Maintainability Simulation and Demonstration Equipment Description and Application

This paper describes the rationale, design concepts and mechanization of a versatile electronic simulation and demonstration device to support maintainability programs and projects in which Philco Western Development Laboratories is currently engaged under Air Force specification MIL-M-26512B, "Maintainability Requirements for Aerospace Systems and Equipment". Specific system maintainability design applications include those aspects of equipment and personnel subsystem design required to enhance malfunction detection, diagnosis, isolation and correction. The device consists of a six foot relay rack and an associated remote control unit which contain a Prime System Simulator and interrelated Maintenance System. The former is programmed to represent an operating data flow configuration at the block diagram level of a system or subsystem for which a maintenance system is to be designed. The latter provides a pool of possible man machine combinations for maintaining the simulated "prime" equipment.
