Cell appratus checks resistivity of nitrogen tetroxide propellent to control CORROSION in MISSILES Available to Purchase

Brief discussion of cell apparatus used to make continuous analysis of water content in nitrogen tetroxide propellant systems as a method of corrosion control in intercontinental ballistics missiles. Aluminum alloys used for missile propellant tanks handling nitrogen tetroxide suffer severe corrosion when water content in system rises above 0.2 percent by weight. Studies showed relationship between water content and specific resistance of missile propellant. Discusses formula for determining specific resistance of a liquid. Shows equipment used for this method of water content analysis and outlines its advantages over laboratory analysis methods.
