Smart Sensor Hub for Corrosion Monitoring

Corrosion of aircraft and rotorcraft is the single largest maintenance cost driver for the Navy and Marine Corps. In order to maximize aircraft availability and minimize inspection and maintenance demands, Luna proposes to develop a smart sensor hub to support corrosion monitoring of aircraft. The sensor hub will be the central application device for a complete corrosion monitoring system that detects early stages of corrosion and estimates corrosive severity. The smart sensor hub will perform wireless network communications, transducer communications, and data conversion and application functions. It will also provide power management to the transducer circuitry and energy scavenging devices to maximize service life. The system will have an open architecture and configurable interface with loading options to accommodate the widest possible range of sensors. Luna’s corrosion monitoring system will fuse diverse datasets for improved state awareness and reduced uncertainty in measuring corrosion damage and estimating useful life remaining. The Phase I program will conclude with a breadboard demonstration of the functional elements of the smart sensor hub including power management, control and communication, and data storage. Luna will also demonstrate corrosion sensor response to early stage corrosion damage of aircraft alloys
