Abstract : This program is concerned with extending the engineering evaluation of the new storable liquid oxidizer INTO which is NTO inhibited with 1 to 3 weight percent FNO2. Storability tests are being conducted on INTO at ambient temperature and at 70 C in aluminum, iron, and titanium tanks of 10- to 24-gallon volume. Titanium 6Al-4V specimens uniaxially stressed to 90,000 psi and stored in INTO at ambient temperature and at 70 C are being observed for possible stress corrosion failures. No failures have been detected after 6 days of testing. Small-bomb storability tests (20 milliliters) in iron and titanium alloys at ambient temperature and at 70 C are now in their sixth month. Chemical analysis for FNO2 content indicates that INTO is storable in A286 steel and that it probably is not storable in titanium 6Al-4V. (Author)
