Abstract : From November 1964 to 19 March 1965 seven solid propellant motor hazard tests and two high explosive calibration tests were conducted at the U. S. Naval Ordnance Test Station, China Lake, California. The primary purpose of the tests was to assess the blast yield of two classes of solid propellant material, when subjected to severe explosive shock, and to compare the propellant blast yields to those produced by a standard explosive. The following yields, in percent of TNT equivalency by weight, were determined from over- pressure and impulse data from a blast gage array: The highest yield of class 2 propellants tested alone approximated 40%; class 7 propellants tested alone produced well over 100%; and a combination of equal amounts of each class produced approximately 100%. The quantity and dispersion of fragments varied widely with the propellants used and with the test configuration. Additional tests are planned using different motor configurations, different propellants, and varying explosive stimuli.
