The mechanical hardware design challenges of implementing SEM-E format modules for a mission processor computer are examined. The computer consists of an air-cooled chassis, a high-density backplane, 18 digital SEM-E modules, five SEM-E format power supply modules, a power conditioner, and the internal wire harnesses. The complete computer weighs less than 78 pounds, and is approximately the size of a 3/4 ATR long chassis. The computer requires less than 400 watts of three-phase, 400-Hz AC power. A common thermal environment is provided for all modules. All modules are of surface mount construction and have aluminium covers that provide vibration, ESD (handling), and EMI (electromagnetic interference) survivability. This mission processor is designed for flightworthy applications. Formalized analysis and testing of the system verified the integrity of the processor.
