Electrostatic Discharge Testing
of Propellants and Primers

flyfeng

ABSTRACT This report presents the results of testing of selected propellants and primers to ElectrostaticDischarge(ESD) characteristicof the humanbody. It describesthe tests and the fixturing built to accommodateloose material (propellants) and the packed energetic material of the primer. The results indicate that all powders passed and some primers,especially the electricprimers,failed to pass established requirements which delineate insensitiveenergetic components. This report details the testing of components and materials to four ESD environments(Standard ESD, Severe ESD, ModifiedStandard ESD, and ModifiedSevere ESD). The purposeof this studywas to collect data based on the customer requirements as defined in the Sandia Environmental Safety & Health (ES&H) Manual, Chapter 9, and to define static sensitiveand insensitivepropellantsandprimers.

Electrostatic Discharge (ESD) Protection for a Laser Diode Ignited Actuator

Abstract
The use of laser diodes in devices to ignite pyrotechnics provides unique new capabilities
including the elimination of electrostatic discharge (ESD) pulses entering the device.
The Faraday cage formed by the construction of these devices removes the concern of
inadvertent ignition of the energetic material. However, the laser diode itself can be
damaged by ESD pulses, therefore, to enhance reliability, some protection of the laser
diode is necessary. The development of the MC4612 Optical Actuator has included a
circuit to protect the laser diode from ESD pulses including the "Fisher" severe human
body ESD model. The MC4612 uses a laser diode and is designed to replace existing
hot-wire actuators. Optical energy from a laser diode, instead of electrical energy, is used
to ignite the pyrotechnic. The protection circuit is described along with a discussion of
how the circuit design addresses and circumvents the historic 1Amp/1Watt requirement
that has been applicable to hot-wire devices.
