STRUCTURAL SHOCK DATA ACQUISITION DURING SEPARATION SYSTEM TESTS ON THE BOEING DELTA IV

摘要

Tests were conducted on the Delta IV Evolved Expendable Launch Vehicle (EELV) measuring the shock environment created during separation events that occur during launch, booster separation, and payload deployment. These tests were aimed at defining the pyrotechnic shock environments of the structure and adjacent components. The tests included measuring shock events during activation of the liftoff release system, solid rocket motor separation, common booster core separation (both forward and aft locations), and a payload fairing/shroud separation. The Boeing Company's Laboratory and Test Organization in Huntington Beach, California, has assembled and used high-capacity, efficient methods of instrumentation, data collection, and data processing that provide quality dynamic data for this type of shock testing.
