Excelitas Rocket Motor Initiator

Rocket Motor Initiators

Our patented Rocket Motor Initiators and Through Bulkhead Initiators are designed to work with single- and multiple-pulse rockets, as well as those platforms that might not currently have MIL-STD-1901A-compliant initiators. Excelitas initiators are designed to work in conjunction with our Ignition Safety Devices and low-energy, low-profile Blue Chip® Detonators to provide a comprehensive and reliable rocket ignition and firing solution.

An Excelitas Rocket Motor Initiator consists of a covered and sealed firing circuit which is connected to an Ignition Safety Device (ISD) via a three-wire cable and connector.

Our Through Bulkhead Initiator consists of a stainless-steel housing fabricated to proprietary dimensions to ensure proper energy transfer as well as maintain isolation against back pressure.

The energetic materials loaded into the initiators are HNS II and BKNO3. The initiator is welded closed with an etched closure disc to maintain a hermetic seal and to open in a controlled, defined manner when initiated. The initiator is not damaged with applied voltages up to 500 volts. It functions when a sufficiently high voltage is applied.

When mated with an Excelitas initiator electronics assembly, the Through-Bulkhead Initiator can be located remotely from the ISD in order to accommodate any variety of packaging constraints.
