The pyrotechnic system on an aerospace vehicle is always subject to intense scrutiny. Pyrotechnics are always one‐shot devices. This chapter focuses on electrically initiated explosive devices (EIEDs) most susceptible to electromagnetic interference, the low‐voltage single bridgewire devices. There are two main methods of protecting an EIED from radio‐frequency interference during storage and handling: a shorting plug and a Faraday cap. There are a number of important concerns when considering the overall vehicle system as opposed to the EIED independently. The first is knowledge of the electromagnetic environment in which it will be operating, and the second is the overall architecture of the firing system. The fundamental goal of grounding is to prevent potential differences between any two points in a system that could allow unintended currents to flow. A vehicle design that includes pyrotechnic systems brings with it a large amount of overhead in terms of necessary attention to design, procurement, analysis, and testing.
