Temperature and Pressure Profiles Obtained during Burn of a SPARROW MK 38 Mod 0 or Mod 1 Motor in a 15,300 Cubic-Foot Magazine. Part 2

Abstract

SPARROW MK 38 MOD 0 or MOD 1 motors were ignited in two tests in an instrumented 15,300 cubic-foot magazine under conditions simulating accidental ignition of these motors in shipboard service using the wet or dry sprinkler system as the damage control mechanism. The results provided a detailed temperature and pressure profile in the magazine; and thermal characteristics for bare, inert, instrumented ZUNI motors, bare, inert, instrumented, all-up configuration of SIDEWINDER and ZUNI missiles, and inert, instrumented, containerized, all-up SIDEWINDER and ZUNI missiles located in the magazine. Temperatures and pressures within the magazine reached a peak of 1185 F and 19.3 psig. external and internal temperatures for the instrumented, inert ordnance peaked at 1200 F and 455 F, respectively. Data from these tests will assist in evaluating the relative effectiveness of the wet vs. dry sprinkler system in preventing chain reaction of ordnance in deep stowage magazines during motor burn, and in evaluating thermal systems designed for explosive ordnance.
