E-32 Aerospace Propulsion Systems Health Management
BackgroundEngine condition monitoring and rotorcraft HUMS(Health and Usage Monitoring Systems)can be used as a tool to track and restore engine performance, improve problem diagnosis, suggest solutions, promote better commercial and military aircraft operation, minimize in-flight failures, and reduce costs of engine maintenance. Because of these and other continuing objectives, the need for consolidated action by a group of experts to promote engine monitoring and rotorcraft condition monitoring know-how and standards was identified. It was deemed appropriate by the SAE Propulsion Division to assign this task to a special committee designated as Committee E-32. The committee has existed for over 40 years and has 26 active members. Purpose / Charter E-32 Committee serves as a forum to gather, record, and publish expert information in the discipline of aerospace propulsion system health management. The Committee gathers and analyzes requirements for propulsion system health management for the various types of air vehicle propulsion systems and develops standards and recommendations for the adoption of aerospace propulsion system health management devices that affect the operation of propulsion systems. Objectives Identifies potential propulsion system parameters suitable for sensing (pressure, temperature, vibration, etc.) and considerations involved in selecting parameters (potential problems, accuracy, cost, etc.), Analyzes the various approaches to aerospace propulsion system health management (e.g., airborne vibration health management systems, fault prediction capabilities, ground software interfaces, etc.) and establishes criteria for cost effective systems, and guidance regarding best practices for designing propulsion health management systems, Develops appropriate standards for aerospace propulsion system health management equipment and techniques; e.g., types of sensors, identification of signals which should be led to common diagnostic connectors, etc., Develops new requirements and uses for aerospace propulsion system health management to promote sustainable and cost effective operation of air vehicles, and Hosts technical conferences related to health management of propulsion systems. Provide a means to gain regulatory approval for utilizing EHM data in a range of maintenance activities.
* Redlines comparisons are available for those standards listed in the Revision History that contain a radio button. A redline comparison of the current version against a revision is accomplished by selecting the radio button next to the standard and then selecting 'compare'. At this time, Redline versions only exist for some AMS standards. SAE will continue to add redline versioning with ongoing updates to SAE MOBILUS.
