Abstract
A system for calculating maintenance predictions and making improvements to performance deficiencies to one or more components in an on-board inert gas generating system (OBIGGS) is described. The OBIGGS components include an ozone converter, heat exchanger, inlet filter, and Air Separation Module (ASM). The system comprises a prognostic health monitoring (PHM) sensor network comprising at least one respective sensor coupled to each of the components of the OBIGGS. Each at least one respective sensor is configured to output a respective data signal corresponding to a performance condition of a respective component. A control unit is operatively coupled to each component and signally coupled to each respective sensor of the PHM sensor network. The control unit includes at least one test condition algorithm configured to analyze the respective data signal to calculate the maintenance prediction for the respective component.
