Abstract:

This report describes an unsteady pressure distribution due to a blast wave diffracting around a SPARTAN missile assembly. The pressure data were obtained from a series of five tests performed in the DASACON Conical Shock Tube Facility located at the Naval Weapons Laboratory, Dahlgren, Virginia. These tests were conducted during the period 17 Apr 72 to 8 May 72. During these tests the missile assembly was subjected to incident blast waves which had peak overpressures of from 2.9 psi to 11.8 psi and corresponding positive overpressure durations of from 380 milliseconds to 444 milliseconds. The report describes the pressure data for each test the empirical function used to represent these data. It then describes the method of integrating the empirical function at given times for the missile assembly sections of interest. The results of these calculations for all five tests are given at selected times. The calculation period covers approximately seven milliseconds beginning at the time the blast wave first encounter the missile assembly. These results are given as force vs time plots.
