Abstract:

Pyroshock events in space vehicles lead to high-magnitude short-duration structural transient events that can cause malfunction or degradation of electronic components, cracks or fractures in brittle materials, local plastic deformation, or materials to experience accelerated fatigue life. In the 1960s, Martin Marietta performed testing to develop a set of knockdown factors looking at shock attenuation with distance. With the advancement of data acquisition technology, however, the need to validate their work exists. This work looks at full-scale separation pyroshock test data collected by Orbital ATK during NASA's Ares I-X program and compares it to the historical standard provided by Martin Marietta.
