FINAL REPORT OF FIRE AND IMPACT TESTS, JOINT AEC-DOD VULNERABILITY PROGRAM (WEAPON IMPACT TESTING USING ROCKET SLEDS) (June 1959 to June 1963) Volume V, Part Ⅰ

摘要

Thirty-two weapon impact tests wore conducted using expendable rocket sleds to propel the weapon systems into the impact area. The objective was to determine the minimum impact velocities required to cause detonation of the high-explosive elements of various weapons. Test conditions which represented a "most severe" foreseeable impact situation were chosen;each weapon, in its most vulnerable attitude, impacted a massive target with a concrete slab face. The slabs were suspended over the sled track rails on a target structure which straddled the rails, such that the weapon impacted the target slab fully while the. rocket sled passed freely beneath the target structure.nDuring weapon impact, signals from weapon instrumentation were monitored by streak photography, by telemetry, and by explosive devices. The sequence of events during weapon crushup, deceleration history of the warhead, and location of reaction initiation within the warhead were measured. An umbilical cable link was maintained between the sledborne telemetry and the weapon instrumentation for transmission of instrumentation signals as the weapon separated from the sled during impact. The telemetry equipment, mounted on a monorail extension forward of the sled and protectively packaged in crushable foam, was consistently recovered in good condition despite weapon detonation nearby, and despite tumbling across the desert.nThis experimental technique produced clean weapon impacts, to which weapon responses were self-consistent and reproducible. Interpretation of the instrumentation information which was obtained permitted a quantitative analysis of the impact phenomena in a majority of the runs.
