EFFECTS OF ATMOSPHERIC CONTAMINATION ON THE PERFORMANCE OF CARBON BRUSHES ON COPPER SLIP RINGS.

Abstract

The unsatisfactory performance of collector and commutator brushes in motor generators aboard nuclear submarines is introduced with the hypothesis that these difficulties are the result of atmospheric contamination. Following a survey of previously encountered contamination problems the experimental apparatus and procedures used to test this theory are described. Results of operation in eight simulated submarine environments are provided. (Author)
