Rotary Wing Structural Life Tracking Architecture

Technical Data Analysis (TDA) presents the architecture development of its rotary wing dynamic component structural life tracking system, HeloTrack.net, which was developed for the US Navy to meet Condition Based Maintenance (CBM) objectives. Methods of fatigue lifing are discussed in the context of improving accuracy for end of life predictions of rotary wing fleets. TDA improves on the current damage calculation process of hours based tracking with HUMS regime recognition and direct loads monitoring. This paper also presents methods for collection and reconciliation of aircraft configuration and fleet logistics data using both legacy paper-based tracking systems as well as advanced Radio Frequency Identification (RFID) tag networks. The union of configuration data and usage data allows for implementation of accurate life tracking techniques. Capabilities and design of the web-based user interface for HeloTrack.net are also discussed.
