Abstract: A Solid Instrumented Spherical Blast Impulse Recording Device (SISBIRD) includes a spherical housing formed of material that is resistant to an explosive blast wave from a test weapon. A test payload bore shaft is accessible through an opening in the spherical housing. A door is fastened over the opening in the spherical housing. A test data module is received in the test payload bore shaft. The test data module includes: (i) a three-axis acceleration sensor; (ii) a memory; and (iii) a controller. The controller is communicatively coupled to the three-axis acceleration sensor and the memory. The controller executes a data acquisition utility to record, in the memory, acceleration data in three-dimensions from the three-axis acceleration sensor during exposure of the spherical housing to the explosive blast wave.

Abstract: An Instrumented Spherical Blast Impulse Recording Device (ISBIRD) provides for survivable test measurement of an explosive blast impulse. The ISBIRD includes a spherical housing formed of a metal having a thickness sufficient to survive the explosive blast wave from a test weapon. A test data module of the ISBIRD includes: (i) a three-axis acceleration sensor; (ii) a memory; and (iii) a controller communicatively coupled to the three-axis acceleration sensor and the memory. The controller executes a data acquisition utility to record acceleration data in three-dimensions from the three-axis acceleration sensor during exposure of the spherical housing to the explosive blast wave. An internal support structure of the ISBIRD is attached inside of the spherical housing and attached to the test data module. The internal support structure centrally locates the test data module within the spherical housing during exposure to the explosive blast wave.
