Abstract:

A method that has been used effectively to damp a librating gravity gradient stabilized earth satellite is described. The device consists of an extremely weak beryllium-copper helical spring plated with cadmium this is the primary damping medium. Some of the problems that confronted the experimenters during the development program are discussed, along with the numerous test data that were collected. Currently accepted theories describing the mechanism of the energy dissipation investigated are enumerated and evaluated. Author
