Titanium Response to Simulated Nuclear Cloud Particle Environments. Volume I. Analytical and Experimental Results.
Abstract
The response of titanium alloy (6Al-4V) to simulated nuclear cloud particle environments is addressed in this combined experimental and analytical study. The results are applicable for ascent vehicles with hot titanium structures flying through nuclear burst ice or dust clouds. A three-phase exploratory program was conducted: An initial oxidation test series using an SAI-designed test fixture, a test series using the AEDC Dust Erosion Tunnel (DET), and a particle impact test series using the SAI hypervelocity impact facility. Analytical modeling of titanium oxidation produced results in close agreement with experiment. Although increased oxidation of titanium was confirmed in H2O vapor versus O2 environment tests, no net effect of liquid H2O and O2 oxidation under combined particle erosion conditions was observed in the AEDC DET. This is believed to be the result of the heat of vaporization of H2O exceeding the heat of oxidation of H2O vapor. (Author)
