Spacecraft Shock Environment Induced by Nose Fairing Separation Pyrotechnics

摘要

The report presents the results and the methods used to determine the shock levels, and the fragility of selected critical components parts and spacecraft sub-assemblies during full scale, 823 Spacecraft, nose-fairing separation tests under simulated altitude conditions. Eight spacecraft subassemblies were tested. Of these eight subassemblies, two were monitored for transilent malfunctions during the separation tests, and six to determine if permanent damage would occur. There were no indications of transient malfunctions or permanent damage to any of the eight subassemblies as a result of these tests. A total of 51 component parts were subjected to the separation shock. Of these component parts, five sustained physical damage of which three could be considered as potential sources of system malfunction. (Author)
