Following a very successful Phase I program, INTUITIVE proposes to continue the development of the standalone, Laser Ordnance Safe-Arm Distributor (LOSAD) to be used as a combination safe-arm device and laser energy distributor in this Phase II effort. LOSAD addresses the current need for a laser firing system safe-arm in existing and future MDA programs. The LOSAD utilizes INTUITIVE s basic optical block Ignition Safety Device (ISD) jointly developed with MOOG for THAAD s laser ordnance system. INTUITIVE will further develop the LOSAD during Phase II to minimize internal switching losses and build/demonstrate working prototypes of single channel and multiple channel devices. LOSAD s distributor function eliminates the need for duplicate laser firing units for initiating multiple devices. In addition, a higher-level of safety is inherent by use of the optical interrupt in the initiation train (as required by MIL-STD-1901A). The LOSAD will result in a significant improvement in overall safety for multiple device initiation with a desirable reduction in laser diodes and related firing hardware complexities and costs. No such device currently exits in inventory. Not only will LOSAD immediately serve as a back-up for the current THAAD ISD development program, but other DoD programs; NASA/Commercial Space systems; and the commercial demolition, mining, and explosives ordnance industries are prime potential customers. Bottom line: improved safety, reduced complexity, and reduced costs.
