Sensor Selection Code

Systems health monitoring for aerospace systems is increasingly emphasized, and as such is the need to select sensors not only for system performance but also for health assessment purposes. Based on the particular health monitoring philosophy of the system, an optimum sensor suite exists from the available pool of potential sensors that maximizes the fault detectibility and in general fault identification of the system based on requirements. To perform sensor selection for these types of systems a methodology was developed in house called the Systematic Sensor Selection Strategy (S4). Originally, this methodology was applied in a space type system, and more recently with enhancements, this methodology is been demonstrated for aero-propulsion systems. An interdisciplinary team is currently demonstrating this technology for aero-propulsion systems as well as applying it in certain areas in Space Exploration.
