Survey - Monomethylhydrazine Propellant/Material Compatibility

Abstract

A compilation of data describing monomethylhydrazine (MMH) specification grade propellant and material compatibility has been prepared based upon available information from literature searches. Materials include aluminum alloys and corrosion-resistant steels. Maximum temperature was 71 C (160 F). Although few data are available, and most at the lower temperature, it appears that, in general, monomethylhydrazine exhibits somewhat greater stability toward catalytic decomposition than does hydrazine (Hz) propellant. It is also generally considered that metals which are compatible with hydrazine are compatible with monomethylhydrazine. Therefore, based upon similarity and comparrison, it is not apparent that incompatibilities will be experienced with pure monomethylhydrazine and metals of interest up to a temperature of 43 C (110 F). However, no data are available on the conjoint effects of acidic contaminants, carbon dioxide and water. Hence, no predictions of the effects of these contaminants can be made with confidence.
