INHIBITED N2O4 ENGINEERING DATA.
Abstract
This program is concerned with collecting engineering data to further characterize the new storable oxidizer INTO which is NTO inhibited with 1 to 3 weight percent FN02. Sensitivity testing of 3 and 8 weight percent solutions of FNO in NTO is continuing. Special tubes have been constructed and calibrated for the detonation propagation tests on INTO. Tensile elastic moduli have been determined on stress corrosion test specimens of 250 maraging steel, 347 stainless steel, and 2219 aluminum. The 250 maraging-steel and 347 stainless-steel tanks have arrived at Rocketdyne. A 2014 aluminum tank, in which the 2219 aluminum specimens are to be stress tested, has not been received from the vendor. Atomic absorption methods are being developed to analyze INTO and NTO for dissolved Fe, Cr, Cu, Ni, Ti, and A1. Detection limits for these six elements dissolved in NTO have been decreased four-fold.
