Missile Site Rock Characterization and Penetration Test Results.
Abstract
The in-situ particulates from representative candidate missile deployment parcels have been characterized as part of the effort described in this report. An assessment of the ballistic penetration for the range of rock types found at proposed basing sites has been made for a Ti(6Al 4V) target material in order to evaluate the variation in the extent of damage to a missile shroud during ascent. The penetrability of the baseline tonalite granite was found to be comparable to several of the in-situ rock types for high impact velocities. Volcanic tuff and scoria which represent rock units that constitute 40 to 90% of the geology in any one candidate deployment sites surveyed were found to be two to three times less penetrating than the tonalite granite representative projectile types. A correlation of data bases for various projectiles was obtained from the current test results and the literature. From this correlation and the approach used for this effort, a test methodology for the characterization of shroud materials/concepts and motor-case protection materials is recommended. (Author)
