Very High Frequency Vibration Monitoring System for Accessory Health Management

Impact Technologies, in cooperation with the major propulsion engine manufacturers (OEMs) propose to develop and demonstrate a unique very high frequency vibration monitoring system that integrates various vibro-acoustic data with intelligent feature extraction and fault isolation algorithms to effectively assess engine accessory component health. The system will be capable of reporting on the early detection and progression of faults by utilizing the optical and acoustic frequency measurements for improved, incipient anomaly detection. The gas turbine engine vibration monitoring technologies proposed herein will address the existing O&M goals for current USAF engines, as well as those set forth by the USAF’s VAATE Intelligent Engines initiative, and F-35 prognostics and health management programs. These system features will be integrated in a state-of-the-art vibration monitoring system that will not only identify faults more confidently and at an earlier stage, but also enabling the prediction of the time to failure or a degraded condition worthy of maintenance action.
