THE EFFECT OF SULPHUR ON THE WEAR OF CARBON BRUSHES AND COMMUTATORS IN AVIATION KEROSENE.

Abstract

The operation of submerged fuel-booster pumps on aircraft involves contact between aviation kerosene and the carbon brushes and commutators of D.C. motors. Laboratory experiments have been made to determine the importance of the sulphur present in the kerosene on the wear and electrical characteristics of a sliding coppercarbon interface. Significant amounts of reactive sulphur can be liberated by dissociation of thiophenes, etc, when arcing occurs. Although this sulphur reacts with copper, its presence does not appear to be detrimental to the electrical properties of the contact. The effect of reactive sulphur on the wear of copper is negligible in comparison to the direct effect of arcing itself on wear. (Author)
