was developed for quickly damping out nutational motion of the spin-stabilized NASA S-6 satellite (Explorer 17). The operating principles for this twin-pendulum damper were determined with the aid of a small table-top gyroscopic model. Final developmental testing was done with a full-scale synamical simulator. Formulas for each of the three basic design criteria are derived. These formulas are (1) for tuning the damper to the nutational disturbance, (2) for the selection of the viscous friction coefficient of the pendulum hinge, and (3) for the guarantee that the desired final balanced and stable configuration of damper and satellite will be obtained.
