摘要： 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.

摘要： A method of recovering performance of an air separation module (ASM) is described. A recovery system includes an air source providing inlet air, a filter to output clean air and a heater heating the air. The ASM is coupled to the system and comprises a hollow fiber membrane to output nitrogen enriched air (NEA) exhaust. The method comprises operating the system with the air source and heater in a default condition; measuring an initial purity of NEA exhaust; adjusting the air source and/or heater based on the initial purity; operating the system after adjusting the air source and/or heater; returning the air source and heater to the default condition; measuring a recovered purity of NEA exhaust; and determining whether the recovered purity is within tolerance. If the recovered purity is within tolerance, system operation is terminated. If the recovered purity is not within tolerance, the steps are repeated.
