Integration of a Wireless Sensor Data Aggregation System and HUMS

In recent years, wireless sensor networks have demonstrated efficacy in structural health monitoring for rotorcraft. Despite the utility of these networks, they have yet to become a standard part of on-board health and usage management systems (HUMS) for rotorcraft. For instance, recent LORD MicroStrain network deployments on rotorcraft run as separate parallel data collection systems irrespective of the on-board HUMS. The benefits of system integration include enabling wireless network control based on data collected by the HUMS, centralizing data storage on the HUMS where a significant portion of data is already stored, and allowing the use of existing ground based infrastructure. Work presented here focused on integrating a LORD wireless sensor network with a Goodrich IVHMU.
