Abstract
When an NASA standard initiator (NSI) combusts within the confinement of a pyrovalve, debris is generated and entrained into flow. This debris can originate from the closure disc, the zirconium potassium percholate (ZPP) reactants, and perhaps material ablated from the valve body such as aluminum. …
