MIL-STD 1901A Compliant In-Line Electrical Initiation System for Multifunctional IM/Legacy Propulsion Applications

Tanner and Special Devices, Inc. (SDI) will leverage a TRL-6 in-line Fireset/EFI device developed for future use with insensitive munitions (IM) warhead and propellant applications. In Phase I we will package and demonstrate at TRL-5 an in-line electronic Arm-Fire device (EAFD) for use in igniting solid rocket motors (SRM) with either IM or legacy propellants. The TRL-6 ignition system, packaged in ½-inch3, will be physically integrated into a ‘standard’ ¾-inch diameter SDI rocket motor igniter body for Phase I demonstration. We will vertically integrating high voltage components within the EFI device to minimize inductance and footprint. This innovative hybrid design approach using MEMS-based mass fabrication techniques creates a multifunctional approach to reliably initiate one or more EFI with nanosecond simultaneity. Similarly, multiple EFI devices can be digital-controlled to sequence initiation of a large array of divert and attitude control system (DACS) thrusters such as the 180 SRM used on PAC-3.
