INHIBITED N2O4

Abstract

This program was originally concerned with evaluating a new storable liquid oxidizer, INTO, which is NTO inhibited with a fluorine-containing oxidizer, F3NO. Storability results showed that F3NO is not compatible with NTO at elevated temperatures. FNO2 was substituted as the inhibiting fluorine oxidizer and this new propellant system is called INTO-2. Its constituents were found to be compatible at 70 C. Long- and short-term corrosivity tests were initiated. The 7-day compatibility tests with nonmetallics were completed in NTO, INTO-1, and INTO-2. Results indicate that INTO-2 is more compatible than INTO-1 with the materials studied. There was little difference between NTO and INTO-2. Conductance measurements were completed on INTO-1. Results indicated that galvanic corrosion will not be a problem. INTO-2 was prepared by reaction of fluorine with NTO and the resulting mixture was shown to react with added water to bring the water equivalent down to 0.03%. Analytical methods have been developed for the analysis of INTO-1 and INTO-2.
